- 10 -


1.3 Safety instructions for coolant

Danger specifications:The R410A coolant is classified as a chemical with low toxicity. The maximum workplace concentration (MAK value) should not exceed the following limit values:

Difluormethane CH2F2 and pentafluorethane C2HF5: max. 1000 ppm and 3500 mg/cm³.

Handling of R410A may be dangerous in the case of:• Direct contact with the skin • Prolonged inhalation of coolant fumes • Reaction of the chemical with intense heat and open flames

CAUTION – danger of burns!

Escaping coolant cools down rapidly. Contact with the R410A can lead to cold burns and frostbite. Protective overalls, gloves, face mask and glasses must be worn for all work on the chiller.

WARNING – Intoxication

If large amounts of R410A escape into the room atmosphere, fumes are produced that can lead to intoxication or disturbance of the heart rate which could be fatal. Take immediate safety precautions in case of heavy leakage from the coolant circuit.• Air the room immediately, if safe to do so • Leave the room and secure the entrances to prevent anyone else from entering the room • Post signs alerting people to the possible danger of fumes! • Inform the safety service or fire department!

CAUTION – dangerous chemical reactions!

R410A reacts with open lights or when in contact with very hot surfaces and will produce toxic or irritative substances.Do not use open lights in the vicinity of the SunCool! Do not expose the SunCool to excessive heat!

1.3 Safety instructions for coolant

First aid measures:The first aid measure is only an emergency measure or immediate help in the case of minor injuries; Victims should be placed in a stable side position in case of unconsciousness.

A physician should always be consulted in case of prolonged contact with the coolant. Inform the physician that the injured person was exposed to R410A coolant (the physician may not administer any drugs of the adrenaline-ephedrine group).

Contaminated clothing: Remove contaminated clothing immediately if they are not stuck to the skin. Clothing which is stuck to the skin may only be removed under medical supervision.

Skin contact with the coolant:Thaw out contact points (burns) on the skin. Wash the affected area of the skin with generous amounts of warm water.

Retina contact with the coolant:Rinse eye carefully with large amounts of water. Keep eyelids open for at least 10 minutes. Consult a physician.

Inhalation of coolant fumes:Inform an emergency doctor immediately. Get the victim into a well-heated room and supply with fresh air; have a trained person treat the victim with oxygen if he has inhaled large amounts of fumes. In case of intoxication symptoms have a trained person respirate artificially or with oxygen and apply heart massage.

Ingestion of coolant:If the victim is conscious, rinse out their mouth and throat and give them water or a warm drink.Inform an emergency doctor immediately. Get the victim into a stable side position to reduce the risk of vomiting. Do not induce vomiting.

Clearing up small amounts of R410A:Put on protective clothing and seal the leak in the coolant circuit if possible. Escaping coolant turns into a gas which gathers near the floor as it is heavier than air. Therefore, ventilate the operations room well. Open several doors or exits to the outside if possible to create a draft.

- 13 -


3Requirements for the installation site

3.1 Room climate

Climatic requirements for the operating room:In continuous operation together with the SUNTEST CPS+ there is a constant change in the room climate due to the hot air emitted by the radiator cooling and the liquefier unit as well as the cold air emitted by the evaporator unit. Therefore, the device may only be installed in adequately aired, dust-free rooms or must be connected to a suitable technical ventilation unit.Ambient conditions:• Room temperatures of 18 °C to 25 °C • Relative humidity of 50% max.

3.2 Room ventilation

The coolant is processed in the cooling system in different aggregate states. The coolant is heavier than air in vapor form. The room must therefore have sufficient ventilation facilities near the floor. The doors of the room must have ventilation slits near to the floor.

