2.2 Notes Concerning Disposal

Disposal of packaging materialsPlastic foil is used to protect the units, wooden crates as exterior packaging and wooden pallets for support. The packaging foils, securing bands and foam sheets are made of polyethylene (PE), the CFC-free cushioning parts are gen-erally made of foamed polystyrene (PS). These packaging materials consist of pure hydrocarbons and are therefore recyclable. The securing bands are made of steel. The wooden crates are not chemically treated.

Dispose of all packaging materials in accordance with regionally applicable regulations.

Disposal of the air-conditioning unitWhen the air-conditioning unit or its components are dis-posed off, the regionally applicable regulations for waste treatment and disposal must be observed.

Rittal offers taking back all air-conditioning units and their acces-sories provided these are shipped to us free of charge. Profes-sional disposal is then guaranteed.

A precondition is supply in cleansed condition: The units must be free of dangerous substances (air freight). The filters must be disposed off by the owner of the system. Refrigerants and oils from the refrigerant circuit may remain inside the unit.

Components added by third parties and machine parts that have not been supplied directly by Rittal are excluded from this take-back offer.

DANGER! Injury through falling objects! When transporting the unit with a hand pallet truck, forklift truck or crane, do not step below the lifted load!

ATTENTION! Hazard of damage to the air-conditioning unit! Protect the air-conditioning unit from strong shock! Do not put the air-conditioning unit down on one of the corners! Do not burden housings in one spot only! Never lift the unit at pipes or other interior parts! When transporting the unit with a hand pallet truck or forklift, be sure the fork passes all the way under the module!

For transport and placement at the installation site, the air-conditioning unit has been braced with straps standing upright on a palette. It must remain on this pallet until it has been transported to a level floor allowing use of industrial trucks.

To unload it from a truck by means of a forklift truck, the unit should still remain on the pallet and should be secured on all four corners using belts to prevent tipping over.

When setting the unit down, ensure that the floor is capable of bearing its weight and that the unit cannot tip over!

Horizontal transport to the installation site: The unit has been designed for vertical transport to the installation site. If it shall be introduced into the building in horizontal position, proceed with utmost caution to ensure the walls and the heat exchanger are not damaged. We rec-ommend to contact Rittal Service before.

2.5 Installation

The installation site must be protected from freezing.

Install the unit so that air can be aspirated or blown out unhindered at all connections.

To ensure even air supply to all air outlet plates, the supply air must be conducted inside the double floor with as few as possible obstructions. Cable ducts and water conducting lines should be installed so that they do not cross the air pas-sage inside the double floor!

To ensure even air supply to all air outlet plates install the unit at the face end of the rack rows!

Temperature and humidity sensors should not be directly affected by machines or equipment giving off heat or mois-ture. Prevent exposure to direct sunlight!

Ensure that sufficient space is available for operation and maintenance work. The space for maintenance in front of the unit should be at least 1 x housing depth. Infront of the base leave a free space of at least 600 mm for removal of the fan.

Ensure sufficient lighting of the installation site.

Ensure that the vibration insulation between the unit and the building structures is sufficient.

The vibration-insulating, height-adjustable unit feet of the fan base and the fan base achieve dampening of structure-borne noise and allow to compensate for uneven floor.

2.7 Media Connections

The installation and first operation must be carried out exclu-sively by qualified mechanics and electricians or by Rittal service personnel.

Depending on the unit type and configuration, the following con-nections must be made according to the overview drawing in the data section.

pumped chilled water (PCW supply and return)condensate drain (condensate)humidifier water (supply and drain)hot-gas refrigerant (HG-KM)fluid refrigerant (FL-KM)

All connections are unmistakably identified by the designations here given.

To achieve air-tightness class L1, all media connections must be made air-tight, to ensure no air may be drawn in or blown out at the connecting lines.

Supply lines in generalAll supply lines must be laid and connected according to the applicable rules for refrigerating and piping. Remove the plugs, feed the lines through the cut-outs in the fan base or base box and connect them to the lines inside the unit. Install lines without constraint!

NOTE: When installing lines, ensure their accessibility for maintenance and sufficient length allowing to pull out the fan drawer! The space for maintenance in front of the fan should be at least 600 mm. Never install lines across the face of the fan! When installing lines, be sure the supply-air flow inside the dou-ble floor is hindered as little as possible. Install lines so that they do not cross the air passage inside the double floor!

Chilled-water lines (CW)When connecting the return line, install a union on site below the control valve!

Connect the external piping system to the supply and return connections at the unit (inside threads).

Install the insulation hose, e. g. of Armaflex, and paste it sealproof to the connections at the unit.

Carefully rinse the piping system; via the inlet or KFE cock at the heat exchanger fill the system with medium and vent it at the venting valve on the collector of the heat exchanger.

Check for tightness.

Chilled waterThe chilled water must have drinking water quality. A mixture of glycol and drinking water is likewise admissible. The con-centration must be >20% for Antifrogen N, and > 25% for Antifrogen L. If the concentration is too low, flakes or slime may form due to biological growth, resulting in reduced flow. The same may be caused by leaks or penetration of light. The concentration must be checked at least once per year. If chlorinated water is used with a concentration exceeding > 0.3 ppm this may cause holes due to corrosion!

If contamination must be reckoned with, install a filter with a pitch of < 0.6 mm.

