7.1 Precautions for maintenance and
service
WARNING: System contains refrigerant
under very high pressure.
The system MUST be serviced by qualified persons only.
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, suction grille, air
outlet and outside panels.
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.
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.
WARNING
Be careful with ladders when working in high places.
7.2 Cleaning the air filter and air outlet
7.2.1 To clean the air outlet
WARNING
Do NOT let the indoor unit get wet. Possible
consequence: Electric shock or fire.
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.
Clean with a soft cloth. If it is difficult to remove stains, use water or
a neutral detergent.
7.2.2 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).

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.

4 Re-attach the air filter. Align the 2 hanger brackets and push
the 2 clips in their place and pull the cloth if necessary.
