Danger!
Danger of electric shock.
Do not clean the unit with water.
Warning!
Danger of breakdowns or malfunction.
Do not use gasoline, benzine, thinner or

the coating of the unit.

Hot water over 40ºC may cause discoloring or
deformation.
10.1 Cleaning the Remote Controller
• Wipe the controller with a dry cloth. Do not use water
to clean the remote controller.
• Do not use glass cleaners or chemical cloths.
10.2 Cleaning the Indoor Unit
• Wipe the outer part of the unit with a soft and dry
cloth.
• For difficult stains, use a neutral detergent diluted in
water. Eliminate the excess of water form the cloth
before wiping. Leave the unit clean from any
detergent.
10.3 Cleaning the Air Filters
The air filter traps the dust circulated from the room
into the indoor unit.
If the filter becomes blocked, the air conditioner's
efficiency will be reduced, the compressor could be
damaged and the indoor unit's heat exchanger coil could
freeze up.
Clean the air filter regularly to prevent this from
happening. In order to do so:
• Remove the air filters by slightly pushing up the center
tab until it is released from the stopper and remove
the filter downwards.
• Clean the filter removing the dust or the dirt using a
vacuum cleaner or cleaning them with cold water.
• Ensure that the filters are dried completely (dry in the
shade) before putting them back into the unit. The
activated carbon filters (where fitted) can be
reactivated by placing in direct sunlight. If strange
odours are still smelt replace with new. If strong
odours continue to be a problem, contact your after
sales service provider to fully deep clean the unit.
• Attach the filter correctly and make sure it is
completely fixed behind the stopper. If the right and
left filters are not properly fixed, this could cause a
malfunction.
Warning!
Danger of breakdowns or malfunction.
Do not attach perfume systems, anti-odour
systems etc. in the filter or in the inside air
return.
This can damage and soil the heat exchanger
coil. If necessary, install these systems at the
unit's outlet point and ensure they only run when
the fan is on.
10.4 Cleaning the Outdoor Unit
• Wipe the outer part of the unit with a dry cloth.
• Occasionally remove dust and leaves from the inlet
surface.
• Periodically clean the heat exchanger fins with a soft
brush when the unit is located in a dusty environment.
• Occasionally check the base of the outdoor unit.
Danger of injury and physical damage!
A damaged or deteriorated base could make the
unit fall down and cause physical or material
damage.
Danger of injury and physical damage!
Except for servicing or replacement, do not
dismantle the outdoor unit outlet. Exposing the
fan can be very dangerous.
Note!
We advise you to contact a reliable air
conditioner specialist or the Vaillant Group
Technical Service to contract a preventative
maintenance service. This will help to prolong the
life of your equipment and improve its
performance.