Refrigerant lines leading to an external condenser (DX)

Be sure to observe the separate instructions for the con-denser!

When planning the piping layout ensure that the lines between the air-conditioning unit and the condenser are as short as possible. Only allow for exceptions to save unnec-essary bents.

If at all possible, do not conduct refrigerant lines through rooms in which people are staying, such as offices and meeting rooms.

Install horizontal hot-gas and suction gas lines always with inclination toward the condenser.

If the hot-gas line is longer than 25 m, an oil separator must be installed.

When laying out the refrigerant lines, be sure no sag is cre-ated in which oil may collect; install oil traps if necessary.

If the condenser is installed higher than the air-conditioning unit (e.g. when installed on roof-top), oil traps must be installed in the hot-gas and suction gas lines every 2.5 to 3 metres, even if an oil separator has been installed.

If the condenser is installed more than 5 m lower than the air-conditioning unit (e.g. when installed outdoors), subcool-ing is required. Consult with Rittal in such cases.

If a refrigerant collector is provided for, it must be installed in flow direction directly behind the condenser in the liquid line and must be installed at a lower level than the condenser.

If the system operates at an ambient temperature of below -16 °C during the winter season, the collector must be installed near the air-conditioning unit. Additionally the sys-tem must be furnished with a head pressure control valve and a non-return valve in the refrigerant line to prevent excessive accumulation of refrigerant at the coldest spot in the system, that is at the condenser.

Pipe bracketsInstall pipe brackets every 2 m for semi-hard copper pipes, every 1 m for soft copper pipes and ensure vibration damp-ening.

The first pipe bracket downstream of the air-conditioning unit and upstream of the condenser should be elastic. Pipe brackets must not be too close to bents, to allow elongation of lines.

The piping system may be made exclusively of special cop-per pipes that have been cleansed inside and sealed on both ends.

Installing the pipingTo connect the refrigerant piping system open the line ends on the unit and the condenser. Upon opening, gas must escape audibly (ex works nitrogen filling); this is evidence that there are no leakages in the refrigerating circuit.

Cut lines exclusively using a pipe cutting device!

Never saw lines open, to prevent generation of sawing swarf!

Only solder lines while using nitrogen as a protective gas! To achieve this, introduce dry nitrogen on one end of the line already prepared. Before starting soldering, introduce a gen-erous nitrogen flow, when starting soldering reduce it to a minimum and maintain this low protective gas flow during the entire soldering process.

Before soldering the last connection, open one screwed union, to prevent overpressure in the piping system. Upon soldering retighten the connection!

As an alternative to soldering you may use crimping. How-ever, limit crimped connections to annealed pipes with a diameter of max. 20 mm! After cutting the pipes, slightly open the pipe to the correct inside diameter. The crimps must be tightened to the correct torque using a torque wrench.

Insulation of the liquid lines:

The liquid lines outside the building must be insulated using a heat insulation of Armaflex or an equivalent material.

A wall thickness of 9 mm is recommended. The insulation effect increases only slightly with rising wall thickness.

Insulation of the hot-gas lineThe hot-gas lines must be insulated inside the building wher-ever they could be touched, to prevent burns.

Working on the refrigerant circuit, general information

Pressure stability and tightness inspection:

Fill and pressurise the system using dry nitrogen at a pres-sure of min. 28 bar. The Rotalock valves on the intake and pressure sides of the compressors must be closed. This ensures the compressors are not subjected to the test pres-sure.

Check the system for tightness. We recommend to inspect all connections for tightness, including screwed joints, by applying moisture with a brush or by spraying.

EvacuatingUpon successful pressure testing, the air still remaining in the system must be removed. To do so, connect a vacuum pump and evacuate the system to a pressure of < 0.3 mbar (absolute pressure).

If at all possible evacuate from both ends of the compressor, that is from the intake and the pressure side.

Fill the system with dry nitrogen and repeat the evacuation. This removes air and remaining moisture from the system.

Filling with refrigerantIf possible, fill the system with a specified refrigerant weight or by checking at the sight glass. Fill the refrigerant in liquid state into the liquid line until the filling volume reaches the calculated filling volume most exactly. Thereafter switch the unit on and, while it runs, continue filling carefully and slowly from the intake side of the compressor, until no more bub-bles are visible at the sight glass.

Note the refrigerant volume filled in on the nameplate.

Refrigerant filling volumes for unit and condenser see techni-cal data. Determine the refrigerant filling volume for the pip-ing system from the individual lengths and interior diameters of the refrigerant lines.

The weight of the refrigerant volume actually filled in is deter-mined during filling by means of a refrigerant bottle.

If an oil separator is provided for, it is normally already installed in the unit.

Install the oil separator in the hot-gas line in vertical position as close as possible to the compressor.

Install the non-return valve provided at the outlet of the oil separator.

Fill the oil separator through its outlet with 0.5 l of the same oil used in the compressor (initial filling), to ensure the oil float switch is activated upon system start.

We recommend to protect the oil separator from vibration and gas pressure fluctuations by means of vibration and pul-sation dampers installed between the compressor and the oil separator.

Condensate drain, ball-type return lock siphon and external pump (optional)

Conduct the on-site HT pipe for condensate drain with one end through the fan base or base box, through the mem-brane grommet in the unit bottom and connect it to the con-densate drain connection inside the unit.