3.3 Installation

• Evaporator dimensions (W x D x H): 35 cm x 32 cm x 33 cm• Evaporator weight: approx. 7 kg• Liquefier unit dimensions (W x D x H): 70 cm x 60 cm x 35 cm• Liquefier unit weight: 30 kg• Place the evaporator unit on a stable laboratory bench

with a non-flammable surface and align the lab bench horizontally

NOTE –

minimum load capacity of the lab bench

The total dead weight of the SUNTEST® CPS+ and a SunCool is approx. 40 kg. Please note the minimum load capacity of your lab bench.

CAUTION – overheating of the device!

If the air feed and discharge (of the SUNTEST CPS+) is disturbed, the device overheats and can be damaged! Keep the following minimum distances from adjacent walls or objects when installing:

Front: 70 cmRear: 50 cmTop: 70 cmSides: 50 cm


- 14 -

3.5 Transport

NOTE – Transport!

The instrument may only be transported by experienced service personnel who have suitable tools.

3.6 Effects of vibrations

The compressor produces vibrations during the refriger-ant liquefaction process. The refrigeration device should therefore not be set up near machinery or equipment that is sensitive to vibrations.

3.4 Heat sources

Heat sources employing open flames or which utilize extremely hot surfaces may not be employed to heat the installation area.

CAUTION – dangerous chemical reactions!

Leaking coolant can produce toxic or irritant substances in reaction with open lights or hot surfaces.

The SunCool should not be installed in the immediate vicinity of heat sources or exposed to direct sunlight be-cause the energy consumption of the cooling system is increased by the effect of heat.

5.1 SunCool functionality

The SunCool unit allows the Suntest® CPS+ instrument to supply cooled air to the test chamber. To do this, the evaporator unit 2 (Fig. 3, page 16) takes in room air and feeds it into the test chamber at the temperature reduced by the heat exchanger.

NOTE – freezing!

Freezing is improbable in the system butplease contact your technical service representative in the event that it does occur. The SunCool instrument is switched off by a thermostat to avoid freezing and switches back on after thawing. The values for the test chamber temperature may therefore deviate from the set values during freezing. Fig. 4

6.4 Closing the coolant circuit

Connecting the condensation drain of the evaporator unit (Fig. 6.1):The condensation produced in the evaporator unit in the heat exchanger is discharged at the drain spout 1.The condensation can be collected in a waste water tank 3 via a hose connection 2. Alternatively, the conden-sation drain can be connected to a sewer drain on site.This is provided that the evaporator unit is installed at a height which allows drainage by gravity.

Connecting the waste water pump (Fig. 6.2):If it is necessary to pump off the condensation, a micro pump (delivery volume 12 l/h) can be connected between the connection spouts and the drain hose. The micro-pump is equipped with an internal floating contact and only switches on when there is a sufficient amount of condensation.1. Connect the micro-pump 2 to the hose nozzle of the

evaporator unit with the length of hose 1 provided.2. Lay the drain hose 3 of the micro-pump into the sewer

drain or waste water tank.3. Insert the plug 4 of the micro-pump into a properly

grounded and fused receptacle.4. Make sure that no tensile and tractive forces act on

the power cable.


Touching live parts can lead to life threatening electrical shock.Check plugs and power cables of the micro-pump for damage before connecting to the main power supply.Damaged parts must not be used for main power supply connection!

The liquefier unit can be installed separately on the floor or in combination with the SUNTEST® CPS+ on a workbench or sub frame with shelves. If the equipment is placed on a device, no other equipment which is sensitive to vibrations should be placed on this surface. The compressor of the liquefier unit vibrates during liquefaction of the coolant and could have a damaging effect on equipment which is sensitive to vibrations.

NOTE – condensation

Colder indoor temperatures may result in small amounts of condensation on the liquefier unit when the chiller starts. Please bare in mind when choosing the installation site that dripping condensation can cause damage. The SUNTEST CPS+ and the evaporator trough should, therefore, always be placed on a surface above the liquefier unit.

