CAUTION

Do NOT operate the system when
using a room fumigation-type
insecticide. Chemicals could collect in
the unit, and endanger the health of
people who are hypersensitive to
chemicals.

CAUTION

NEVER expose little children, plants or
animals directly to the airflow.

WARNING

Do NOT place a flammable spray
bottle near the air conditioner and do
NOT use sprays near the unit. Doing
so may result in a fire.

Maintenance and service (see

CAUTION: Pay attention to the fan!

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

Make sure to turn OFF the main switch
before executing any maintenance
task.

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.

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
electrical shock and injury may result.

WARNING

Be careful with ladders when working
in high places.

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.

CAUTION

Turn off the unit before cleaning the air
outlet.

WARNING

Do NOT let the indoor unit get wet.

Possible consequence: 

Electrical

shock or fire.

▪ The refrigerant in the system is safe

and normally does NOT leak. If the
refrigerant leaks in the room, contact
with a fire of a burner, a heater or a
cooker may result in a harmful gas.

▪ Turn OFF any combustible heating

devices, ventilate the room and
contact the dealer where you
purchased the unit.

▪ Do NOT use the system until a

service person confirms that the
portion where the refrigerant leaks is
repaired.
