HYDRAULIC CONNECTIONS

You are recommended to install the following instruments on the evaporator water circuit:1. Two pressure gauges with appropriate scale (on inlet and outlet)2. Two vibration damping couplings (on inlet and outlet)3. Two gate valves (normal on inlet, adjusting on outlet)4. One flow switch (on inlet)5. Two thermometers (on inlet and outlet)6. One inlet filter positioned as close as possible to the evaporatorThe water flow rate to the refrigerating unit must be within the range of values shown.The water flow rate mustbe kept constant during operation.The water content of the system must be such as to avoid unbalanced operation of the chilling circuits. Refer tothe values shown.If there are two parallel units on the same water circuit, the minimum content of the system will be equal to the

sum of the minimum content of the individual units.

FANS

IMPORTANT- The duct must be insulated to avoid the formation of condensation.- Fit an anti-vibration coupling between the air outlet and the duct.- If the units are ducted, remove the “V” element (flow rate limiter) on the air outlet..- An incorrectly dimensioned duct may cause the unit to shut down.

The units can operate with the air outlet either free or ducted.Air may be expelled frontwards, upwards or laterally to the left (see dimensioned drawings).The curves given onpages 10 and 11 indicate useful fan pressure to allow correct dimensioning of the air outlet ducts.

FUNCTIONAL ELECTRICAL CONNECTIONS

IMPORTANT:- Power up the unit only when both hydraulic and electrical installation has been completed;- Carry out all electrical connections as laid down by the relevant regulations current in the destination

country;- Comply with the instructions on live, neutral and earth lead connections;- Ensure that the power line upstream of the unit is equipped with adequate protection against short-circuits

to cut the system off from other power users;- Voltage values must never exceed tolerances of ±10% of the unit’s rated supply voltage.

If these parameters are exceeded, contact your local electricity company.

ACCESSING THE SWITCHBOARD AND ELECTRICAL/ELECTRONIC COMPONENTSRemove the panel to the right of the plate heat exchanger by unscrewing the four or more screws, gripping thehandle and pulling it downwards. Removing the front panel allows access to the disconnector switch and thecontrol keyboard. For access to the interior of the switchboard, position the disconnector switch to OFF andunscrew the fixing screws.

CHECKING AND STARTING THE UNIT

IMPORTANT:- Before starting the unit, check it as indicated in the relevant paragraph;- The technical support centre (if its presence is specified in the sale contract) will not start up the machine if

the installer has not carried out all the checks and inspections described below:- Power up the unit only after completing the checks.

CHECKING THE HYDRAULIC CIRCUIT- Fill the hydraulic circuit and bring it up to pressure;- Ensure there is no air in the circuit; if necessary bleed air using the air vent valves;- Ensure that the temperature of the fluid does not exceed the unit operating range;- Check operation of unit circulating pump by turning on separately;- Ensure all gate valves are open;- Check water flow to the plate heat exchangers.

CHECKING THE ELECTRICAL CIRCUIT- Voltage should be within a tolerance of 10% of the unit’s rated supply voltage: 230 ±10% / 400 ±10%;- Inspect power supply lead connections;- Inspect earthing connections;- Inspect the connections of the safety devices installed in the hydraulic circuit;- Inspect remote control and remote keyboard kit connections (if installed);- Check that the condenser fans are connected to the unit switchboard or the mains power supply.

IMPORTANT:- Initial start-up must take place using the standard settings; you should change the operating set point values

only after having tested the unit;- Before starting, power up the unit for at least eight hours with the magneto-thermal switch in the ON

position in order to allow the compressor sump oil to heat up.

STARTING THE UNITPosition the magneto-thermal switch QF and the door lock disconnector switch in the ON position.Turn the unit on using the ON/OFF button on the keyboard.Choose the chill/heat mode of operation with the MODE key on the keyboard.Wait for the compressor delay period (compressor LED 1 flashing).

IMPORTANT:If the following should be displayed during this initial phase, proceed as follows:- E00 check the connections to terminals 21 and 22.- E41 check water flow rate and flow meter connection (flow meter not included)

CHECKING THE COMPRESSOR (IN OPERATION)Check that the noise level of the compressor does not exceed the normal value and that compressor outputpressure is greater than input pressure. If these conditions are not respected check the sequence of powersupply lead phase connections L1-L2-L3 (incorrect rotation direction).Ensure that the voltage value is within the established limits and that the unbalance between the three phases(three-phase voltage) does not exceed 3%. Check that compressor current absorption is lower than the valuesshown in the Electrical Data table.

06/98 11Sect.2/MT

CHECKING AIR FLOW RATECheck the air flow rate is within the limits indicated in the fan performance tables.

CHECKING THE HYDRAULIC CIRCUITCheck the water flow rate through the difference in temperature between plate exchanger input and output water:Q [l/h\ = (kWx860)/∆TQ : water flow ratekW : output power with reference to unit operating conditions∆T : difference in temperature between plate exchanger input and output water

∆T < 5°C implies a flow rate higher than the rated value∆T > 5°C implies a flow rate lower than the rated valueUnits are designed to have a ∆T of 5°C for proper operation.

FILLING OUT THE MACHINE LOGBOOKWhen you have completed all tests fill out the machine logbook with all the required information together withthe warranty which must be sent to our After-Sales Service within 7 days of commissioning the unit. Failure tocompile the machine logbook and warranty invalidates the warranty immediately.

