OPERATION
The following procedures should be followed to test the WM80 for correct
operation:
1. After unpacking, examine all external features to confirm damage-
free shipment. Report all defects and damage at once. Connect the
power cable to a grounded 13 Amp electrical socket. Connect the
drainage outlet to a suitably sized hose and run the hose to a
permanent drain.
2. Check dehumidification process as follows:
a. Place unit on a level surface.
b. Start up unit by switching to “ON” and turning the humidistat
clockwise.
c. Check that the compressor is running.
d. Leave the machine running for 15 minutes.
e. Observe the evaporator coils through the rear upper grille, to
confirm frost formation.
f. If the air temperature is below 25ºC, an even coating of frost
should cover the entire evaporator coil.
g. If the air temperature is above 25°C, frost and/or droplets of
condensed water should cover the entire evaporator coil.
h. After continuous running time of approximately 55 minutes, unit
will enter “Hot Gas” defrost mode for several minutes and then
automatically return to normal operation.
If, after carrying out the above procedures, the unit does not appear
to function properly, refer to the Trouble Shooting section, which
follows, or contact the Factory Service Center.
After using the WM80, turn it off for five minutes to allow the
condensate on the coils to drain into the pump reservoir.