Lay the pipe for the condensate drain using HT tube in such a way that the condensate can flow into a drain or funnel at a slope of at least 3° and free from counter pressure (never connect it directly to the on-site sewer system).

Install the ball-type return lock siphon as well as an external pump (optional) downstream of it in the condensate drain pipe as closely as possible to the outlet opening inside the fan base or base box.

We recommend to install the pump in a pan or similar collec-tor. The hose connected to the pump should have an inside diameter of 13 to 15 mm.

Be sure it remains accessible for maintenance!

The special siphon with return lock supplied separately must be used to prevent condensate from being sucked back into the unit in case of negative pressure or pressure fluctions, e. g. upon power-up of the unit.

Open the siphon by turning the triangular cap left until stop.

Minimum diameter of the supply line: 8 mm

Admissible inlet pressure 1.0 ... 10.0 bar (system without pressure fluctuations). For supply pressures > 10 bar the inlet pressure must be reduced to 2.0 bar by means of a pressure reducing valve. For supply pressures < 1 bar con-tact Rittal.

Supply volume: 1 l/min per 15 kg/h steam output

Admissible inlet temperature: 1...40 °C

A shut-off valve should be installed into the inlet line outside the unit.

Humidifier returnConnect the humidifier return to a dedicated ball-type return lock siphon! Further down it may join the condensate drain pipe only downstream of the siphon of the condensate drain!

Connect the humidifier outlet to the connections at the air-conditioning unit.

Use only heat-resistant installation materials!

The water returns pressure-free. To ensure the water cannot bank up, the first section of the drain line should lead verti-cally down for at least 50 cm. The humidifier return must be connected to a dedicated ball-type return lock siphon. Fur-ther down it may join the condensate drain pipe only down-stream of the siphon of the condensate drain!

The minimum interior diameter of the drain line of 30 mm must be adhered to for the entire length.

The drain line should be readily accessible for inspection and cleaning and must be fastened appropriately.

First operation:Open the water supply line.

As soon as the air-conditioning unit is switched on, the humidifier electronics are activativated and perform a self-test during which all LEDs of the controller unit ECCM light up one after the other. As soon as humidity is requested, the heating current is switched on. The inlet valve opens and the cylinder is filled with water. As soon as the electrodes dip-ping into the water heat it up, the green LED lights up, and after approx. 5 to 10 minutes steam is generated.

The low conductivity of very soft water may result in the maximum steam capacity not being reached during the initial hours of operation. However, the continuous evaporation process will subsequently result in sufficient conductivity. If the conductivity of the local water is < 300 μS/cm, consult with Rittal customer service concerning a special steam cyl-inder.

De-commissioningClose the water supply line.

Press the desludging/info button (50S1 or 51S1) briefly, then wait 5 to 10 minutes, until the steam cylinder is empty.

Reset the circuit-breaker (50S2 or 51S2) to 0; this separates the steam cylinder from the power supply network.

6.7 Free Cooling (FC) (optional)

The scope of supply of the FC option comprises a Free-Cooling add-on box with two exhaust air louver dampers and electronic safety drives fastened to it. An outdoor air temper-ature sensor is supplied separately.

The special design of the Free-Cooling add-on box allows highly energy-efficient heat removal from thermally loaded rooms, since the outdoor air is used directly for cooling. The required conditioning of the room is achieved by constant mixing of cold outdoor air with warm return air from the room. The outdoor air conducted into the room results in slighly higher pressure inside the room. This in turn causes exces-sive air to excape outdoors via the exhaust-air dampers.

This principle is referred to as “direct free cooling” and only makes sense where the outdoor air is colder than the return air from the room. If the outdoor air temperature rises above the return air from the room, the unit switches over to recir-culating-air operation; the heat from the room is then removed by refrigeration (mechanical cooling).

Description of the hygrostatThe humidity measuring element which is manufactu-red by Galltec® under the name "Polyga®", consists ofseveral plastic fabric bands each with 90 individualfibres with a diameter of 0.003 mm each.The fibres areprovided with hygroscopic characteristics by a specialprocess. The measuring element absorbs and des-orbs moisture. The effect, swelling predominantly inlongitudinal direction, is supplied to a microswitch withan extremely low switching travel via a suitable leversystem. The measuring element reponds rapidly andprecisley to the change in air humidity. It is possible toadjust the lever system by setting the setpoint knob sothat the microswitch is actuated when the set airhumidity is reached.The hard-shaped measuring element isaccomodated inside the housing and must beprotected against coarse dust, dirt and water. Thesensors are designed for pressureless systems. Theinstallation location must be selected so thatcondensed water cannot enter the inside of thehousing. Any installation position is possible,preferably with ventilation slots at right-angles to winddirection.

Mounting

The hygrostat must not be exposed to any direct watercontact, e.g. splash water when cleaning the air-conditio-ned room etc.The place of installation must be selected so that a repre-sentative air humidity measurement is guaranteed, i.e. themeasured humidity values at the place of installationshould correspond to those of the room as far as possible.If possible, the hygrostat should be located in the air flow.

>

>

>

It is thus of extreme importance that the temperature isconstant for measurements of the relative air humidity.The air must be homogenous, e.g. possess constanthumidity and temperature for the whole duration of themeasurement.

