4 MAINTENANCE
It is good practice to periodically clean both the internal
and external parts of the appliance. This guarantees its
proper operation and durability.
Carry out periodic maintenance of the appliance in
accordance with the regulations in force.
Maintenance must be carried out by qualified technical
personnel.
4.1
Cleaning the indoor unit
ATTENTION ELECTRIC DANGER
– Before cleaning or maintenance, always
switch off the air conditioner and disconnect
it from the power supply.
– DO NOT replace blown fuses with fuses of
different amps because this could damage
the circuit or cause a fire hazard.
– Check that all cables are connected
correctly. Incorrectly connecting cables can
create a fire or electrocution risk.
CAUTION
– Use only a soft, dry cloth to clean the unit.
If the unit is particularly dirty, you can use a
cloth moistened in warm water.
– Check that the drain pipe is installed
according to the instructions. If it is not,
water leaks may occur resulting in material
damage and fire and electrocution risks.
IT IS PROHIBITED TO
– use chemicals or chemically treated cloths
to clean the unit;
– use benzene, thinners, polishing powders
or other solvents to clean the unit.
These substances can cause cracking or
deformation of the plastic surface;
– use water at temperatures above 40°C to
clean the front panel. Very hot water can
cause the panel to deform or discolour.
4.2
Cleaning the air filter
The filter stops dust and other particles from entering the
indoor unit. A build-up of dust can reduce the efficiency
of the air conditioner. For optimal efficiency, clean the air
filter every two weeks or, if the zone is very dusty, more
frequently. If the filter is very clogged and cannot be
perfectly cleaned, it is advisable to replace it.
WARNING
It can be dangerous to remove and clean
the filter . Disassembly and maintenance
operations must be carried out by certified
technical personnel.
CAUTION DANGER
When removing the filter, avoid touching the
metal parts of the unit. Sharp metal edges can
be sharp.
IT IS PROHIBITED TO
dry the filter by exposing it to direct sunlight.
