7 Maintenance and service
7.1 Precautions for maintenance and
service
NOTICE
Maintenance MUST be done by an authorized installer or
service agent.
We recommend performing maintenance at least once a
year. However, applicable legislation might require shorter
maintenance intervals.
CAUTION
Do NOT insert fingers, rods or other objects into the air
inlet or outlet. When the fan is rotating at high speed, it will
cause injury.
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.
WARNING
Never replace a fuse with a fuse of a wrong ampere ratings
or other wires when a fuse blows out. Use of wire or
copper wire may cause the unit to break down or cause a
fire.
CAUTION
After a long use, check the unit stand and fitting for
damage. If damaged, the unit may fall and result in injury.
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.
CAUTION
Before accessing terminal devices, make sure to interrupt
all power supply.
DANGER: RISK OF ELECTROCUTION
To clean the air conditioner or air filter, be sure to stop
operation and turn all power supplies off. Otherwise, an
electric shock and injury may result.

7.2 Cleaning the air filter and air outlet
CAUTION
Turn off the unit before cleaning the air filter and air outlet.
7.2.1 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 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.
1 Remove the air filter. Pull its cloth upward (in case of rear
suction) or backward (in case of bottom suction).

2 Clean the air filter. Use a vacuum cleaner or wash with water.
If the air filter is very dirty, use a soft brush and neutral
detergent.
