Routine Service - EIP Ebac WM150 Owner's Manual

ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN DISCONNECTED BEFORE
CARRYING OUT ROUTINE SERVICE. THE SERVICING AND REPAIR OF THIS UNIT SHOULD
ONLY BE CARRIED OUT BY A SUITABLY QUALIFIED PERSON.
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.
WARNING: DO NOT STEAM CLEAN REFRIGERATION
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 42 minutes. The machine will then enter
"Reverse Cycle" 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.
