WARNING! READ THESE ELECTRICAL SAFETY INSTRUCTIONS
THOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE
MAINS SUPPLY.
Before switching the product on, make sure that the voltage of your electricity
supply is the same as that indicated on the rating plate. This product is
designed to operate on 230VAC 50Hz. Connecting it to any other power
source may cause damage.
This product may be fitted with a non-rewireable plug. If it is necessary to
change the fuse in the plug, the fuse cover must be refitted. If the fuse cover
becomes lost or damaged, the plug must not be used until a suitable
replacement is obtained.
If the plug has to be changed because it is not suitable for your socket, or due
to damage, it should be cut off and a replacement fitted, following the wiring
instructions shown below. The old plug must be disposed of safely, as insertion
we would emphasise the electrical hazard.
We strongly recommend that this machine is connected to the mains supply
via a Residual Current Device (RCD).
If in any doubt, consult a qualified electrician. DO NOT attempt any repairs
yourself.
WARNING: WIRES IN THE MAINS LEAD ARE COLOURED IN
ACCORDANCE WITH THE FOLLOWING CODE:
GREEN/YELLOW = EARTH, BLUE = NEUTRAL, BROWN = LIVE.
•The BLUE wire must be
connected to the
terminal marked N or
coloured black.
•The BROWN wire must
be connected to the
terminal marked L or
coloured red.
•The YELLOW AND
GREEN wire must be

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 0.00084t.
The dehumidifier contains approximately 280g 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,
stoves or other sources of ignition.
• Refrigerant gas may be odourless.
• DO NOT use the product and contact the retailer for advice if damage
has occurred to the unit which may have compromised the refrigerant
system.
• Any repairs or maintenance must only be carried out on the unit by a
suitably qualified engineer. Before opening and servicing the unit, the
authorized engineer must be in possession of a copy of the
manufacturer's service manual and must follow the safety information
contained within it to ensure all hazards are minimized.

ASSEMBLY
• Align the fixing holes of the tubular
handle with the holes on the rear
of the dehumidifier.
• Fix the handle to the dehumidifier
using the 4 fixing screws supplied,
as shown.
WHEELS
1. Incline the machine body, as shown, and fix the axle on the bottom of the
machine body using the 4 screws.
2. Using the nuts and washers, fix the wheels to the axle rod.
3. Once the wheels have been installed, place the machine in the upright
position.
NOTE: Once assembly is complete, leave the machine to stand for a
minimum of 1 hour, this is for the refrigeration gases to settle
before use.

CONTINUOUS DRAINING
This dehumidifier does not contain an internal water tank. An external prefitted
drainage pipe enables continuous dehumidifying without having to empty a
water tank.

Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]
Page 9
PREPARATION FOR CONTINUOUS DRAINING:
1. Locate the prefitted external
drainage pipe on the side of the
machine.
2. Place 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
70 litres of water in a 24 hour period.
NOTE: The pipe has a diameter of 16mm and is 90cm 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
When the machine is powered on, you can set the timer to power off; and
when the machine is powered off, you can set the timer to power on. 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.
• 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.
CLEANING THE AIR FILTER
1. At the front of the machine, pull
the filter out sideways, 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.
• Clean and reinstall the filter.
• Cover the dehumidifier to prevent dust getting into the workings.
