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, 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
