INTRODUCTION
Designed for a wide range of applications, the WM80 is a rugged, industrial
unit, which utilizes an energy-efficient compressor and a compact portable
design to provide easy efficient drying.
The WM80 has a number of special features:
•
High efficiency rotary compressor
•
Ebac’s “Hot Gas” defrost system
•
Integral pump out system
•
Provision for permanent drainage
•
Exterior epoxy powder-coated finish
•
Extra long power cord
•
Free Standing or Wall Mountable
•
Status Indicators
•
Control Humidistat
The fan draws the moist air through the cold evaporator coil, which cools the
air below its dew point. Moisture forms on the evaporator coil and is collected
in the condensate tray, which is equipped with a permanent drain. The cooled
air then passes through the hot condenser coil where it is reheated using the
same energy removed during the cooling phase, plus the additional heat
generated by the compressor. The air is, therefore, discharged from the
dehumidifier at a slightly higher temperature with a lower absolute humidity
than that which entered. Continuous circulation of air through the
dehumidifier gradually reduces the relative humidity within the area.
The WM80 dehumidifier is a reliable drying unit designed to operate
effectively over a broad range of temperature and humidity conditions. An
active hot gas defrost system, controlled by an electronic timer, guarantees
positive de-icing, thereby optimizing operation at low temperatures.

OPERATION
The following procedures should be followed to test the WM80 for correct
operation:
1. After unpacking, examine all external features to confirm damagefree shipment. Report all defects and damage at once. Connect the
power cable to a grounded 13 Amp electrical socket
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.
ONCE THE UNIT HAS BEEN SWITCHED OFF, WAIT AT
LEAST FIVE MINUTES BEFORE RESTARTING.
After using the WM80, turn it off for five minutes to allow the
condensate on the coils to drain into the pump reservoir.
