It is dangerous to inspect the unit while the fan is running.

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

cloth.

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 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:
NOTICE
Do NOT use water of 50°C or higher. Possible
consequence: Discoloration and deformation.
