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.

INSTALLATION

The WM80 Dehumidifier can be left free standing unit, alternatively can be
wall mounted for instructions on mounting the unit please read the following:

A full installation kit is included in the package to allow a problem free install.
This kit comprises of the following :-

1 X WM80 Dehumidifier
1 X Mounting Bracket
4 X Rawl plugs and screws
4 X M6 Hex Head Bolts, flat and spring washers

For mounting the WM80 Dehumidifier to a wall you will first need to remove
the cover from the unit and detach the wall mounting bracket from the rear of
the unit by removing the 4 bolts that secures it.

With reference to the installation drawing at the rear of this manual, maintain
the minimum clearances from adjacent objects (ie walls celings etc).
Maintaining these distances will ensure easy access for installation and
maintaining the unit during the products life

Place the wall mounting bracket onto the wall, ensuring the correct
orientation, and the bracket is level. Mark off 4 points on the wall where you
will be securing the bracket, the bracket has numerous holes and slots to
allow the bracket to be mounted at different points depending on the wall you
are mounting it to. It is advised to have the fixing points spaced out as far as
possible to allow a more ridged and secure installation.

Using a 7mm masonry bit, drill the 4 points you marked off earlier to a depth
of 40mm, insert the 4 Rawl plugs into the wall that are supplied with this unit.

Secure the wall mounting bracket to the wall using the 4 brass screws
supplied with the unit.

Ensure all fixings are tight and bracket is secured to the wall.

Screw 2 X M6 Bolts into the top fixings on the bracket, only screwing them in
a 2-3 turns. Lift the unit onto the bracket and hook the unit onto the bolts using
the keyhole slots in the rear of the unit do not tighten the bolts yet. Fit the 2
remaining bolts through bottom holes in the rear of unit and into the wall
mounting bracket and tighten all 4 bolts.

Check to make sure the unit is secure to the wall mounting bracket.

Replace cover and refit all fixings that have been removed.

ROUTINE MAINTENANCE

ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN

To ensure continued full efficiency of the dehumidifier, maintenance
procedures should be performed as follows:

S

DISCONNECTED BEFORE CARRYING OUT ROUTINE

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.

DO NOT STEAM CLEAN REFRIGERATION COILS

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 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.

I

F ANY OF THE PRECEDING PROBLEMS OCCUR, CONTACT THE EBAC

ERVICE CENTER PRIOR TO CONTINUED OPERATION OF THE UNIT TO

PREVENT PERMANENT DAMAGE.

REPAIRS

1. Should an electrical component fail, consult the Factory Service

Center to obtain the proper replacement part.

2. If refrigerant gas is lost from the machine, it will be necessary to use

a Refrigeration technician to correct the fault. Contact the Factory
Service Center prior to initiating this action.

Any competent refrigeration technician will be able to service the

equipment. The following procedure must be used:

a. The source of the leak must be determined and corrected.

b. The machine should be thoroughly evacuated before

recharging.

c. The unit must be recharged with refrigerant measured

accurately by weight.

d. For evacuation and recharging of the machine, use the crimped

and brazed charging stub attached to the side of the refrigerant
compressor.

The charging stub should be crimped and rebrazed after

servicing. N
any part of the circuit. Service valves may leak causing further
loss of refrigerant gas.

3. The refrigerant compressor fitted to the dehumidifier is a durable
unit that should give many years of service. Compressor failure can
result from the machine losing its refrigerant gas. The compressor
can be replaced by a competent refrigeration technician.

Failure of the compressor can be confirmed by the following

procedure:

a. Establish that power is present at the compressor terminals

using a voltmeter.

b. With the power disconnected, check the continuity of the internal

winding by using meter across the compressor terminals. An
open circuit indicates that the compressor should be replaced.

c. Check that the compressor is not grounded by establishing that

a circuit does not exist between the compressor terminals and
the shell of the compressor.

EVER

allow permanent service valves to be fitted to