The measurement location of the humidity controller should beselected such that there is no build-up of condensate on or in thedevice. This applies particularly for operation with a voltagehigher than 48V. If the voltage is higher, there is a risk of voltagearcing in the event of water condensation on the microswitch orconnecting terminals which might destroy the controller. In thecase of voltage below 48V, the humidity controller can be usedup to 100%RH.The humidity controller should not be used in aggressive media.

Influence of the relative air humidityfor a temperature fluctuation of ±1°C referred to various roomtemperatures.

MaintenanceIn case of clean air the measuring element is mainten-ance-free. But aggressive and solvent containingagents as per their type and concentration may causefaulty measurements. Water repellent protective filmforming deposits on the sensor, like resin aerosols,lacquer aerosols, fumigant substances etc. are harmfulto almost all types of humidity sensors.

ATTENTION: No warranty will be guaranteed when innerparts of the device have been handled.

Operating Instructions GB

ECD-002 display/keypad unit (LEDs and button functions)

Setup of main parameters (need to be checked/modified before start-up) using ECD-002 • Make sure that digital input is 0V (open). Turn the power supply ON. Important: Three main parameters i.e. refrigerant type (u0), pressure sensor type (uP) and valve type (ut) can be set only when digital input is open (0V) while the power supply is ON (24V). This feature is for added safety to prevent accidental damage of compressors and other system components. • For easy setting of main parameters, follow the pictorial procedure of “Quick

start-up” on the attached individual paper. Once the main parameters have been selected/saved the EC3 is ready for startup. All other parameters can be modified at any time during operation or standby if it is necessary.

Start-up Start the system and check the superheat and operating conditions. The EC3-X33/53 is fully functional without keypad/display unit. ECD-002 may be removed or connected at any time.

Procedure for parameters modification using ECD-002 The parameters can be accessed via the 4-button keypad. The configuration parameters are protected by a numerical password. The default password is “12”. To select the parameter configuration:

Press the PRG button for more than 5 seconds A flashing 0 is displayed Press or until 12 is displayed; (password) Press SEL to confirm password Press or to show the code of the parameter that has to be changed; Press SEL to display the selected parameter value; Press or to increase or decrease the value; Press SEL to temporarily confirm the new value and display its code; Repeat the procedure from the beginning "press or to show..."

To exit and save the new settings: Press PRG to confirm the new values and exit the parameters modification procedure.

To exit without modifying any parameters: Do not press any button for at least 60 seconds (TIME OUT).

Reset all parameters to factory setting: • Make shure that digital input is 0V (open). • Press and together for more than 5 seconds. • A flashing 0 is displayed. • Press or until the password is displayed (Factory setting = 12). If password was changed, select the new password. • Press SEL to confirm password • “0” is displayed. • Press SEL to reset all parameters to factory setting • Press PRG to activate the function and leave the special function mode.

Note: When multiple alarms occur, the highest priority alarm is displayed until being cleared, then the next highest alarm is displayed until all alarms are cleared. Only then will parameters be shown again.

Message --- No data to display

The display will show an “---” at start up and when no data is send to ECD-002

Checking system operating conditions The data to be permanently shown on the display can be selected by the user (parameter 1). It is possible to temporarily display other values. However this function is not available in an alarm condition. The display will show for one

second the numerical identifier of the data (see 1 parameter) and then the selected data. After 5 minutes, the display will return to the value selected by parameter 1.

Service / Troubleshooting Symptom Cause Action

Operating superheat is several degrees higher or lower than set-point

Incorrect signal from pressure or temperature sensors

1- Check the sensors 2- Make sure ECN-N60 temperature sensor is used 3- For optimum accuracy, please use: PT4-07S for R22/R134a/R507/R404A/R407C/R124 PT4-18S for R410A PT4-30S for R744 4- Make sure the sensor cables are not installed along with other

high voltage cables Operating superheat is too low i.e. compressor wet running 1- Incorrect wiring of ECVs

2- Defective sensors 1- Check the wiring 2- Check the sensor

Valve is not fully closed 1- The digital input is ON (24V) 2- Wrong setting of parameter ut.

1- Valve is shut off only when the digital input is turned off (0V) 2- Check the setting of parameter ut

Instable superheat (hunting) Evaporator is designed to operate at higher superheat

Increase the superheat set-point

Valve opens when EC3 commands to close and vice versa Wrong wiring between EC3-X33 and valve

Correct the wiring

EX8 is not able to open at high differential pressure Wrong setting of parameter ut Check the parameter ut. (Larger valve requires higher torque and higher current)

Superheat set-point is shifting after several months of uninterrupted operation or permanent jumper of 24V digital input

Stepper motor driven valves require synchronization

Do not apply permanent 24V digital input. Interrupt digital input once every week for 5 seconds if compressor never stops.

Technical Data Supply voltage : 1N/PE x 230 V - 50 Hz Power input : 320 W Max. switching frequency : 30 / h Dimensions : 220 x 230 x 155 mm (h x ∅) Protective system : IP 68 Weight : approx. 3,5 kg / 4,9 kg Max.water temperature : 1 -35 °C (60 °C short time) Description This manual applies to a Jung Pumpen submersible sump pump U 3 K or U 3 KS with vortex impeller and mounted on level control. Application - The U 3 K/KS pump is designed for usual domestic

waste water. It must not be used for pumping sewage water from lavatories. In some countries sumps with a connection to the public sewer are an explosion hazardous location. For this application the explosion proof UFK series is necessary, for further information ask your distributor.

