ROUTINE MAINTENANCE
WARNING:
ENSURE THAT THE POWER CORD TO THE MACHINE
HAS BEEN DISCONNECTED BEFORE CARRYING OUT
ROUTINE MAINTENANCE ON ITEMS 1, 2, 4, 5, AND 6.
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 (approx 6”) to avoid damaging the fins. Alternatively, vacuum clean the coils.
WARNING:
DO NOT STEAM CLEAN REFRIGERATION 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
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.
4.
Check all wiring connections.
5. To check the operation of the defrost system, switch the machine on and leave it
running for approximately 45 minutes. The machine will then enter “Hot Gas”
defrost mode for approximately 4 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.
