INTRODUCTION
Designed for a wide range of applications, the CS90E dehumidifier is a
rugged, industrial unit which utilizes an energy-efficient compressor and a
compact portable design to provide easy efficient drying.
The CS90E 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
•Extra long power cord
•Integral condensate pump
•Electronic humidity controller
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 CS90E controls consist of an electronic humidity controller, incorporating
Bluetooth connectivity and Real Time Clock, allowing the unit to interface with
Android and IOS smart phones and provide additional control and data
logging features. The respective apps are available for free download through
the normal channels
Smartphone App
The Smartphone interface allows the following additional functions
a) Real time monitoring of the relay status and room conditions
b) Adjustment of Control set point (To allow this functionality, the link fitted to
J3 on the main controller board, will need removing)
c) Data logging of, Time, Temperature, Humidity, Relay Status, Control and
Alarm Set points
d) Adjusting the data Logging Interval
e) Resetting the data log
f) Downloading logged data
g) Emailing logged data in RAW or CSV formats (Allowing importing into
Excel)

The CS90E 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.

OPERATION
The following procedures should be followed to test the CS90E 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. Setting the humidistat
•Turn fully clockwise
3. Check dehumidification process as follows:
A. Place unit on a level surface.
B. Start up unit by turning the ON/OFF switch to ON
C. Check that the compressor is running.
D. Leave the machine running for 15 minutes.
E. Observe the evaporator coils through the rear upper grill, to
confirm frost operation.
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 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 top 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 In order to check the defrost operation, the unit needs to be
operated in an ambient temperature of less than 15°C for at least 1
hour. When operated In this condition the unit should defrost at
least once every hour. The defrost mode can be monitored by
observing the ice melting on the coil face, prior to defrost the face
will show a white coating of frost, which should clear during defrost
IF ANY OF THE PRECEDING PROBLEMS OCCUR,CONTACT THE EBAC
SERVICE CENTER PRIOR TO CONTINUED OPERATION OF THE UNIT TO
PREVENT PERMANENT DAMAGE.
WARNING:
ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN
DISCONNECTED BEFORE CARRYING OUT ROUTINE
MAINTNENANCE
WARNING:
DO NOT STEAM CLEAN REFRIGERATION COILS

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. NEVER 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.
