INTRODUCTION

Designed for a wide range of applications, the CS90H dehumidifier is a
rugged, industrial unit which utilizes an energy-efficient compressor and a
compact portable design to provide easy efficient drying.

The CS90H 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

•

Digital humidistat 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.

A digital Humidistat is included which allows for precise humidity control. A
programmable display lets you set a specific desired humidity level.

The CS90H 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 CS90H for correct
operation:

1. After unpacking, examine all external features to confirm damage­free shipment. Report all defects and damage at once. Connect the
power cable to a grounded 15 Amp electrical outlet.

2. Setting the Digital Humidistat

The Digital Humidistat is factory preset to give the optimum
level of control. Only adjustment of the desired set point is
required.

During normal operation, the display shows the current % Relative
Humidity within the space being conditioned.

The required humidity level can be set as follows:

• Press the “S” button once to access the set point

• Press the ▲ or ▼ button to change the display to the

desired Humidity level

• Press the “S” button again to save the set point – The
control returns to displaying the current % Relative
Humidity

3. Check dehumidification process as follows:

TO ENSURE CONTINUED FULL EFFICIENCY OF THE

DEHUMIDIFEIR, MAINTENANCE PROCEDURES SHOULD BE

PERFORMED 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.

CAUTION:

Date : - 02/12/15

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.

When the unit is defrosting, the % Relative Humidity displayed on the
digital controller may increase as a result of the ice / frost melting. This
is quite normal and the display will return to its normal reading when the
unit returns to dehumidifying mode. (Fan running)

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.

ONCE THE UNIT HAS BEEN SWITCHED OFF, WAIT AT

LEAST FIVE MINUTES BEFORE RESTARTING.

ROUTINE MAINTENANCE

ENSURE THAT THE POWER CORD TO THE MACHINE HAS BEEN

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

2. Check that the fan rotates freely. The fan motor is sealed for life

3. To check the refrigerant charge, run the unit for 15 minutes and

4. Check all wiring connections.

5 In order to check the defrost operation, the unit needs to be

nozzle of the air hose away from the coil to avoid damaging the fins.
Alternatively, vacuum clean the coils.

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

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

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
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.
