7 Maintenance and service
7.1 Precautions for maintenance and
service
CAUTION
See "3 User safety instructions" [4 5] to acknowledge all
related safety instructions.
NOTICE
NEVER inspect or service the unit by yourself. Ask a
qualified service person to perform this work. However, as
end user, you may clean the air filter, suction grille, air
outlet and outside panels.
NOTICE
Maintenance MUST be done by an authorised installer or
service agent.
We recommend performing maintenance at least once a
year. However, applicable legislation might require shorter
maintenance intervals.
NOTICE
Do NOT wipe the controller operation panel with benzine,
thinner, chemical dust cloth, etc. The panel may get
discoloured or the coating peeled off. If it is heavily dirty,
soak a cloth in water-diluted neutral detergent, squeeze it
well and wipe the panel clean. Wipe it with another dry
cloth.
NOTICE
When cleaning the heat exchanger, make sure to remove
the electronic components above it. Water or detergent
might deteriorate the insulation of electronic components
and result in burnout of these components.
Following symbols may occur on the indoor unit:
Symbol Explanation
