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 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.
3.
To check the refrigerant charge, run the unit for 15 minutes and
briefly remove the evaporator filter 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.
4.
Check all wiring connections.

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.