Installing the liquefier unit (Fig. 6.3)1. Install the SUNTEST CPS+ instrument 2.2. Install the liquefier unit 5 of the chiller, taking into

account that the length of the hose/cable connections 4 to the evaporator unit 1 is 2.5 m. Assure proper distances are kept from adjacent surfaces as noted in Figure 3. Align the liquefier unit horizontally and check the stability of the unit.

3. Remove the filter mat 3 from the air inlet aperture on the SUNTEST instrument. Position the evaporator unit of the chiller close to the air inlet aperture of the weathering instrument. The instrument connection requires no other connecting elements.

4. Lay the hose connections 4 between the units so that a bending radius of at least 20 cm is kept at bends.

5. Make sure that the hoses or connecting cables are not exposed to tensile or tractive forces.

NOTE – return coolant

If the liquefier unit was tilted or turned upside down during transport or installation, it must remain in its correct posi-tion for two hours prior to starting the cooler to allow the coolant to collect completely in the liquefier unit.

6.6 Outdoor installation of the liquefier unit

NOTE – installation work

The outdoor installation of the liquefier unit, the position-ing of supply and return cables for the coolant and the positioning of the power and connecting cables should only be performed by authorized and qualified cooling and air conditioning technicians and electricians!

WARNING – malfunction!

When installing outdoors, the chiller connec-tion must be protected from rain and splash-ing water to avoid malfunctions or electrical shocks!

Assembly position:In outdoor installation, the liquefier unit should be mounted in a place protected from the sun and rain. For protection against collecting water or snow, the mounting position should be approx. 20 to 30 cm above the ground or the floor or the liquefier unit should be placed on an appro-priately high base. The safety distances (chap. 3.7) from adjacent surfaces should be maintained on all sides.

Condensation forms when operating the liquefier unit at cold outdoor temperatures. Therefore, an appropriate as-sembly position must be utilized in order to avoid dripping condensation causing damage.The difference in height between the assembly position of the liquefier unit and the installation site of the evaporator unit/SUNTEST instrument should not exceed 5 m. See section 6.4 for installation of these units.

NOTE – winter operation

The liquefier unit is equipped with a winter control; no additional condensation pressure regulation is required for outdoor installation.

Pipe material (Fig. 6.4): For outdoor installation, the supply and return pipes (see fig. 6.4) must be installed using flexible copper pipe de-signed for the transfer of refrigerant. The pipe should not exceed a maximum length of 15 m. Under no circum-stances should the enclosed standard hose connections be used. Supply and return pipes should be installed with as few bends as possible; the inside diameter of the pipes must not be compromised by crushed pipe material when laying bends. Then bending radius must be at least 20 cm.

WARNING – danger of intoxication!

If large amounts of R410A escape into the room atmosphere, fumes are produced which can lead to intoxication or irregular heartbeat which could be fatal. Take immediate safety precautions in case of heavy leakage from the coolant circuit!

Pipe connections (liquefier unit): The pipe connections on the liquefier unit consist of two valves 1 and 2 (see fig. 6.5). The valve 2 of the sup-ply line has an additional maintenance connection 6 with Schrader valve. The pipes 3 to be laid by the customer must be fitted with a union nut 4 and equipped with a flanged end 5.

NOTE – nature of the flanged end!

The wall length of the socket should be evenly flanged. Make sure that no chips, dust or other foreign bodies fall inside the pipes because the coolant circuit could otherwise be blocked at the level of the hair pipe. This would result in blockage of the system or seizing of the compressor of the liquefier unit.

Coolant volume: The coolant volume of 1050 g is sufficient to supply a piping system (supply and return line) of a total length of 10 m. If the piping system exceeds this dimension, an additional 15 g of coolant (R410A) for every further meter of pipe laid must be added into the circuit. The coolant is added at the maintenance connection 6 through the Schrader valve.

Checking for leaks:To check for leaks, pressure is applied to the supply line (liquid gas pipe) and to the return line (suction gas pipe) for approx. 30 minutes.

