UNPACKING
Carefully remove the PD120 dehumidifier unit from its transit box and visually check for signs
of transit damage. If there is evidence of damage DO NOT attempt to operate the unit, call your
supplier for advice. Do not discard the packing, it will be useful when transporting the
dehumidifier unit in the future.
INTRODUCTION
The Ebac PD120 industrial dehumidifier removes moisture from the air through the refrigeration
process.
The Ebac PD120 is basically comprised of:
1) A compressor
2) A refrigerant evaporator coil
3) A refrigerant condenser coil
4) One circulation fan
5) A remote humidistat
6) A cabinet to house the above components
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 with which it entered.
Continuous circulation of air through the dehumidifier gradually reduces the relative humidity
within the area.
The PD120 dehumidifier is a rugged, reliable drying unit designed to operate effectively over a
broad range of temperature and humidity conditions.
The PD120 dehumidifier uses a remotely mounted adjustable humidistat to enable you to select
the level of dryness.

INSTALLATION
POSITIONING:
Position the dehumidifier unit in the center of the room to be conditioned if at all possible.
However if a damp patch is particularly apparent the outlet grille should be pointed towards it if
possible.
This unit can also be used in a duct system where applicable, please see the diagrams on the
following pages which identify the overall sizes of the unit and also the mounting points.
NOTE: Both inlet grille and outlet grille of the dehumidifier unit must have clear space around
them and not be obstructed in anyway.
Before connecting this unit to the relevant power supply the following must be carried out.
Selecting the correct fan speed – The PD120 has a low fan speed and a high fan speed and the
required speed must be chosen before installation. To select the correct fan speed firstly remove
the air inlet cover via the 10off M4 hex head bolts, then remove the electrical box cover via the
4off M4 hex head bolts. Once the electrical box cover is removed the supplied link wire must be
wired between either the ‘C’ and ‘L’ or the ‘C’ and ‘H’ terminals on the terminal block. This is
shown below.
Before the unit will switch on it must have a low voltage humidistat wired into it with the NC
contacts wired to the terminal block inside the electrical box as shown below.

OPERATION
The following procedures should be followed to test the PD120 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 power source.
2) Install drain tubing as required.
Caution: Do not operate the machine without the covers for any longer than necessary. Do
not remove/ replace the covers when the unit is in operation.
Check dehumidification process as follows:
A. Place unit on a level surface.
B. Start up unit as follows:
i.Ensure fan speed selection has been chosen as mentioned in previous pages and also
that the humidistat has been wired in.
ii.Rotate humidistat control knob to fully counter clockwise, minimum setting.
iii.Plug unit into power supply and rotate humidistat knob clockwise to desired setting.
C. Check that the compressor is running.
D. Leave the machine running for 15 minutes.
E. Observe the evaporator coils behind the filter on the air inlet end of the unit to confirm
frost formation.
i.If the air temperature is below 70ºF, an even coating of frost should cover the entire
evaporator coil, except for the last one or two coils.
ii.If the air temperature is about 70ºF, frost and/or droplets of condensed water should
cover the entire evaporator coil.
F. As the drain tray fills, the condensate will automatically drain by gravity.
If after carrying out the above procedures, the unit does not appear to function properly, refer to
the Trouble Shooting section or contact the Factory Service Center.
WARNING:
• Due to the high pressures within the refrigeration circuit, under no circumstances must direct
heat be applied to the evaporator coil in an attempt to remove the build up of ice.
• No attempt should be made to cut open any part of the refrigeration circuit due to high
pressures and gas involved. If the unit is switched off at the mains power supply for any
reason, the unit must be allowed to stand at rest for at least five minutes before restarting.
Failure to do so may cause the unit to blow the fuses owing to the compressor due to there
being a refrigerant imbalance.
ROUTINE MAINTENANCE
PD120
OWNERS MANUAL
Date :-
10/12/13
Drawing No. :- TPC325
Issue :- 8
WARNING: ENSURE THAT THE POWER CORD TO THE MACHINE
HAS BEEN DISCONNECTED BEFORE CARRYING OUT
ROUTINE MAINTENANCE ON ITEMS 1, 2, 4, 5, AND 6.
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 (approx 6”) to avoid damaging the fins. Alternatively, vacuum clean the coils.
WARNING: DO NOT STEAM CLEAN REFRIGERATION COILS.
2. 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.
3. To check the refrigerant charge, run the unit for 15 minutes and briefly remove the
cover. The evaporator coil should be evenly frost coated across its surface. At
temperatures above 70°F, 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.
4. Check all wiring connections.
I
F ANY OF THE PRECEDING PROBLEMS OCCUR, CONTACT THE EBAC SERVICE 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
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.
