10 Maintenance and service
10.1 Precautions for maintenance and service
CAUTION
See "4User safety instructions"[420] 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 and air outlet.
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.
10.2 Cleaning the air filter and air outlet
CAUTION
Turn off the unit before cleaning the air filter and air outlet.
NOTICE
▪ Do NOT use gasoline, benzene, thinner polishing powder or liquid insecticide.
Possible consequence: Discoloration and deformation.
▪ Do NOT use water or air of 50°C or higher. Possible consequence: Discoloration
and deformation.
10.2.1 To clean the air filter
When to clean the air filter:
▪ Rule of thumb: Clean every 6 months. If the air in the room is extremely
contaminated, increase the cleaning frequency.
▪ Depending on the settings, the user interface can display the TIME TO CLEAN AIR
FILTER notification. Clean the air filter when the notification is displayed.
▪ If the dirt becomes impossible to clean, change the air filter (= optional
equipment).
How to clean the air filter:
1 Remove the air filters by pulling their cloth upward (in case of rear suction) or
backward (in case of bottom suction).
