INSTALLATION OF THE AIR CONDITIONING SYSTEM.
Failure to observe the instructions for installation, use and
operation described in this Manual may result in operating
failure including potentially serious faults, or even the
destruction of the air conditioning system.
It is assumed that the air conditioning system will be installed
and maintained by responsible personnel trained for the
purpose. The customer should include all the safety, caution
and operating signs in the native language of the personnel
responsible.

Do not carry out maintenance or inspection work yourself. This work
must be carried out by qualified service personnel with suitable tools
and resources for the work.

repel water. As a result, the condensate water will splash out
of the collection tray and into the electrical box. Water leaks or
electrical faults may eventually be caused.
Do not install the unit in a place where the current of expelled
air directly affects animals or plants as they could be adversely
affected.
Do not reconstruct the unit. Water leakage, fault, short circuit or
fire may occur if you reconstruct the unit by yourself.
Please use an earth wire. Do not place the earth wire near
water or gas pipes, lightning conductors, or the earth wire of
a telephone. Improper installation of earth wiring may cause
electric shock or fire.
Should an abnormal situation occur (like a burning smell),
please stop operating the unit and turn off the circuit breaker.
Fire may occur if you continue to operate the unit in an
abnormal situation.
Please contact your agent if you need to remove and reinstall
the unit. Electric shock or fire may occur if you remove and
reinstall the unit improperly by yourself.
If the power supply cord is damaged, it must be replaced with
the special cord obtainable at authorized service/parts centres.
Please consult with your dealer if the air conditioner does not
cool, since refrigerant leakage may be considered as one of
the causes. The refrigerant gas used in the air conditioner is
harmless. However, harmful by-products may be generated if
the refrigerant gas leaks into the room and enters in contact with
fire or a source of heat such as a stove heater. In the event of a
gas leakage, immediately stop the air conditioner, open doors
and windows to ventilate the room thoroughly and contact your
dealer.
