INTRODUCTION

Designed for a wide range of applications, the CD35 is a rugged, compact unit
which incorporates its own tank for collected moisture with an automatic
shutoff once the tank is fully. Offices, shops, houses, restaurants and
storerooms can be protected by this simple answer to humidity control.

The CD35 has a number of special features:

•

Adjustable humidistat

•

“Hot Gas” defrost system with solid state controller

•

Whisper-quiet fan

•

Water tank with “full” indicator lamp

•

All galvanized interior

•

Exterior epoxy powder-coated finish

•

Four independent heavy-duty castors

•

Fully enclosed coils

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 CD35 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.

The CD35 dehumidifier is fitted with an adjustable humidistat to enable you to
select the level of dryness that you desire.

FEATURES

The Adjustable Humidistat: The adjustable humidistat enables you to

maintain the required level of dryness within a room. The humidistat switches
off the CD35 when the relative humidity falls to the level predetermined by the
position of the humidistat control.

The Water Tank: When the water tank has reached its capacity, a float
mechanism will activate a microswitch lever and switch off the machine. The
container-full indicator will also illuminate.

Before emptying the water container, disconnect the power supply and allow
the dryer to stand for five minutes. Remove the container from the rear of the
unit and when emptied, replace, taking care to ensure that the float
mechanism is correctly positioned. Restart unit as instructed in the following
Operation section of this manual.

UNPACKING & INSTALLATION

After removing the CD35 from its shipping container, visually check for signs
of damage. If there is evidence of damage, do not operate. Call your supplier
for advice. Do not discard the packing as it will be useful when transporting
the machine in the future.

Wiring: Connect the power cord to a grounded single phase, 15 Amp fused,
standard household wall socket.

POSITIONING

Single Room: Position the CD35 in the center of the room to be dried.

However, if a damp patch is particularly apparent, the outlet grille should be
directed towards it. If the CD35 cannot be positioned centrally, a minimum
space of 6” should be allowed around the dryer.

Several Rooms: To dry a number of rooms simultaneously with the most
efficiency, the dryer as to be positioned between the rooms. Ensure that all
doors are left ajar allowing a patch for the air to circulate to the unit. An
auxiliary circulation fan would be helpful.

SPECIAL FEATURES (where fitted)

CONDENSATE PUMP:

The CD-35 dehumidifier unit can be fitted, either in the factory, or as retro-fit,
with a condensate pump. This condensate pump will allow the unit to run
unattended, with the condensate run off to a permanent drain and can be
used up to 150 feet (50 meters), below the level of a permanent condensate
drainage point.

HUMIDISTAT CONTROL:

The CD-35 dehumidifier unit is fitted with a control humidistat which measures
the relative humidity of the air within the room. The humidistat incorporates a
pointer and scale, which can be adjusted, and set to a relative humidity level
that is acceptable to maintain the required conditions within the room. The
humidistat controls the on/off function of the dehumidifier. When the relative
humidity of the air in the room falls below the set point of the humidistat the
dehumidifier will switch off, but when the relative humidity of the air starts to
rise again and passes the set point the unit will switch on. The humidistat is
used for the on/off function as it is a cost effective method which ensures
power is only used when needed.

TEMPERATURE CONTROLLED DEVICE:

The CD-35 dehumidifier unit is fitted with a temperature sensitive device
which operates in conjunction with the defrost control. In normal operation the
defrost control will come into operation every 45 minutes. This is to ensure
that there will be no build up of ice at lower temperatures. At very low
temperatures it is still possible for the defrost device not to clear the ice
completely from the evaporator coil. To ensure that even at these very low
temperatures all the ice is cleared from the coil, the temperature control
device will stop the fan (preventing air movement). This will increase the
temperature of the evaporator coil even higher, causing all the ice to melt from
the coil during the defrost mode. Where year round conditions need to be
maintained, the dehumidifier unit will have to operate across a wider range of
temperatures. To ensure that the dehumidifier unit operates at its most
efficient, the temperature control device will restrict the defrost operation to
the times when the ambient temperature falls below 25°C.

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 three 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

To ensure continued full efficiency of the dehumidifier, maintenance
procedures should be performed as follows:

Removal of the cover is achieved by means of four screws at the sides of the
unit at base level. With the cover removed all maintenance can be carried out.

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”/150 mm) 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. Using mobile DD heavy medium oil, lubricate the
motor bearing with 10 drops every 6 months.

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 20°C, 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.
