UNPACKING
Carefully remove the PD220 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 PD220 industrial dehumidifier removes moisture from the air through the
refrigeration process.
The Ebac PD220 is basically comprised of:
1) A compressor
2) A refrigerant evaporator coil
3) A refrigerant condenser coil
4) One circulation fan
5) A 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 dehumidifier is a rugged, reliable drying unit designed to operate effectively over a broad
range of temperature and humidity conditions.
The dehumidifier uses an internally mounted adjustable humidistat to enable you to select the
level of dryness.
The unit can also be used with an external humidistat or the EIPL touch display panel (via the 6
pin connector) to control 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.
Connect the drainage outlet to a suitably sized hose and run the hose to a permanent drain.
Connect the unit power cable to a grounded power source.
NOTE:
Both inlet grille and outlet grille of the dehumidifier unit must have clear space around them
and not be obstructed in anyway. For correct installation and operation, the unit inlet and
outlet must have a clearance of 0.5M from all adjacent surfaces and or structures.
Optional Control Methods
1. External Humidistat
• Connections for an external humidistat are available on the 6 pin connector above the
main isolator.
• The remote humidistat should have a normally open set of contacts which close on
humidity rise.
• This connection is low voltage low current, suggested cable specification 2 core 16/0.2
(0.5mm) screened cable.
• Connection is across pins 5 and 6 of the 6 pin connector
• The Jumper on the main control board should be removed from position “E” to allow
this feature to operate.

4 Time To Start Displays the time to start drying (mins) or “on” if already drying
5 Time To Defrost
If defrost mode is selected, this option shows the remaining time
until defrost will occur. The yellow defrost light will be flashing
indicating a defrost is required.
6 Time In Defrost
If defrost is currently occurring, the yellow defrost light will be
solid, and the display will show the time remaining before
defrost ends.
Defrost not required or active the display will show “—“
Notes on Time values above
2 digits no decimal point indicates a time > 10mins
2 digits with a decimal point indicates mins and tenths of a min, ie 8.5 = 8mins 30 secs

Menu Display Information
1 Humidity Indicates the current room Humidity.
Operation
Plug the unit into a suitable wall socket and power on.
Set the Yellow/Red isolator switch to ON.
Note the Power On Indicator shows Solid Green.
To prevent the compressor starting too quickly after being powered down, there is an inbuilt
compressor off timer. This delayed start prevents the compressor for restarting for 6 minutes after
being switched off. Note this feature is reset when the isolator is set to OFF or power is removed from
the unit.
The dehumidifier remembers the last mode of operation, and also the previously adjusted set point.

Once the dehumidifier is started, the drying / recirculation light will indicate the selected mode or
operation.
Adjust the mode, as required. (Recirculation or Drying).
In drying mode, the display will show the room humidity level.
In recirculation mode the display shows the current room temperature.
Using the Menu Key cycle through the menu options to the Set RH page, using the up/down and enter
keys adjust the humidity to the desired level.
The dehumidifier will now self-regulate to maintain the desired humidity level. The unit will
automatically defrost as needed. In warmer climates defrost is not required, allowing the dehumidifier
to continually dry.
If, after carrying out the above procedures, the appliance does not appear to
function properly, refer to the Trouble Shooting section, which follows, or contact
EIPL.

ROUTINE SERVICE
WARNING: ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN
DISCONNECTED BEFORE CARRYING OUT ROUTINE SERVICE. THE
SERVICING AND REPAIR OF THIS UNIT SHOULD ONLY BE CARRIED
OUT BY A SUITABLY QUALIFIED PERSON.
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.

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
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.