- Only Ex-approved pumps may be used at different operating conditions in explosion hazardous locations. Please ask the industrial and trade supervision, the building inspection or the employer´s liability insurance association for such an application.

- Allowed temperature of pumped medium: Continuous operation : 35 °C (S1-operation) Intermittent operation : 60°C (S3-operation 40%), 4 min. operation, 6 min. stand by

- The pumps can be used for pumping waste water from dish washers and washing machines.

- If kept dry the pump can be stored down to a minimum temperature of -20°C.

- The flooded pump must not freeze. - Without any additional accessories, a low level

pumping in flooded basements, on flat roofs etc. down to 5 mm water level is possible (see low level pumping).

Transportation and storage The pump can be transported and stored in vertical or horizontal position.

Always use the handle to carry the pump, never lift it at the cable. Make sure the pump cannot roll or fall over and injure people or damage property.

If kept dry the pump can be stored down to a minimum temperature of -20°C. The flooded pump must not freeze. For longer periods of storage, the pump must be protected against moisture and heat. The impeller should be rotated occasionally to prevent the seals from sticking together. After a long period of storage, the pump should be inspected before it is taken into operation. Pay special attention to the seals and the cable gland. Follow the instructions of „Operation“.

Picture 1: dimensions Picture 2: wiring diagram

Do not put the plug into water! Irruption of water may cause malfunctions. Because of the built-in thermostat an additional

motor protection is not necessary. Inadmissible high temperatures and operation times will release the thermostat. If so, pull out the plug before repairs to prevent automatically pump restarts.

Operating Instructions

page 5

Please pay attention to the following regulations at installing the pump(s) or ask your qualified electrician / distributor.

- regulations for electrical installations (in Germany: VDE 0100, VDE 0165)

- regulations for prevention of accidents in sewage technical installations (in Germany: GUV 7.4, GUV 17.6)

- guidelines for explosion protection (in Germany: GUV 19.8)

- electrical installations in explosion hazardous areas (in Germany: Elex V)

Safety precautions In order to minimize the risk of accidents in connection with the service and installation work, the following rules should be followed: - Never work alone. Use a lifting harness, safety line

and a respirator as required. Do not ignore the risk of drowning.

- Make sure there are no poisonous gases within the work area.

- Check the explosion risk before welding or using electric hand tools.

- Do not ignore health hazards. Observe strict cleanliness.

- Bear in mind the risk of electrical accidents. - Make sure that the lifting equipment is in good

condition. - Provide a suitable barrier around the work area,

e.g. guard rail - Make sure you have a clear path of retreat. - Use safety helmet, safety goggles and protective

shoes. - All personnel who work with sewage systems must

be vaccinated against diseases to which they may be exposed.

- A first-aid kit must be close at hand. - Note that special rules apply to installation in

explosive atmosphere. Follow all other health and safety rules and local codes and ordinances Electrical connection

- Following works should only be done by qualified and authorized electricians.

- Jung Pumpen disclaims all responsibility for work done by untrained or/and unauthorized personnel.

- Heed operating voltage ! (see name plate and additional labels)

- Take out the main fuses to isolate the mains supply from the control unit before repairs or any other works and make sure it cannot be energized again.

- If the pump is equipped with automatic level control, there is a risk of sudden restart.

- Before starting check the efficiency of the protective arrangements of the pump and the monitoring equipment. Failure to heed this warning may cause a lethal accident.

- Do not put the lead ends into water! Irruption of water may cause malfunctions.

- If persons are likely to come into physical contact with pump or pumped media, the earthed (grounded) socket must have an additional connection to an earth- (ground) fault protection device (GFI).

- When pumping near a lake, a jetty, a pond etc. a safety distance of at least 20 m between the person and the pump is applicable. Do not place the pump directly in a pool. Observe the special safety regulations if used in connection with swimming pools.

- Use the pump only in accordance to the data stated on the pump´s plate resp. in the technical data on page 4.

Special rules apply to installation in explosive atmosphere. Intrinsically safe circuits (Exi) are normally required for the automatic level control system by level regulators.

- A Jung Pumpen control unit gives you the certainty of design under safety regulations and an acceptance of work without any problems.

- Level sensors must be used at low voltage. For further details please see data sheet / o.m. Local rules may specify otherwise.

- To prevent the pump from blocking after long rest periods an additional daily trial run unit can be installed.

- Connection only to a mains supply installed in accordance to the local regulations. For fusing of d.o.l. starting pumps use only 10 A slow fuses or automatic circuit-breaker with C or D characteristic. (former G and K) Because the motor´s nominal voltage is measured at the terminal board of the pump, please consider the voltage drop of long supply cables.

- The motors of the three-phase a.c. pumps must be protected by a suitable overcurrent release. Adjustment as following: direct start: + 10% of the nominal current star-delta start: (nominal current x 0,58) + 10 % If the protective arrangement has trigged, eliminate the trouble

- Replace the cable if the cable jacket is damaged. Do not pinch the cable or pull it around sharp bends.

- Always install the control unit in a dry and well ventilated room above the backpressure level. Never install the control unit in the sump !

Earthing For safety reasons, the earth conductor should be appr. 50 mm (2 inch) longer than the phase conductors. If the motor cable is jerked loose by mistake, the earth conductor should be at last conductor to come loose from its terminal. This applies to both ends of cable. Ensure the correct earthing of the pump and the control unit.

