leakage or short circuit.

PRECAUTIONS FOR RELOCATION

OR REPAIRING

CAUTION

Never perform any

modification. Contact

your dealer for repairing.

Improper repairing may lead to

water leakage, electric shock

or fire. Normally the refrigerant

does not leak. But if it leaks

and contacts fire such as

fan heater, space heater

or cooking heater, it may

produce toxic chemicals. When

repairing refrigerant leakage,

determine the service with the

service staff that the repair has

been finished without fault.

clogging of drain pipe may damage

them through dew dropping.

When the refrigerant leaked

accidentally, turn off the stove,

or other, and ventilate air sufficiently.

Do not use a spray

containing flammable gas

near the indoor unit.

Otherwise, the unit may stop

abnormally due to a false detection.

Do not turn off the power

breaker except during

maintenance and inspection.

As refrigerant leakage cannot

be detected, a fire may result.

When the power breaker

is on, pay attention to the

rotation of the fan.

If the refrigerant sensor detects a

refrigerant leak, the fan will rotate

automatically and may cause an injury.

If the "Refrigerant sensor

replace time has passed."

message appears on the remote

control, replace the sensor.

If you continue to use the refrigerant

sensor even after its replacement

period has passed, a fire may result

if the refrigerant leaks.
