ROUTINE MAINTENANCE
To ensure continued full efficiency of the dehumidifier, maintenance
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 remove the front cover, run the unit for
15 minutes and observe the evaporator coil. It should be evenly frost
coated across its surface. At temperatures above 78
°
F, 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.
5. In order to check the defrost operation, the unit needs to be operated in
an ambient temperature of less than 59°F for at least 1 hour. When
operated In this condition the unit should defrost at least once 20 mins.
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
