is illuminated and the dehumidifier starts in High fan and Laundry modes.
Lights up when the dehumidifier is dehumidifying.
Lights up when the internal tank is full of water and needs to be emptied or when
the tank is incorrectly fitted.
The buzzer will sound 10 times for about 5 seconds and then the
dehumidifier will stop working and only the Empty Tank light will be illuminated.
Lights up when the dehumidifier is deicing.
This is more common when the
dehumidifier is being used below 16°C, the dehumidifier will stop drying for about 7 minutes whilst it
defrosts and will then dehumidify for the next 25 minutes before defrosting again.
Press the Mode button to toggle between the following settings.
Use this mode when you want to dry washing.

When the relative humidity rises again the
dehumidifier will automatically start to collect water again.
Although the Laundry
mode aims for a lower relative humidity it will reach a point after which there will be
no more water to collect because it will not over dry the air below a point at which
the air will become uncomfortable (around 35%rh).
How does a dehumidifier work?
There are four types of dehumidifier sold to the domestic market in the UK - Compressor (this
dehumidifier), desiccant, peltier and silica gel.
A compressor based dehumidifier draws the air in from the room over a filter and passes it over some cold
coils similar to the coils on a fridge. As the coils are cold, water condenses and drips into a bucket. The
air is then reheated to room temperature and blown back out of the dehumidifier.
Why does water appear on my windows/cupboards/walls?
It is a basic law of physics that if the surface is cold enough and if there is enough water vapour in the air
then it will condense. This means in the case of windows whether they are double-glazed or not that if the
windows are cold enough and there is enough moisture in the air then condensation will occur.
Where does this water come from?
We all produce water by drying clothes indoors, the boiling of vegetables, showering, rain, calor gas
heating and making cups of tea all produces moisture. It is just an on-going process that never stops.
Can I just get rid of it by opening my windows?
This is fine on a nice summer’s day but in winter opening your windows will just result in you losing the
heat from your central heating and creating draughts. This is a waste of money and if it is raining will just
let more moisture in. You might as well just throw fivers out of the window.
Will a dehumidifier do the whole house?
A dehumidifier creates a volume of dry air in as large a space as its fan can effect (this dehumidifier can
control up to a large 5 bedroom house). After that it will be helped by the fact that damp air will always
migrate to dry places. As long as you leave all of the internal doors open a correctly sized dehumidifier
will prevent condensation and mould from appearing around the whole house.
What about the black spots of mould on my window and bathroom sealant?
Mould occurs around 68% relative humidity, condensation occurs at 100%. As you can see from this you
can have mould but still have clear windows. A dehumidifier will prevent the mould from getting any
worse and once you have cleaned the mould away, it will stop it from coming back.
Do I put it in the worst room?
You can if you like put it in the main problem area to start with and then move it somewhere more
convenient when you feel that the problem is under control. If it is just condensation on the windows that
you are worried about a dehumidifier in a central position, for example the bottom of the stairs will cure the
problem in the whole house.
Are they expensive to run?
A compressor based dehumidifier costs about 2-3p(ish) an hour to run depending on your electricity tariff.
You should take into consideration the fact that the dehumidifier will not run all the time, as it will be
controlled via its humidistat. Secondly it is very expensive to heat a damp house and you will see a
reduction in your central heating bill when you start to use your dehumidifier. The dehumidifier will work
hard for about a month as it dries the house out. After this time the dehumidifier will start to turn itself off
more often as the relative humidity settles.
What is the humidistat?
Just as you have a thermostat that you set on your central heating you have a humidistat on your
dehumidifier. This will allow the dehumidifier to turn off and on as required without you having to worry
about it.
Should I turn the dehumidifier on for just a few hours a day?
No just let the dehumidifier’s humidistat decide when to come on.
Will they help with allergies?
A dehumidifier will reduce the relative humidity in the house, which will prevent dust mites and other pests
from breeding. In this way a dehumidifier can help with allergies.
Place the dehumidifier in an upright position on a stable, flat surface.
Please ensure the unit is a safe distance away from a wall or furniture.
Please keep clothes at a safe distance of 30cm away from the air inlet or outlet to prevent water from dripping into the

Press the Power button
Select the Mode that you want to use the dehumidifier in, for most applications this will be the “Normal”
For more detail refer to page five.
To turn off press the On/Off
button again.
Where to position the dehumidifier
For best results position the dehumidifier somewhere central like a landing or a hallway. As long as the internal doors
are open the moisture will migrate naturally towards the dehumidifier to be processed.
To dry washing it is best to put the dehumidifier into a small room with some heating on. Close the door and windows
and use the dehumidifier in “Laundry” mode
. Hang the clothes so that they are not touching each other and so
that air can circulate between the clothes. Ensure that water does not drip onto the dehumidifier.
Amount of water collected
When you first use your dehumidifier it will work harder to reduce the room humidity down to 60%rh (in “Normal” mode
This is the time when it will produce the most water and need emptying most frequently. As the room
becomes dryer the dehumidifier collects less water and takes longer to fill the tank, this is perfectly normal. When the
target relative humidity has been reached the dehumidifier will stop collecting water, again this is normal.
If you find that you still have condensation on your windows or you need to dry the air further then us the “Maximum”
. This might well be necessary if you have single glazed windows or if the outside air temperature drops
towards freezing.
To operate safely
Do not insert small objects into the unit or this will damage it and cause a hazard.
Do not remove the tank when the dehumidifier is running or water may leak.
Minimum operating condition 5°C at 50%rh relative humidity.
Never use the device with a damaged power cord, plug, cabinet or control panel. Never trap the power cord or
allow it to come into contact with sharp edges.

Failing to follow the instructions may lead to the
When the water tank is full:
- An alarm signal will sound
- The dehumidifier will stop automatically.
- Empty the water tank and replace it in the correct position.
The dehumidifier
will start to work again and the compressor will start up after three minutes.
If the “Empty tank” light stays on and the unit does not start up then the tank is
not correctly fitted.
Continuous Drainage
It is possible to connect the drainage hose (included in the box) to the dehumidifier for permanent water
drainage. Simply connect the hose to the drain spout and ensure that the end of the hose is lower than the
drain opening, otherwise the water will not drain and flooding may occur.
Place the end of the drainage hose on the water outlet.
When you no longer wish to use the permanent water drainage, disconnect the drainage tube from the
device. Ensure that the water container is positioned correctly.
Switch the dehumidifier off and remove the plug from the socket before cleaning.
The exterior
Clean the exterior with a soft, dry cloth.
If the device is extremely dirty, use a mild cleaning agent. Wipe
the dehumidifier with a slightly damp cloth.
Never spray the device with water.
The air filter
When used regularly, the filter may become clogged with dust and particles. Therefore the filter should be
cleaned every two weeks. Follow these steps:
Remove the filter.
Clean the filter with a vacuum cleaner and not with water. Cleaning the filter with water will
destroy the filters anti-bacterial nano-silver properties.
Never use the device without the air filter.
If the machine will not be used for a long period of time, take the following steps:
Remove the plug from the socket and empty the container. Allow the container and the
dehumidifier to dry completely, this can take a couple of days.
Clean the air filter.
Store the device in a dust-free location away from direct sunlight, preferably covered with a
sheet of plastic.
