10.1 Cleaning the Indoor Unit
• Wipe the outer part of the unit with a soft dry cloth.
• Occasionally remove dust from the inlet surface.
10.2 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.
• Remove the dust or the dirt in the filters using a
vacuum cleaner or cleaning them with lukewarm water
(approx. 30ºC).
• Ensure that the filters are dried completely 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.
Warning
!
Do not use hot water to clean the filters.
Warning
!
Do not leave the filters to dry near fire.
Warning
!
Do not force the filters when removing or
installing the in the unit.
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.
10.3 Cleaning the Outdoor Unit
• Wipe the outer part of the unit with a soft 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.
