INTRODUCTION
Designed for a wide range of applications, the WM150 is a rugged, industrial unit,
which utilizes an energy-efficient compressor and a compact portable design to
provide easy efficient drying.
The WM150 has a number of special features:
• High efficiency rotary compressor
• Ebac’s “Reverse Cycle” 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 WM150 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 WM150 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. Turn the power supply on, then turn the on / off switch to the ‘I’ position, note
the display will flash for approximately 1 second then show the humidity set
point for approximately 12 seconds. Also all the indicator lights will illuminate
for the same duration. After this brief period the display will show the room
humidity and all the lights will go off. The machine is now powered up (POWER
light illuminated) and ready to operate. Then carry out the following: -
c. Set the humidity set point to lowest setting (35% RH) as follows.
i. Press the UP and DOWN arrow keys together for 3 seconds and the display
will start to flash
ii. Use the UP and DOWN arrow keys to adjust the set point to 35%
iii. Press the RIGHT arrow key to save (if the RIGHT arrow key is not pressed
for 3 seconds the selection is cancelled)
iv. Once set to 35% and saved the compressor will start and the drying light
will illuminate
d. Check that the compressor is running.
e. Leave the machine running for 15 minutes.
f. Observe the evaporator coils through the rear upper grille, to confirm frost
formation.
g. If the air temperature is below 25ºC, an even coating of frost should cover the
entire evaporator coil.
h. If the air temperature is above 25°C, frost and/or droplets of condensed water
should cover the entire evaporator coil.
i. When the unit is operated in an ambient of less than 15°C, a defrost cycle
should occur. This will be at intervals of no more than every hour and will last
no more than 5 minutes. The exact time is impossible to predict as the unit is
fitted with a temperature sensitive defrost control. When in defrost the
DRYING lamp will extinguish and the DEFROST light illuminate. After defrost
the lights will switch back
3. After using the WM150, turn it off for 5 minutes to allow the condensate on the coils to
drain into the pump reservoir.
CAUTION
DO NOT REMOVE COVERS WHEN THE UNIT IS IN OPERATION
CAUTION
ONCE THE UNIT HAS BEEN SWITCHED OFF, WAIT AT LEAST
5 MINUTES BEFORE RESTARTING

INSTALATION
The WM150 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 WM150 Dehumidifier
1 X Mounting Bracket
4 X Rawl plugs and screws
4 X M6 Hex Head Bolts, flat and spring washers
For mounting the WM150 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 (i.e. walls ceilings 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 SERVICE
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.
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.
I F ANY OF THE PRECEDING PROBLEMS OCCUR , CONTACT THE EIP S ERVICE C ENTER PRIOR
TO CONTINUED OPERATION OF THE UNIT TO PREVENT PERMANENT DAMAGE .

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 EVER allow permanent service valves to be fitted to 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.
