01

Do not cover or restrict the airflow from the outlet or inlet grills.
For maximum performance the minimum distance from a wall should be 20 cm and it
should be kept 50 cm from objects within the room.
Keep the filters or grills of the unit clean. Under normal conditions, filters or grills should
only need cleanig once every three weeks (approximately). Do not use the unit without
the mesh air filter as this will allow dirt to gather inside the dehumidifier and could
invalidate the warranty. A dirty filter will restrict the air flow into the machine which
will increase the resistance on the fan and could result in damage and might invalidate
the warranty.
Since the filters remove airborne particles, more frequent cleaning maybe
necessary depending on the air quality. Vacuum and wash the mesh filters with hot
soapy water and dry them before placing them back in the unit.
Quick visual safety guide on where or when not to use your dehumidier
Do not dry laundry directly above the unit. To prevent water entering the dehumidifier,
laundry should be placed at least 40 cm away from your dehumidifier.
Do not place the unit next to heat sources( e.g. electrical fires, fireplaces, etc.)
Desiccant dehumidifiers tend to absorb odours from the surrounding environment like
cigarettes, cooking, cosmetics, new furniture etc. This smell described as a burning
or sour smell. This released during operation as the zeolite disc is heated during
operation. This is not sign of a fault and the smell will fade with the time.
Do not store or use gasoline, petrol, paint, solvents or other flammable vapours
and liquids in the vicinity of this dehumidifier or any other appliance. Do not use
dehumidifiers where flammable gases or VOC can be released or accumulate.

QUICK REFERENCE GUIDE Air purifier Mode – No moisture will be extracted in this mode, which when used with filters
will purify the air. The UV and ionizer can also be used in this mode to further improve
the quality of air processed.
Please note :
1,when heater / dehumidifier / smart mode ison,due tothe large room space or
some other reasons,the target setting can not be reached even if the unit keeps on
working for a long time.If the unit works continuously more than 8 hours,the unit will
be shut off automatically
2,when heater / dehumidifier / auto mode is on,when the room temperature or humidity
reaches the target,the heating element will be closed,and fan keeps on working for 5
minutes,fan motor,fan louver will all closed,display is still on,and then,after 30 minutes,fan
motor and fan louver start to work again to detect the room temperature and humidity
(a),if it is necessary to turn on (room temperature is less then 1C or room temperature is 2%
above the settings),the heating element will be turned on to start the heating or dehumidify
(b),if it is not necessary to turn on,the fan will continue to work 5 miniutes and then closed,fan
louver is closed as well,display is still on.
And then repeated as per the above logic
3) when heating / dehumidifier / smart mode is on,when the heating element is on,if power
off manually,the heating element will be shut off immediately,the fan motor will keep
on working for 5 minutes ,in order to radiate the inner heat,please do not remove the plug
within 5 miniutes,in order to avoid destroying the unit.Fan motor and fan louver will stop
after 5 minutes

REMOTE CONTROL
laundry function: for the dehumidifier to operate continuously with maximum water
extraction until the tank is full, set the unit to High Fan mode and set the desired
humidity level to 35%-50% RH. 35% is very dry and the unit will work until water
tank is full as 35%RH is hardly achievable in The domestic environment. The louvres
should be set to either swing mode or to 45 degrees directing the airflow onto clothes /
laundry. Do not place clothes directly over the dehumidifier vents. Make sure that there
are no obstructions to either the hot air exhaust air flow, or the air inlet. For best
results place the laundry within 1.5 meters of the dehumidifier.
Please Note: If a permanent drainage pipe is fitted, the unit will not stop operation.
Setting the desired humidity to around 35% is good for a drying boost, on the units initial
run, or in emergencies. It is not recommended to use it with these settings for normal
operation in domestic/ office environment over a long period of time, as the air may become
uncomfortably dry.
For allowing more moisture in the air, press the humidity button to set to a higher percentage
value (e.g. 60-70%).
Humidity set to 50-55% RH - Recommended setting, great for domestic operation and dry
storage.
Humidity set to 60% RH - Great for personal comfort and applications where 50% RH is
considered too dry.
Humidity set to 70% RH - Ideal for unoccupied properties or where an
economical run is needed without the need to go drier than 70% RH
Red color means high humidity, RH>80%
Green color means comfortable, 80%≥RH≥60%
Blue color means dry, RH<60%

Lightweight Portable Design on castors
The dehumidier is built to be compact and lightweight. The castors on the bottom of the
unit make it easy to move from room to room. Your dehumidier is an advanced micro-CPU
controlled device capable of self-diagnostics. The LCD display may also show the error and
protection codes.
Other features and Indicators POSITIONING THE DEHUMIDIFIER
A badly positioned dehumidier will have little effect. In positioning the dehumidier please
ensure circulation of the air in not restricted around
the unit. At least 20 cm space should be allowed
around the unit.
This dehumidier is designed for indoor residential
/ small ofce applications only and any commercial
or industrial use will invalidate the warranty.
Use the dehumidifier in an enclosed area for
maximum efficiency. Close all external doors
and windows to create an effective operating
environment. Do not use outdoors.
Your dehumidier will begin to protect your space
from the harmful effects of excessive moisture as
soon as it is turned on. Excess moisture is dispersed throughout your home. For this reason,
the dehumidier should be positioned in a central and clear location so that it can draw this
moist air towards it from all over the home. A warm hallway or landing is an ideal position for
your dehumidier. If possible, leave interior doors ajar to allow air circulation between rooms.
Alternatively, if you have a serious problem in one area you can begin by positioning the
dehumidifier in that area and moving it to a more central location at a later date. Please
note the unit should not be placed directly against a radiator or other heat source. When
positioning your dehumidier, ensure that it is placed clear of any obstacle that may limit the
air movement, and it should be placed on a dry at surface.
Please Note: Do not force castors to move over carpet or uneven surfaces, nor move the unit
with water in the tank as it may tip over and spill.
WATER DRAINAGE
When the water tank is full, the unit will stop running. When this happens the TANK FULL
red light will show on the control panel.
Note: Only empty the water tank when it is full or before moving or storing the unit.
There are two ways to dispense collected water.
Use the internal water tank.
When the tank is full, the unit will smart stop running, and the Full
indicator light will ash. Grip the tank by its handle securely, and
carefully pull out. Empty the water tank and reinsert it into the
dehumidier. The tank must be in place and securely seated for
the dehumidifier to operate again. The dehumidifier will re-start
when the tank is restored to its correct position.
14 15

