Areas of application
2.1.1
Application of the heat pump
To prevent unintentional application, which could injure personnel or damage equipment, the following
must be observed:
•
The unit must only be used as a heat pump intended for heating and cooling of water or brine.
•
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 compressor unit
and plant parts caused by torsional oscillation or the like which is attributable to built-in VSD sol-
utions initiated by the customer after delivery.
•
The secondary side on the evaporator and condenser is only intended for water or brine as proc-
ess medium. The secondary medium is stated in the P&I diagram. Deviations are only permitted
with a written permission from Johnson Controls Denmark.
•
Installation of the heat pump/unit in potentially explosive atmospheres must only take place if
the heat pump is fitted with approved explosion-proof equipment.
•
The compressor must only be used as a compressor 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 heat pump of air and moisture
•
To put the heat pump 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 destroy 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.
