Areas of application
2.1.1
Application
To prevent unintentional application which could injure personnel or damage equipment, the fol-
lowing must be observed:
•
The unit must only be used as a liquid refrigeration unit intended for water or brine
cooling.
•
The unit must not be installed in areas where the relative humidity (RH) may exceed 85%
(95% if the motor is made for 100% RH).
•
The primary side must only be charged with refrigerant R717.
•
Johnson Controls Denmark further accept no liability of any kind for damage to compres-
sor unit and plant parts caused by torsional oscillation or the like which is attributable to
built-in VSD solutions initiated by the customer after delivery.
•
The secondary side on the evaporator and condenser is only intended for water or brine as
cooling medium. The secondary medium is stated on the P&I diagram. Deviations are only
permitted with a written permission from Johnson Controls Denmark.
•
Installation of the chiller in potentially explosive atmospheres must only take place if the
chiller is fitted with approved explosion-proof equipment.
•
The compressor must only be used as a refrigeration compressor and within the operating
limits specified in the manual or in a written agreement with Johnson Controls Denmark.
•
The compressor must only be used with the number of revolutions per minute, as shown
on the compressor name plate.
The compressor must NOT be used:
•
To evacuate the refrigeration plant of air and moisture.
•
To put the refrigeration plant under air pressure in view of a pressure testing.
•
As an air compressor.
2.1.2
Application of combustion engines
According to EN 378/ISO 5149, no other machinery should be installed in a refrigeration machine
room. Some refrigerant types may, to a certain extent, be absorbed by the fuel in a combustion
engine, and when the contaminated fuel reaches the fuel pumps, the refrigerant will “flash out”
(separate) and react on the increased temperature and pressure by creating acids, which will de-
stroy the pumps. However, check with the local authorities as exemptions to this rule may be
granted.
Warning!
Johnson Controls Denmark is not liable for injuries to personnel or damage to equipment resulting
from using the equipment for other purposes than the ones stated above.