Do not remove the water tank immediately after the unit stops. Please wait a while to
avoid the water dripping into the unit and causing damage.
Only empty the water tank when it is full or before moving or storing the unit.
Do not rest the tank on the oor because the bottom of the tank could be uneven and
tank may fall and cause the water to spill.
When you remove the tank, do not touch sensors or any parts which are situated
behind tank. Doing so may damage the product. Be sure to push the tank gently all the
way into the unit. Banging the bucket against anything or failing to push it securely into
place may cause the unit not to operate.
Do not remove or damage the oat switch in the water-tank, otherwise the machine will
stop working.
Please make sure the water tank cover is put back into place correctly before the water
tank is reinserted.
If the water-tank is inserted incorrectly, the tank full indicator will flash. Remove the
water tank and reinsert to turn the indicator off and resume normal use.
At all times, avoid water entering the unit. It may cause an electrical hazard and
damage the unit.
NOTES:
This dehumidier has a continuous drain hole that can be connected to a plastic pipe with a
15 mm inner diameter (Not Supplied). Water can be smart plumbed in or drained into a sink,
a larger receptacle or through the wall into an outside drain. Please follow the steps below to
set your unit up for continuous drainage.
Set up continuous drainage (Select conguration)
Cut off the cover for the continuous drain on the back of the unit.
Pull out the water tank and connect a water tube of inner diameter 15mm to the drain
connector, and ensure the connection is tight * Please note, the water tube is not
supplied with the unit.
Return the water tank back into position within the unit.
1.
2.
3.
This unit uses gravity fall to dispose water hence the drain should be lower than the
dehumidier water outlet. Be sure to run the water pipe downward and let the water ow out
smoothly. Do not kink or bend the pipe.
NOTE: When the continuous drain feature is not being used, reverse the pipe installation, to
start the water collecting in the water tank.
The permanent drain can be used in conjunction with a water pump (e.g. when draining from
a cellar) to lift the water upwards.
Always shut off the unit and unplug it from the mains before cleaning or performing any
maintenance. When it is not in use for long periods, it is advisable to remove the plug from the
power socket. Do not use chemical solvents (such as benzene, alcohol or gasoline) as they
may cause irreversible damage to the unit.
Filter Cleaning
The Air-inlet may gather dust easily, please clean it often with a soft, damp cloth. If the
lter is covered by dust, the airow and the performance of the unit will be affected, it may
even cause damage to the unit. We recommend that you regularly clean the filters. The
dehumidier must be disconnected from the socket before maintenance and the lters must
be allowed to fully dry before re use.
CARE AND MAINTENANCE
Remove the filters from the unit, and tap the dust away.
Clean the carbon filter and the mesh filter with a vacuum cleaner or soft-brush.
If dirt and grease is accumulated wash the mesh filter in hot soapy water.

is damaged, power the unit off and unplug it immediately. Contact an electrician or service
centre for repairs; do not attempt to repair the unit yourself.
FREQUENTLY ASKED QUESTIONS
Why doesn’t the unit work /or stops suddenly?
The water tank may be full or displaced. To retore: empty the tank and carefully place the tank
back in the unit.
Amount of water collected and size of the tank
1) When you first use your dehumidifier,it will work harder to reduce the room humidity down
to 50%RH (default mode or the desired humidity set, if setting have been changed).This is the
time when it will produce the most water and as such will require emptying most frequently
(even 2-3 times /day). As the room becomes dryer, the dehumidifier collects less water and it
will take longer to fill the tank, this is perfectly normal. When the target relative humidity has
been reached the dehumidifier will stop collecting water and will operate for longer periods in
fan only mode, this is normal operation.The intelligent logic of your machine will save you
money.
2) Unless you are using the unit to dry clothes, we recommen to set the desired humidity to
50-60%RH
3)If you find that you still have condensation on your windows or you need to dry the air further
then the 40%RH or continuous mode can be used with fan set to turbo mode. This might well
be necessary if you have single glazed windows, the house is poorly insulated or if the
outside air temperature drops towards freezing. Using in turbo mode will add more heat to your
room and reduce your heating bill as dry air will heat quicker
4) For unoccupied properties,garages and etc.,use 60-70%RH with fan in turbo or sleep
mode according to your needs. That will ensure minimum power consumption while prevent
moisture related issues.

temperature has dropped
significantly and the
windows are colder
Set the dehumidifier to 40%RH
and run for longer
I can not
remove the
condensation
from my
window,even
in continuous
or laundry
function
The surface temperature
of the windows is too
low for a dehumidifier to
prevent condensation.
Common with single
glazed windows or poorly
insulated houses when the
outside temperature drops
below ooC
Keep running the dehumidifier
on Laundry 24hours a day and
if the air temperature outside
increases the condensation on
windows may clear
Dehumidifier
is blowing out
warm air
The dried air is passes
over a heating element
before it is blown into
the room as part of the
dehumidification proces
This is normal and helpful
especially in the cold weather,a
dehumidifier is not an air
cooler.