Installation To ensure the proper installation, consider the dimensions of the installation. The sump has to be cleaned from all sediments before any installation or repair works. The minimum height between the lifting hook and the floor shall be sufficient to lift the pump out of the sump. The lifting equipment shall be able to hoist the pump straight up and down in the sump, preferably without the need for resetting the lifting hook. Oversized lifting equipment could cause damages if the pump should stick when it is lifted. The lifting equipment has to be securely anchored.

Always use the handle to carry the pump, never lift it at the cable or the hose ! To lower the pump in a deep tank, use a rope or a chain.

Climbing pressure pipework has to be installed frost protected.

Stay clear of suspended loads. Take out the main fuses to isolate the mains supply both control unit and pump before any works and make sure it cannot be energized again. Make sure the pump cannot roll or fall over and injure people or damage property. In some installations the water and the pump can be hot. Bear in mind the risk of burn injuries. Before installation, please check: - the visible parts of the pump and the installation - sluice and reflux valves - the oil level in the oil chamber - if the impeller moves freely - direction of rotation The pump should be installed correspondingly to picture 3, 4 or 5. Under DIN EN 12056-2 the pressure tube must be taken in a loop over the local back-up level and secured with a reflux valve. Observe the min. flow speed of 0,7 m/s in the pipework. Stationary installation To remove the pump easily we recommend our guide rail system GR 32, alternatively a flexible connection (min. DN 32/1¼“) in the pressure tube near the pump is conceivable. The connection must be sealed, screwed together and fastened fingertight. To avoid bigger friction losses in long tubes, a correlative bigger pipe diameter is necessary.

Observe the measurements of the float switches as shown in picture 3,4 and 5.

The floats must not be installed below the inlet. The control unit must be installed in well ventilated room above the back pressure level. Mobile operation / deaeration If a flexible hose is connected to the pump, no reflux valve must be installed and the hose must have a gradient to ensure a completely drained off hose when the pump stops working. When the pump is submerged again, water in the hose will prevent the deaeration of the spiral housing and therewith the correct operation of the pump. For the same reason the pump may not operate properly when it is submerged in switched on condition.

Maintenance - Take out the main fuses to isolate the mains

supply of both, control unit and pump, before any works and make sure it cannot be energized again. Check the cable on mechanical or chemical damages. At using a chain to lift the pump, please pay attention to the rules for prevention of accidents. Chains have to be inspected regularly by qualified personal. Only authorised workshops or the manufacturer are permitted to carry out repairs effecting the

electrical security. In case of repairs defective parts must be replaced by genuine spare parts. Jung Pumpen disclaims all responsibility for work done by untrained, unauthorized personnel. General safety - clean the pump thoroughly - beware of the risk of infection - follow local safety regulations The pump is designed for use in liquids which can be dangerous to health. When working on the pump, prevent injuries to the eyes and skin, by: - wearing goggles and rubber gloves - cleaning the pump before any works - cleaning the parts after dismantling - hold a cloth over the drain plug to prevent splatter

when opening the oil chamber In case of contact with dangerous liquids: - eye contact: rinse your eyes immediately in running

water for 15 min. Hold your eyelids apart with your fingers. Contact an eye specialist

- skin contact: remove contaminated clothes, wash your skin with soap and water, seek medical attention, if necessary

To keep the reliability of operation servicing should be made after every 1000 working hours, but not later than once a year. If the pump delivers water with abrassive additions servicing should be carried out at adequate shorter intervals. At decreasing flow rates or ascending noises the impeller has to be checked on wear, and if necessary, it has to be changed.

In case of a damage at the pump a slight quantity of the oil chamber filling can leak into the pumping medium.

Maintenance

In case of repairs or maintenance pull main plug. Check the cable on mechanical or chemical damages.

The foot strainer prevents blockages in the pump, it has to be cleaned regularly as well as the float switch to guarantee the trouble free operation with full performance. In case of blockages take off the wear plate (see whirl system) and remove blocking parts. Other works are not necessary.

Cleaning Regularly cleaning of the impeller and the level control sensors or float switches secures the maximum pumping capacity and operational reliability. Torque ratio MA for screw material: for M 6, MA = 8 Nm (0.8 kpm) for M 8, MA = 20 Nm (2.0 kpm) for M 10, MA = 40 Nm (4.0 kpm) for M 12, MA = 70 Nm (7.0 kpm) for M 16, MA = 160 Nm (16.0 kpm) Installation of flap trap The enclosed rubber flap must be screwed into the discharge branch of the pump casing by using the grooved sheet metal screw. (see pic. 6) If the pump is used in sumps that can dry out, replace the flap trap by a separate reflux valve (e.g. Jung Pumpen swing type check valve No. 9739). The reflux valve should be mounted above the screw fitting. To ensure the correct deaeration of the spiral housing drill a Ø 6 mm hole into the enclosed quarter elbow (part. No. 16687) at the marked position. In contrast to the U 3 KS Niro with built-in level control, the switching points of the U 3 K Niro can be variated if separate float switches are used. Picture 6: deaeration hole

Low level pumping Flooded basements, roofs etc. can easily be drained down to a level of 5 mm with the U 3 K Niro. Put 2 screwdrivers into the „detach slots“ between foot strainer and pump casing and lever down the foot strainer. To ensure the suction of the pump, the hose must be emptied before each pumping sequence and the lowest water level must be 40 mm / 1,6 inch. The built-in level control of the U 3 KS Niro is not working in the low level pumping mode. Whirl system To keep the bottom of the sump in the suction area of the pump largely free of sediments a small modification is necessary. The pump performance will be reduced to 6 m3/h and 6,0 meters of head. Take off the foot strainer as described under shallow pumping. Unscrew the 6 grooved sheet metal screws (part No. 08552) out of the wear plate and take it of. Drill 3 holes with Ø 5 mm into the wear plate as shown on picture 5, remove the burr from the holes and assemble the pump again. The new holes must not be covered from a web of the foot strainer. Picture 7: whirl system Checking of pump unit

Worn out impellers can have sharp edges !

