5.8 Cooling circuit
The following steps should be taken to maintain the evaporator and condenser coil of the
cooling circuit:
•
Check the coils for dust or dirt. If necessary, clean the aluminium fins by a soft brush
or a vacuum cleaner.
•
Straighten any bent slats using appropriate tools.
The following steps should be taken to check the cooling circuit:
•
Close all inspection doors and start up the unit. Wait for a few minutes and check the
LP/HP gauges. The HP gauge should show between 35-50 °C and the LP gauge
about 5-10°C, depending on the running and outside conditions.
•
Keep the unit running, open the inspection door by the receiver and check if there is
enough refrigerant in the receiver and if the sight glass of the refrigerant circuit is free
of bubbles.
If you are in doubt about the condition of the cooling circuit, stop the compressor at once to
avoid damage and call a cooling technician or the Dantherm service.
