DEHUMIDIFIER PRINCIPLE
Dehumidifiers remove moisture from the air that is circulating through the
appliance.
The resulting reduction of relative humidity helps prevent rust, rot, mould,
mildew and condensation within the room, or other enclosed spaces where
the dehumidifier is used.
A dehumidifier consists of a motor-compressor unit, a refrigerant condenser,
an air circulating fan, a refrigerated surface, a means of collecting and
disposing the condensed moisture and a cabinet to house these components.
The fan draws air through the refrigerated surface and cools it below its dew
point, removing moisture which is collected and led away. The cool air then
passes the hot condenser, where it is reheated. With the addition of other
radiated heat, the air is discharged into the room at a higher temperature but
lower relative humidity than when the air entered the appliance. Continuous
circulation of the room air through the appliance gradually reduces the relative
humidity in the room.
The appliance 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 guarantees positive de-icing, thereby
optimizing operation at low temperatures. Should the ambient temperature fall
below 15°C then ice will form on the evaporator coil as the air is passed over
it, and in turn the efficiency of the unit will drop. To prevent the buildup of this
ice on the evaporator coil an electronic timer is incorporated to energize the
hot-gas defrost valve. Operating the hot-gas valve causes the evaporator coil
to defrost and the water to drain down to the condensate well and then is
pumped out of the unit.
The appliance has been designed to work in ambient temperatures between
3°C and +35°C. Should the temperature in the room become excessive a
thermostat within the compressor casing will open and dehumidifying will stop,
until the thermostat resets itself.
UNPACKING
Carefully remove the appliance from its transit box and visually check for
signs of transit damage. If there is evidence of damage DO NOT attempt to
operate the appliance, call your supplier for advice. Do not discard the
packing; it will be useful when transporting the dehumidifier unit in the future.

INSTALLATION
POSITIONING:
Position the appliance 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.
NOTE: Both inlet grille and outlet grille of the appliance must have clear space
around them and not be obstructed in anyway. The unit must also be on a
level surface.
Appliance shall be installed, operated and stored in a room with a floor area
larger than 4M
2
.
WIRING:
Connect the power mains cable to a 13 Amp power supply as follows: -
230V supply
Brown Live
Blue Neutral
Green/Yellow Earth (ground)
DRAINAGE:
The appliance is fitted with a condensate pump which collects all the
condensate. As the condensate pump fills with water it will automatically
activate and empty via the tube outlet located at the back of the dehumidifier,
this should be connected to a water container or permanent drain. If the pump
fails, then the dehumidifier will automatically switch off. NOTE: after the pump
has emptied there will still be a small amount of water standing in the pump
reservoir which will leak if the dehumidifier is not kept upright.

ROUTINE SERVICE
WARNING:
ENSURE THE POWER CORD TO THE APPLIANCE IS DISCONNECTED
BEFORE CARRYING OUT ROUTINE SERVICE. SERVICING AND REPAIR
SHOULD ONLY BE CARRIED OUT BY A SUITABLY QUALIFIED PERSON.
To ensure continued full efficiency of the appliance, 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 THE REFRIGERATION COILS
2. Check that the fan is firmly secured to the motor shaft and that the fan
rotates freely. The motor is sealed for life and does not require any
lubrication
3. To check the refrigerant charge, run the appliance for 15 minutes. The
evaporator coil should be evenly frost coated across its surface. At
temperatures above 25°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.