Inspect and adjust the impeller depending on the frequency of operation and the medium being pumped, but not later than half-yearly. At reduced pump performances or increased operational noises the impeller and the pump casing must be checked and replaced if necessary by qualified experts.

Malfunctions Pump does not run cause: missing mains supply remedy: check supply voltage cause: faulty fuse (maybe too low) remedy: check fuse and change if necessary cause: damaged supply cable remedy: changing of the cable gland only by qualified personnel Pump runs, but doesn´t deliver water cause: trapped air in the spiral housing remedy: drain off the pressure tube or hose, to ensure the opening of the reflux valve to deaerate the spiral housing and ensure the correct operation of the pump Blockage of impeller cause: solid- or fibrous admixtures blocking the

impeller remedy: check impeller, as explained under „adjustment of impeller“ or „cleaning“ Reduced performance curve cause: clogged impeller remedy: clean impeller and spiral housing cause: worn-out impeller and / or wear plate remedy: change impeller and / or spiral housing

At replacing the impeller, prevent the bearings against being pushed out of their position, by supporting the upper edge of the motor shaft when pressing on the impeller.

Please pay attention to the following regulations at installing the pump(s) or ask your qualified electrican / distributor.

- regulations for electrical installations EN 60079-14, EN 60079-17, EN 1127-1, GUV-VA2

- regulations for prevention of accidents in sewage technical installations (in Germany: GUV-V C5, GUV-R 126)

- guidelines for explosion protection (in Germany: GUV 19.8, BGR 104, Ex-RL)

- electrical installations in explosion hazardous areas (in Germany: BetrSichV)

Safety precautions In order to minimize the risk of accidents in connection with the service and installation work, the following rules should be followed: - Never work alone. Use a lifting harness, safety line

and a respirator as required. Do not ignore the risk of drowning.

- Make sure there are no poisonous gases within the work area.

- Check the explosion risk before welding or using electric hand tools.

- Do not ignore health hazards. Observe strict cleanliness.

- Bear in mind the risk of electrical accidents. - Make sure that the lifting equipment is in good

condition. - Provide a suitable barrier around the work area,

e.g. guard rail - Make sure you have a clear path of retreat. - Use safety helmet, safety goggles and protective

shoes. - All personnel who work with sewage systems must

be vaccinated against diseases to wich they may be exposed.

- A first-aid kit must be close at hand. - Note that special rules apply to installation in

explosive athmosphere. Follow all other health and safety rules and local codes and ordinances Electrical connection

- The electrical connection should only be done by qualified and authorized electricians.

- Jung Pumpen disclaims all responsibility for work done by untrained or/and unauthorized personnel.

- Heed operating voltage ! (see name plate and additional labels)

- Take out the main fuses to isolate the mains supply from the control unit before repairs or any other works and make sure it cannot be energized again.

- If the pump is equipped with automatic level control, there is a risk of sudden restart.

- Before starting check the efficiency of the protective arrangements of the pump and the monitoring equipment. Failure to heed this warning may cause a lethal accident.

- Do not put the lead ends into water! Irruption of water may cause malfunctions.

- If persons are likely to come into physical contact with pump or pumped media, the earthed (grounded) socket must have an additional connection to a earth- (ground) fault protection device (GFI).

- When pumping near a lake, a jetty, a pond etc. a safety distance of at least 20 m between the person and the pump is applicable. Do not place the pump directly in a pool. Observe the special safety regulations if used in connection with swimming pools.

- Use the pump only in accordance to the data stated on the pump´s plate resp. in the technical data on page 4.

Special rules apply to installation in explosive atmosphere. Intrinsically safe circuits (Exi) are normally required for the automatic level control system by level regulators.

- A Jung Pumpen control unit gives you the certainty of design under safety regulations and an acceptance of work without any problems.

- Level sensors must be used at low voltage. For further details please see data sheet / o.m. Local rules may specify otherwise.

- To prevent the pump from blocking after long rest periods an additional daily trial run unit can be installed.

- Connection only to a mains supply installed in accordance to the local regulations. For fusing of d.o.l. starting pumps use only 10 A slow fuses or automatic circuit-breaker with C or D characteristic. (former G and K) Because the motor´s nominal voltage is measured at the terminal board of the pump, please consider the voltage drop of long supply cables.

- The motors of the three-phase a.c. pumps must be protected by a suitable overcurrent release. Adjustment as following: direct start: of the nominal current star-delta start: nominal current x 0,58 If the protective arrangement has trigged, eliminate the trouble

- Replace the cable if the cable jacket is damaged. Do not pinch the cable or pull it around sharp bends.

- Always install the control unit in a dry and well ventilated room above the backpressure level. Never install the control unit in the sump !

