ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN

DISCONNECTED BEFORE CARRYING OUT ROUTINE

To ensure continued full efficiency of the dehumidifier, maintenance

procedures should be performed as follows:

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.

DO NOT STEAM CLEAN REFRIGERATION COILS

Check that the fan rotates freely. The fan motor is sealed for life

and therefore does not need oiling.

To check the refrigerant charge, run the unit for 15 minutes and

briefly remove the top cover. The evaporator coil should be evenly

frost coated across its surface. At temperatures above 80°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.

Check all wiring connections.

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
