■ Beware of fire in case of refrigerant leakage.
If the air conditioner is not operating correctly, i.e. not generating
cool or warm air, refrigerant leakage could be the cause. Consult
your dealer for assistance. The refrigerant within the air
conditioner is safe and normally does not leak. However, in the
event of a leakage, contact with a naked burner, heater or
cooker may result in generation of noxious gas. Do not longer
use the air conditioner until a qualified service person confirms
that the leakage has been repaired.

off and remove the power cord. Otherwise, an electric shock and
injury may result.
■ To avoid electric shocks, do not operate with wet hands.
■ Do not place objects that are susceptible to moisture directly
beneath the indoor or outdoor units. Under certain conditions,
condensation on the main unit or refrigerant pipes, air filter dirt
or drain blockage may cause dripping, resulting in fouling or
failure of the object concerned.
■ Do not place burners or heaters in places exposed to the air flow
from the unit as this may impair combustion of the burner or
heater.
■ Do not allow children to climb on the outdoor unit and avoid
placing objects on the unit. Injury may result if the unit becomes
loose and falls.
