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, 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.
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.

"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).