Earthing For safety reasons, the earth conductor should be appr. 50 mm (2 inch) longer than the phase conductors. If the motor cable is jerked loose by mistake, the earth conductor should be at last conductor to come loose from ist terminal. This applies to both ends of cable. Ensure the correct earthing of the pump and the control unit.

Each drain connection (e.g. washing machine, dish washer ...) must have a siphon trap. Installation 1. Remove the tank cover (Pos. No. 2)

(loosen the snap connections on the narrow sides, but do not overstretch). Withdraw the accessories. Screw the pump elbow with sealing tape or a hemp packing on the pump discharge. Do not install the internal pump reflux valve.

2. Push the elastic outlet elbow on the connection branch of the pump, adjust it and tighten it with the hose clamp (Pos.No. 5).

3. Open required connection piece for pressure, inlet (and ventilation) at the marked position, by cutting or drilling. Attention: Do not damage the faying surface ! Push the plug-in seals (Pos.No. 7) into the opened connection branches. If necessary, push the hose connection ∅ 25 with an o-ring seal 40x30 into a lateral connection piece (pic. 4)

4. Put the pump with the outlet elbow into the floor lock of the tank. Push the pressure tube from outside through to the plug-in seal into the elastic outlet elbow (Pos.No. 4) and fix it with a hose clamp (Pos.No. 5). Push the inlet and ventilation pipe about 35 mm into the plug-in seal.

5. Moisten the circular seal (Pos.No. 10) steadily with a slip additive and mount it on the upper edge of the tank. Loosen the screws (Pos.No. 12) of the cover (Pos.No. 3) in the lid. Pull the pump cable with the plug through the hole. After that, push the slotted plug (Pos.No. 11) over the cable and put it back into the hole.

The connection of a shower requires the installation of the special float (code-No. 17424) (pic.5)

Switch heights ON A = 105mm, OFF B = 45mm The cable in the tank must not obstruct the float. Enough cable has to be in the tank to allow the pump to be pulled out of the tank for servicing. 6. Remove and unwrap the activated carbon filter

(Pos.No. 17) and put it over the ventilation hole between the terminal plates (pic. 6). In case of ventilation to the roof press the enclosed plug (Pos.No. 18) into the ventilation hole of the lid (pic. 9).

7. Press the cover (Pos.No. 2) over the tank edge until the snap connections click into place. The O-ring (Pos.No. 10) must lie steadily on the tank edge. The pump cable must be pulled outside and the cover (Pos.No. 3) must be fixed with two screws. Push the two enclosed white caps (Pos.No. 13) on the screws.

Picture 7: Fastening on the wall Picture 8: Change of the activated carbon filter Wall installation If the Hebefix should be mounted on a wall the holes for the suspension can be drilled by using the template printed on the cardboard box. Screw the hook screws (Pos. 14) into the upper holes and fix two rubber bases (Pos. 6) in the lower holes as elastic distance pieces.

Mounting accessories At connecting a shower basin, the pump can only be operated with the special float (code.No. 17424) (pic. 5).

If the inlet in the cover is also used, an elbow must be fixed on the inlet pipe to

prevent the access of air in the spiral housing of the pump. Alarm unit The automatic alarm (code-No. 20198) signalizes an unacceptably high water level. Open the marked position in the cover Ø 13 mm and mount the alarm switch corresponding to the operation instructions. The installation of a U 3 KS or U 6 KS with a low level switch „Duschfix“ requires, the fastener (code-No. 28191) for the alarm unit. Maintenance - Take out the main fuses to isolate the mains

supply of both, control unit and pump, before any works and make sure it cannot be energized again. Check the cable on mechanical or chemical damages. At using a chain to lift the pump, please pay attention to the rules for prevention of accidents. Chains have to be inspected regularly by qualified personal. Only authorized workshops or the manufacturer are permitted to carry out repairs effecting the water tightness.

In case of repairs the gap peripheries have to be inspected for damages, defective parts must be replaced by genuine spare parts. Jung Pumpen disclaims all responsibility for work done by untrained, unauthorized personnel.

General safety - clean the pump thoroughly - beware of the risk of infection - follow local safety regulations The pump is designed for use in liquids which can be dangerous to health. When working on the pump, prevent injuries to the eyes and skin, by: - wearing goggles and rubber gloves - cleaning the pump before any works - cleaning the parts after dismantling - hold a cloth over the drain plug to prevent splatter

when opening the oil chamber In case of contact with dangerous liquids: - eye contact: rinse your eyes immediately in running

water for 15 min. Hold your eyelids apart with your fingers. Contact an eye specialist

- skin contact: remove contaminated clothes, wash your skin with soap and water, seek medical attention, if necessary

To keep the reliability of operation the system should not be inspected later than once a year. If the pump delivers water with abrasive additions servicing should be carried out at adequate shorter intervals. At decreasing flow rates or ascending noises the impeller has to be checked on wear, and if necessary, it has to be changed. Cleaning/ Maintenance Take out the main fuses to isolate the mains supply from the control unit before repairs or any other works and make sure it cannot be energized again. If the pump is equipped with automatic level control, there is a risk of sudden restart. The unit is free of maintenance. In case of a deteriorate pump performance, remove all sediments from the tank. Change of the activated carbon filter - 1x year at least - in case of annoyance caused by bad smell - in case of water penetration through the filter.
