ROUTINE SERVICE
To ensure continued full efficiency of the dehumidifier, service procedures
should be performed as follows:
1.
Clean the surface of the evaporator and condenser coils by blowing the
dirt out from behind the fins with compressed air. Hold the nozzle of the
air hose away from the coil to avoid damaging the fins. Alternatively,
vacuum clean the coils.
2.
Check that the fan rotates freely.
The fan motor is sealed for life and
therefore does not need oiling.
3.
To check the refrigerant charge, run the unit for 15 minutes and observe
the evaporator coil. It should be evenly coated with frost across its
surface. At temperatures above 25
°
C, the coil may be covered with
droplets of water rather than frost. Partial frosting accompanied by
frosting of the thin capillary tubes, indicates loss of refrigerant gas or low
charge.
4.
Check all wiring connections, including mains cable for damage or loose
connections.
5.
In order to check the defrost operation, the unit needs to be operated in
an ambient temperature of less than 15°C for at least 1 hour. When
operated In this condition the unit should defrost at least once every
hour. The defrost mode can be monitored by observing the ice melting
on the coil face, prior to defrost the face will show a white coating of
frost, which should clear during defrost