NOTE – closing state of the valves!

To check for leaks, the stop taps of the valves on the liquefier unit must not be open (see Fig. 6.5, Page 23):1. Connect pipes to the valves of the liquefier unit and

the pipe with the quick-release couplings. 2. Connect the vacuum pump to the maintenance aperture 6 of the return valve of the liquefier unit.

3. Drain the pipes empty until an absolute pressure of 0.1 bar is reached.

4. Switch off the vacuum pump. Measure the pressure again after 30 minutes. The pipe must hold a constant pressure of 0.1 bar.

5. Remove the connecting hose of the vacuum pump from the maintenance aperture of the stop tap and seal the maintenance aperture with the stopper 7.

Opening the coolant circuit (Fig. 6.6): 1. Unscrew the stoppers 1 and 4 from the valves. 2. Fully open the stop taps 3 and 5 of the two valves

with the allen wrench 2. Turn the stop tap carefully counterclockwise to the stop.

3. Unscrew the stoppers 1 and 4 on the valves and tighten until the torque increases. Then tighten the stopper by a quarter turn.

NOTE – leak test!

After the tightness test and opening of the coolant circuit, the entire pipe system must be checked for leaks with a leak tester.

Checking the fill volume of the coolant:The inspection can be carried out with a portable pressure gauge for freon with a pressurized connection of ¼ SAE. The vacuum pump is connected to the valve‘s maintenance connection. The read pressure must correspond to the saturation pressure of the respective room temperature (20 °C = 14.4 bar / 0 °C = 7.98 bar).

6.7 Main power supply


Touching live parts can lead to life threaten-ing electrical shocks. Check plugs and power cables for damage before connecting to the main power supply. Damaged parts may not be used for electrical connection!

Connecting interface cables (Fig. 6.7):The liquefier unit and SUNTEST CPS+ are connected by the interface cable (4-pin plug coupling).1. Insert the plug coupling 3 with the union nut into the

receptacle 2 on the back of the SUNTEST CPS+ and secure with the union nut.

2. Make sure that the interface cable is not subject to excessive stress or strain.

Connecting SunCool (Fig. 6.7):1. Before connecting to the main power supply, check

whether the values of the power supply network of the room of installation match the data on the rating plate on the back of the instrument.

2. If the data for voltage (V) and maximum current (A) do not match, the instrument should not be connected.

3. Plug one end of the PE contact plug 1 (on the instru-ment side) into the light equipment socket and the other end into a properly grounded and fused socket. The SunCool instrument will then be ready for operation and the cooling process can begin.

4. Make sure that no tensile or tractive forces act on the power cables.

CAUTION – outdoor installation!

In case of outdoor installation of the liquefier unit, the light equipment plug connection must be protected against rain and splashing water.

7Operation

7.3 Starting the cooling process

A short safety check must be performed on the chiller every time it is started:• Check whether the coolant hoses have been installed

with sufficient bending radius and are not kinked.• Check whether the coolant is leaking from the coolant

hoses or the instrument connections.• Make sure that the condensation drain of the evaporator

unit is fed into a sewer drain or waste water tank.

NOTE – delayed cooling start

The cooling process does not start until shortly after swit-ching on the chiller. If this start delay should present a problem for any temperature-sensitive samples, a delayed program start can be selected in the instrument control of the test instrument.

NOTE – software documentation

The operation of the instrument control and the program-ming of the test programs are explained in the separate software documentation manual.

NOTE – air temperature (Fig. 7)

Constantly cooled air is fed into the test chamber. By altering the distance between the evaporator unit and the air inlet aperture of the SUNTEST CPS+, the air tempe-rature can be adjusted upwards. Since the temperature value depends on the climatic conditions of the room of installation, the alteration value of the air temperature must be determined by experimentation. However, in order to achieve full cooling power, the evaporator unit must be placed directly in contact with the SUNTEST CPS+ unit.
