IMPORTANT
Installer and Users please note:
These instructions should be read carefully and left with the user of the
product for future reference.
BEFORE USE
You must inspect the product including its cable and plug for any signs of
damage. If the product is damaged, DO NOT use it, and contact your
supplier immediately.
INSTALLATION
Place the appliance on a firm, flat level surface.
If continuous drainage is to be used, remove the bung from the drainage
port (towards the bottom of the tank), and connect a drainage hose to the
port. Use a hose with an internal diameter of 12mm (½"). Make sure that
the hose runs downwards throughout its entire length, and has no kinks.
Otherwise the drainage will not work.
Make sure that the bucket is fitted correctly into the housing.
OPERATION
•Plug the mains lead into a 13 Amp mains socket.
•If connecting via an extension lead, make sure that the lead is rated at 6
Amps, and that it is fully unwound.
•Place the appliance on a firm flat level surface.

•Switch the appliance on at the mains socket. Then press the power
ON/OFF button to turn the unit ON. The appliance will wait for 3 minutes
whilst the refrigerant settles before starting to operate, this is to extend the
life of the compressor.
•Using the + and - buttons, set the required humidity level on the display.
The level can be set between 30% and 80% in 1% increments. The
appliance will remove humidity from the air whenever the humidity level is
higher that the set level.
•After a delay of 5 seconds, the display changes to showing the present
room humidity level.
•To select continuous operation, keep pressing the - button until the
display reaches 30%, and then press the - button once more. The display
will show CO and it will continuously remove humidity from the air
regardless of the humidity level. Press the + button to stop continuous
operation.
•Take particular care if selecting continuous operation and when
continuous drainage is being used. It will lead to a reduction of humidity
levels; which, if the humidity becomes too low, may lead to the cracking of
delicate wooden items.
•If operating at an ambient temperature below 10 °C, the internal heat
exchanger will drop below 0 °C, causing ice to form. If this happens, the
appliance will automatically defrost: when this happens the DEFROST
indicator will illuminate. When defrosting is complete the indicator will
extinguish and the dehumidification process will resume.
•Unplug the appliance from the mains when not in use. (Do not
disconnect whilst still operating, press the ON/OFF button to switch off the
appliance first)
•Check the appliance regularly for damage and cease using it
immediately if any damage to the product, the cable or the mains plug is
found.
•The appliance operates best if it is in an enclosed area. Close all doors
and windows, and eliminate sources of additional humidity, such as
cooking, clothes drying. Cover fish tanks.
•The most comfortable setting for the humidity level is around 50%.

EMPTYING THE COLLECTED WATER
•If not using a drainage hose, empty the bucket when the display shows
"E4" and the water full indicator lights up.
•Open the lower front door.
•Pull the bucket outwards
•Empty the water down a drain.
STORAGE
If the appliance is not going to be used for a long time:
1. Empty and clean the bucket.
2. Unplug from the mains
3. Clean the appliance
4. Store in its original packaging

OPERATING COSTS
At time of going to press, the average cost of electricity is £0.13 per unit
(kilowatt-hour). The amount you are being charged will be shown on your
electricity bill. At this cost, the appliance will cost £0.12 per hour to run on
the "continuous" setting. If the humidistat is used, the operating costs will
be lower.
FLUORINATED GASES
The appliance contains refrigerant gas which is subject to control under
the Fluorinated Greenhouse Gases Regulations 2009. It is a criminal
offence knowingly to allow the refrigerant gas to leak to the atmosphere. It
is also a criminal offence to work on the product unless suitably qualified.
PAT TESTING
When used in a workplace, this product should be safety-tested yearly by
a qualified electrician (PAT Tested).
We recommend that it is PAT tested regularly when used in a domestic
environment.

MAINTENANCE
•Before cleaning, turn the appliance off, and disconnect from the mains
supply. The appliance may then be cleaned using a damp cloth with a
drop of washing-up liquid to remove any dust or dirt from the case. Do no
use stronger detergents or solvents as these may damage the surface
finish.
•Clean the inside of the bucket to prevent the build-up of bacteria.
•Using a dry 1" (25mm) paint-brush, remove any dust from the grilles.
The filter should be cleaned every fortnight (or more often if the
atmosphere is particularly dusty).
To clean the filter, open the lower door at the front, and remove the filter
by pulling downwards.
Clean the filter with a vacuum cleaner, or, if it is very dirty, wash in hand-
hot water with a small amount of detergent.
To replace the filter, make sure that it is the correct way round - the
narrow web (shown by the arrow) should be to the outside. Make sure that
the filter slides into the guides.

Page 7
Push the filter upwards, until it fits in place, with the wide web resting on
the top of the water container.
•If the mains lead is damaged, it must be replaced by the manufacturer or
an authorised service centre. If the mains plug needs to be replaced,
proceed as follows:
•Connect the brown wire to the terminal
labelled "L".
•Connect the blue wire to the terminal
labelled "N".
•Connect the green/yellow wire to the
terminal labelled with the earth symbol
or "E".
•Make sure that the cord-grip is
positioned correctly (over the outer
sheath of the cable) and it fully
tightened.
•If the plug is fitted with a 13 A fuse, replace it by a 5 A fuse.

FAULT FINDING
Appliance does not operate when switched on:
•There is a 3 minute delay before the compressor starts. This is to protect
the compressor.
Appliance stops operating and “E4”is displayed on panel along with
the "TANK FULL" indicator lights.
•Bucket is full of water - empty the water as shown on page 6. Do not
drink the water (it may be used for watering plants).
•Bucket is not replaced properly. Ensure that the bucket is correctly
aligned with the housing.
Appliance stops operating and DEFROST indicator illuminates.
•This happens if the temperature is lower than 10 °C, and ice begins to
form on the internal heat exchanger. The defrost cycle will last for a few
minutes, and then operation will resume.
Appliance operates intermittently.
•The humidity in the room has reached the level set on the humidistat
control.
Very little water is extracted.
•There is very little humidity in the air (this happens during dry sunny
weather, and also during very cold weather). Condensation on windows is
caused by the difference between indoor and outdoor temperatures, and
is not a good indicator of the level of humidity.
The room remains humid and little water is extracted
•The humidity setting is too high, press the - button to reduce the required
humidity level.
•The area to be dehumidified is too large
FAULT CODES
E3 Humidity sensor fault.
E5 Pipework temperature sensor fault
If either of these faults is detected, stop the appliance by pressing the
power button. When it has stopped, switch off at the mains socket and
wait 3 minutes. Switch back on, and restart the appliance. If the fault
repeats contact your dealer.
