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
electrical shock and injury may result.
WARNING
Be careful with ladders when working in high places.
NOTICE
When cleaning the heat exchanger, make sure to remove
the electronic components above it. Water or detergent
might deteriorate the insulation of electronic components
and result in burnout of these components.
DANGER: RISK OF ELECTROCUTION
Disconnect the power supply for more than 10 minutes,
and measure the voltage at the terminals of main circuit
capacitors or electrical components before servicing. The
voltage MUST be less than 50 V DC before you can touch
electrical components. For the location of the terminals,
see the warning label for persons performing service and
maintenance.

"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:
1 Open the suction grille . Simultaneously slide all knobs (2 for
class 35+50, 3 for class 60~140) in the direction of the arrow