DISPLAYING ALARMS

IMPORTANT:- Before resetting the unit, remove the cause of the malfunction; failure to do so will invalidate the warranty

immediately- If the same malfunction occurs again, call the specialist maintenance company.

Unit operation is controlled by a microprocessor that also triggers a series of alarms.When an alarm is triggered, acode will flash on the keyboard values display.The table below shows the various error conditions indicated by the alarm.

OPERATING CHARACTERISTICS

START-UP AND SHUT-DOWNStart up and shut down the unit using the QS door lock disconnector switch.This supplies power to the compressor sump heater and the electronic board in stand-by.To start the unit set the required mode on the keyboard (chill/heat) with the ON/OFF and MODE keys.Compressor operation is regulated by the temperature of water coming from the plate exchanger.

For example: Chill Set Point (factory-set) = 13.5°C, hysteresis = +- 1.5°CCompressor starts if water temperature exceeds 13.5°C + 1.5°C (15°C)Compressor switches off if water temperature is below 13.5°C - 1.5°C (12°C)

For example: Heat Set Point (factory-set) = 43.5°C, hysteresis = +- 1.5°CCompressor starts if water temperature drops below 43.5°C + 1.5°C (42.0 °C)Compressor switches off if water temperature exceeds 43.5°C - 1.5°C (45°C)

When you restore power to the unit after a brief interruption, the mode set is retained in the memory.

COMPRESSOR START-UP DELAYTo prevent compressor restarts too close to one another, a special function has been provided to prevent thecompressor being restarted unless a given time has elapsed since the last switch-off.The function also defines amaximum number of restarts possible in one hour.

CIRCULATING PUMPThe electronic board has only one output to control the circulating pump.This is activated 30 seconds beforecompressor start-up and is turned off 120 seconds after compressor shut-down.After the first 25 seconds of pump operation when the water flow rate is steady, the water flow rate alarmfunctions are enabled (differential pressure switch and flow switch if installed).

FAN SPEED REGULATIONTo enable the unit to operate correctly in various external temperatures, the microprocessor with pressurereading via the transducer controls the fan speed module, thus enabling thermal exchange to be increasedand/or reduced while maintaining condensation or evaporation pressures more or less constant.

DEFROSTINGDuring operation in heating mode with extremely cold temperatures or high relative humidity, ice may form onthe external water coil. If allowed to build up, this would considerably reduce unit efficency. To avoid this, areverse operation function allows ice on the coil to be removed.This function has two phases:- when evaporation pressure drops below the value set in the factory, the microprocessor calculates a preset

time after which defrosting commences. If during that preset time, the pressure exceeds the value set in thefactory, the microprocessor cancels the countdown initiated;

- cycle reversal lasts until condensation pressure exceeds a set value or a predefined period of time has passed.

FROST PROTECTION ALARMTo prevent damage to the plate exchanger due to the internal formation of ice, the microprocessor shuts downthe compressor if the temperature measured by the exchanger outlet temperature sensor is less than +3°C.This frost protection set point temperature can only be changed by a specialist company and only after havingchecked that the water circuit contains an anti-freeze solution.

WATER FLOW RATE ALARMThe microprocessor includes an alarm triggered by water flow rate outside the unit: the flow switch.This type of safety device may be triggered after the first 25 seconds of pump operation when the water flowrate is steady.The alarm shuts down the compressor but not the pump which remains active for some time.To resume normal operation, the alarm contact must be deactivated for at least 5 seconds.

MAINTENANCE

CLEANING THE COIL AND FILTERClean the surface of the coil with a brush and air jet to remove impuritites. If installed, clean the filter withwater or air jet.Check that the aluminium fins on the coil are not bent or in a position which prevents normal air flow. If bent,straighten with special comb.

FANSCheck the fixing of fans and mounts in order to eliminate the transfer of vibration to the structure.

HYDRAULIC CIRCUITWhen you start up the unit after a period of inactivity, check the pump for correct operation. If the impeller isjammed, release it by removing the screw on the pump head and rotating the impeller with a screwdriver.Be sure there are no leaks in the water circuit.Check the water flow rate by measuring the ∆T at exchanger inlet and outlet.Clean the water filter installed in the water mains.

ELECTRICAL CIRCUITInspect the unit power supply cables.Check that the connection clamps of power and signal interface cables are tight (this should be done by aspecialist maintenance company).Ensure voltage values are within the values recommended by the manufacturer.

CHECKING FUNCTIONS AND ALARMS (FOR SPECIALIST COMPANY ONLY)Check that the pressure transducer reading matches the pressure measured by the gauge; if necessary, adjust.Check that the temperature sensor reading matches the thermometer reading; if necessary, adjust.Check flow switch operation.Check operation of the differential pressure and flow switchs (if installed) by closing the hydraulic circuit gatevalves.Via the chiller circuit liquid flow indicator light, check that no coolant is flowing in a gaseous state.

IMPORTANT:- before carrying out maintenance on the unit, disconnect from the power supply;- constant cleaning of the air filter (optional) and coil ensures correct unit operation;- you are recommended to check all unit functions at the start of each season and have the unit checked at

least once a year by an authorised service centre.
