Items to be Strictly Observed
WARNING
• 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.
• In the case of using a load breaker provided with a fuse, make sure that
the capacity of the fuse is correct.
Use of an ordinary conductive wire may cause malfunctions or fire.
• Do not use the power supply breaker to start or stop the air conditioner.
Otherwise, fire or water leakage may result.
Furthermore, the fan will rotate abruptly if power failure compensation is enabled, which
may result in injury.
• Be sure to earth the unit.
Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead.
Imperfect earthing may result in electric shocks or fire. A high surge current from
lightning or other sources may cause damage to the air conditioner.
• When the air conditioner is malfunctioning (giving off a burning odour,
etc). turn off the power and contact your local dealer.
Continued operation under such circumstances may result in a failure, electric shocks or
fire hazards.
• Consult your local dealer regarding what to do in case of refrigerant
leakage.
When the air conditioner is to be installed in a small room, it is necessary to take proper
measures so that the amount of any leaked refrigerant does not exceed the
concentration limit in the event of a leakage.
Otherwise, this may lead to an accident due to oxygen depletion.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks or fire.
• Consult the dealer if the air conditioner submerges owing to a natural
disaster such as a flood or typhoon.
Do not operate the air conditioner in that case or otherwise a malfunction, electric shock
or fire may result.
• Be sure to use a dedicated power supply for the air conditioner.
The use of any other power supply may cause heat generation, fire or product failures.
