1.3 Safety instructions for coolant
Danger specications:
The R410A coolant is classied as a chemical with low toxicity. The maximum workplace concentration (MAK value)
should not exceed the following limit values:
Diuormethane CH2F2 and pentauorethane 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 ames
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 re 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 rst 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 articially 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 oor 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.

Operating Manual SunCool for SUNTEST® CPS+
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 liqueer
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 sufcient ventilation
facilities near the oor. The doors of the room must have
ventilation slits near to the oor.
3.3 Installation
• Evaporator dimensions (W x D x H):
35 cm x 32 cm x 33 cm
• Evaporator weight: approx. 7 kg
• Liqueer unit dimensions (W x D x H):
70 cm x 60 cm x 35 cm
• Liqueer unit weight: 30 kg
• Place the evaporator unit on a stable laboratory bench
with a non-ammable 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 cm
Rear: 50 cm

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 ames 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.

Operating Manual SunCool for SUNTEST® CPS+
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

5.2 Setting the test parameters
The minimum test chamber temperature (CHT) and black
standard temperature (BST) in the SUNTEST are directly
dependent on the ambient temperature. The higher the
ambient temperature, the higher the blow-in temperature
of the chiller and, as a result, the minimum CHT and BST.
The diagram below (Fig. 4) shows the approximately
achievable test chamber and black standard temperatures.
