Caution.
Ask your dealer or specialized subcontractor for
installation.
Conducting installation work by yourself improperly may cause
a fire, electric shock or water leakage.
1.1 Installation.
The Installation Manual details the suggested installation method.
Any structural alteration necessary for installation must comply with

If the refrigerant leaks, hypoxia accident may caused.
For the countermeasure to be taken, consult your dealer.
The unit should be securely installed.
If the unit is loosely mounted, it may fall, causing injury.

1 ) Unit
Warning.
Please pay attention to the refrigerant (Freon gas).
A non flammable, non-toxic, odourless refrigerant is used for this air
conditioner.
The refrigerant is collected on the floor side in the room because the
specific gravity are larger than air. And, it causes the hypoxia accident.
When the refrigerant gas leaks by any chance, the user must ventilates
air enough by stopping the drive of the unit and opening the door.
Warning.
The unit must be installed on stable, level surface in a
place where there is no accumulation of snow, leaves or

You may fall down or the item may fall, causing injury.
The heating of refrigerant is noted.
When the refrigerant touches the fire etc., it was decomposed and
a poisonous gas is generated.
Do not use the welding machine etc., in the room close up of the
installation of the air conditioner.
Install drain piping (hose) according to
Installation Manual to ensure proper drainage.
Improper drain piping (hose) may cause water
leakage and damage to furniture or other possessions.
Use breaker or fuse with proper capacity.
Using a wire or copper wire instead of proper capacity can cause fire
or trouble.
Other appliances connected to the same line could cause an overload.
When installing at a watery place, provide an electric
leak breaker.
Failure to mount the electric leak breaker may cause electric shock.
The unit must be properly earth connected.
