ROUTINE SERVICE
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. Remove the air filter and clean by either blowing compressed air
through, vacuuming or washing in warm water
3. Check that the fan is firmly secured to the motor shaft and that the
fan rotates freely. The fan motor is sealed for life and therefore
does not need oiling.
4. 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 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. During this inspection, check
visually to ensure that the pump rollers are turning.
5. Check all wiring connections.
6. To check the operation of the defrost system, switch the machine on
and leave it running for approximately 55 minutes. The machine will
then enter “Hot Gas” defrost mode for approximately 5 minutes
before returning to normal operation. If the unit will not defrost, the
printed circuit timer board may be defective or the by-pass valve may
be inoperable.
