agent or similarly qualied person in order to

avoid hazard.

• If the appliance 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.

• Due to the high pressures within the refrig-

eration 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 appliance is switched off at the mains

power supply for any reason, it must be

allowed to stand at rest for at least three

minutes before restarting. Failure to do so

may cause the appliance to blow the fuses

owing to the compressor due to there being a

refrigerant imbalance.

• The Global Warming Potential (GWP) of

refrigerants used in products manufactured

should only be done so by El-Bjorn UK Ltd

or its service agent.

DEHUMIDIFIER PRINCIPLE

Dehumidiers 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 dehumidier is used.

A dehumidier 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 efciency 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 pan and into the drainage tube.

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.

EN

UNPACKING

Carefully remove the appliance from its transit packaging 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 dehumidier 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 oor area larger than 4M2.

WIRING:

The unit will come fully wired to the relevant plug

NOTE: When a generator is used to supply the power, it is essential to check the minimum kva required

in the technical section within this manual. The generator must be started before connection is made to

the dehumidier.

DRAINAGE:

The appliance is tted with a condensate pump which collects all the condensate. As the condensate

pump lls with water, it will automatically activate and empty via the tube outlet located at the back of

the dehumidier, this should be connected to a water container or permanent drain. If the pump fails,

then the dehumidier 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 dehumidier is not kept upright

EN

OPERATION

• Once the appliance is installed turn the power supply on, then turn the on / off switch to the ‘I’

position, note the display will ash for approximately 1 second then show the humidity set point

for approximately 12 seconds. Also all the indicator lights will illuminate for the same duration.

After this brief period the display will show the room humidity and all the lights will go off. The

machine is now powered up (POWER light illuminated) and ready to operate. Then carry out the

following: -

• Set the humidity set point to lowest setting (35% RH) as follows.

o Press the UP and DOWN arrow keys together for 3 seconds and the display will start to

ash

o Use the UP and DOWN arrow keys to adjust the set point to 35%

o Press the RIGHT arrow key to save (if the RIGHT arrow key is not pressed for 3 seconds

the selection is cancelled)

o Once set to 35% and saved the compressor will start and the drying light will illuminate

• Check that the compressor is running

• Leave the appliance to run for approximately 15 minutes

• Observe the coils through the lter grille to conrm frost formation or weeping of the evaporator

coil

o If the air temperature is below 25°C, an even coating of frost should cover the entire

evaporator coil.

o If the air temperature is above 25°C, frost and/or droplets of condensed water should

cover the entire evaporator coil.

When the unit is operated in an ambient of less than 15°C, a defrost cycle should occur. This will be at

intervals of no more than every hour and will last no more than 5 minutes. The exact time is impossible

to predict as the unit is tted with a temperature sensitive defrost control. When in defrost the

DRYING lamp will extinguish and the DEFROST light illuminate. After defrost the lights will switch

back.

After using the appliance, turn it off for 5 minutes to allow the condensate on the coils to drain into the

pump reservoir. Then turn the appliance back on and press the momentary purge switch for 20 to 30

seconds to evacuate the water from the pump reservoir.

LIGHT FUNCTIONS:

The unit has four LED indicators, located on the top of the unit. The following lists the functions of

these lights:

1 - ON / OFF

Green solid – Indicates power ON

2 – DRYING

Blue ashing – Indicates drying selected (compressor has not started)

Blue solid – Indicates drying ON (compressor has started)

3 – DEFROST

Yellow ashing (Approximately every 5 seconds) – Defrost cycle active

Yellow solid – Defrost in progress

4 – ALARM

Yellow Flashing followed by Red solid – Pump Fault

If, after carrying out the above procedures, the appliance does not appear to function properly,

refer to the Trouble Shooting section, which follows, or contact your supplier.

ROUTINE MAINTENANCE

WARNING:

ENSURE THE POWER CORD TO THE APPLIANCE IS DISCONNECTED BEFORE

CARRYING OUT ROUTINE MAINTENANCE.

ANY SERVICING OR REPAIR SHOULD ONLY BE CARRIED OUT BY EL BJORN

UK LTD OR ITS SERVICE AGENT.

To ensure continued full efciency 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 ns

with compressed air. Hold the nozzle of the air hose away from the coil (approx 6”) to avoid

damaging the ns. Alternatively, vacuum clean the coils.

WARNING:

DO NOT STEAM CLEAN THE REFRIGERATION COILS

2. 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.
