INTRODUCTION
Designed for a wide range of applications, the CD85 dehumidifier is a rugged,
industrial unit which utilizes an energy-efficient compressor and a compact
portable design to provide easy efficient drying.
The CD85 has a number of special features:
• Compact Size
• High efficiency rotary compressor
• Ebac’s “Hot Gas” defrost system
• Exterior epoxy powder-coated finish
• Provision for permanent drainage
• All galvanized interior
• Extra long power cord
• 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 CD85 dehumidifier is a rugged, 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.
The unit incorporates a welded and galvanized steel chassis and is finished in
an epoxy coating for resilience to damage caused by rough handling.

COVERS
The CD85 covers can be swapped to allow the airflow direction to be changed
to better suit the application the unit is to be used for. To change the covers,
first remove the 4 off retaining screws and washers from each cover, swap
cover positions and replace 4 off retaining screws and washers. If changing
the evaporator covers then the filter retaining mesh should always be placed
behind the Evaporator Grille Cover. This is held in place with 4off M3 hex
head bolts.
Evaporator Grille Cover and Evaporator Blanking Cover are interchangeable.
Condenser Grille Cover and Condenser Blanking Cover are interchangeable.
Evaporator and Condenser covers are not interchangeable.
The different combinations available are shown below.

OPERATION
The following procedures should be followed to test the CD85 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 15 Amp electrical outlet.
2. Check dehumidification process as follows:
A. Place unit on a level surface.
B. Start up unit by turning the humidistat control knob until the
unit turns on.
C. Check that the compressor is running.
D. Leave the machine running for 15 minutes.
E. Observe the evaporator coils through the evaporator filter panel
i. If the air temperature is below 80° F, an even coating of
frost should cover the entire evaporator coil
ii. If the air temperature is above 80°F, frost and/or droplets
of condensed water should cover the entire
evaporator coil.
F. After continuous running time of approximately 55 minutes, the
unit will enter “Hot Gas” defrost mode for 5 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.
TO ENSURE CONTINUED FULL EFFICIENCY OF THE
DEHUMIDIFEIR, MAINTENANCE PROCEDURES SHOULD BE
PERFORMED AS FOLLOWS:
CAUTION:
ONCE THE UNIT HAS BEEN SWITCHED OFF, WAIT AT
LEAST FIVE MINUTES BEFORE RESTARTING.

ROUTINE MAINTENANCE
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. 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 evaporator filter cover. The evaporator coil
should be evenly frost coated across its surface. At temperatures
above 80°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.
5 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 E BAC

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.
