WARNING: DO NOT USE OR STORE THE DEHUMIDIFIER NEAR A HEAT
SOURCE, AS THE UNIT CONTAINS PRESSURISED FLAMMABLE REFRIGERANT
GAS (R290-HYDROCARBON PROPANE)

R290 REFRIGERANT GAS (HYDROCARBON PROPANE)

H220: Extremely Flammable Gas.

H280: Contains Gas Under Pressure, May Explode if Heated.

R290 refrigerant gas complies with UK & European environmental
directives.

R290 has a low GWP (Global Warming Potential) of 3 and CO2
equivalent to 0.0006t

The dehumidifier contains approximately 200g of R290 refrigerant gas. The
refrigerant system MUST NOT be perforated or punctured.

• DO NOT use or store in an unventilated space with an area smaller than

4m² per unit. The room must be such as to prevent stagnation of possible
leaks of refrigerant gas as there could be a danger of fire or explosion
hazard should the refrigerant come into contact with electric heaters,

WATER TANK & CONTINUOUS DRAINING

This machine has a 7 litre internal water tank. When the water tank is full, the
machine will automatically shutdown at 5 litres and enter standby mode, on
the LED display the ‘Full Water Tank’ will light up and an alarm will sound.

TO EMPTY THE TANK

1. Open the water tank door at the
front of the machine.

2. Pull water tank out of the holding
clips and empty.

3. Replace the water tank back in
the holding clips and close the
door.

NOTE: The water tank full alarm will

continually sound when the tank is removed and will not turn off
until the tank is empty and correctly seated back in the machine.

PREPARATION FOR CONTINUOUS DRAINING

An external drainage pipe enables continuous dehumidifying without having
to empty the water tank.

1. Extract the water tank
from the machine
and remove the plug
from the water tank
spout.

2. Locate the external
drainage pipe and
feed it through the
drainage pipe outlet
hole on the side of the
machine.

3. Place the end of the pipe onto
the water tank spout and replace
the tank back in the machine.

4. Place the external end of the
pipe into a suitable receptacle/
drain ensuring that the end of the
pipe is below the level of the
outlet in the unit body.

NOTE: If using a receptacle, make

sure it is large enough as the
machine can produce up to 50 litres of water in a 24 hour period.

10

Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]

NOTE: The pipe has an internal diameter of 13mm and is 100cm long.

NOTE: DO NOT submerge the end of the pipe in water, as this may cause

water to be drawn back up into the machine.

TIMING AND ON/OFF FUNCTION

Setting the timer for both powering on and off will initiate the cycle timer

mode.

SETTING OF TIMER - POWER ON

1. When the machine is powered off, press the “Timing” button.

2. The “Timing On” icon will flicker and the time set will flicker on the display
screen.

3. Press the “+” or “-” buttons to adjust the timing. The dehumidifier will make
a sound once the button is pressed. The time set will increase or decrease
by “1”, holding the button for 2 seconds will continually increase or
decrease the time.

4. Once the required time is set, non-action of the buttons for 10 seconds the
dehumidifier will accept the new setting and the “Timing On” icon will
flicker (Ranging from 0 to 24 hours, and 0 hours as default).

SETTING OF TIMER - POWER OFF

1. When the machine is powered on, press the “Timing” button.

2. The “Timing Off” icon will flicker and the time set will flicker on the display
screen.

3. Press the “+” or “-” buttons to adjust the timing. The dehumidifier will make
a sound once the button is pressed. The time set will increase or decrease
by “1”, holding the button for 2 seconds will continually increase or
decrease the time.

4. Once the required time is set, non-action of the buttons for 10 seconds the
dehumidifier will accept the new setting and the “Timing Off” icon will
flicker (Ranging from 0 to 24 hours, and 0 hours as default).

HUMIDITY CONTROL

• When the rooms humidity value is 3% lower than the set humidity on the

machine, the compressor will shut down, the fan will delay shut down for
3 minutes and then shut down; and when it is 3% higher than the
humidity value set on the machine, both the fan and compressor will
start to operate.

• When the humidity is set at the minimum value (10%), the machines

default will enter the continuous dehumidifying mode.

11

Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]

• When started, the compressor will start 3 seconds later and when it is

shut down, the fan will run for 3 seconds.

• If a fault of the humidity sensor occurs, the machine will turn to the

continuous dehumidifying mode.

• If a fault of the coil sensor occurs, the machine will turn to the timing

defrosting mode (See Defrosting Mode).

PROTECTION FUNCTION

• Once shut down, the compressor will take 3 minutes to restart. Quick

start is available for the first power-on.

• Power off memory: For abrupt power outage or accidental unplugging,

the machine will automatically return to the operating state right before
the ‘incident’, and continue at that state for the next power-on.

MAINTENANCE

WARNING: ALWAYS UNPLUG THE DEHUMIDIFIER BEFORE PERFORMING
ANY CLEANING OR MAINTENANCE OPERATIONS.

CLEANING THE CABINET

• Use a soft damp cloth to clean the exterior.

• Never use harsh chemicals or abrasive cleaning agents as these may

damage the casing finish.

• Clean the water tank and its cover regularly to prevent mould build up.

CLEANING THE AIR FILTER

1. At the front of the machine, pull the filter
upwards, using the tab.

2. Wash the filter under running water to
remove any dust and dirt.

3. Allow the filter to dry naturally.

4. Refitting is the reverse process.

The frequency depends on the duration
and the level of dust in the environment. If
the machine is being used regularly, it is
recommended that you clean the filter
every 2 weeks.

STORAGE

• Unplug from the mains socket.

• Empty any water from the tank.

• Clean and reinstall the filter.

• Cover the dehumidifier to prevent dust getting into the workings.
