earth) wire or through the supply wiring.

3. Wiring must be done by a qualified electrician.

SAFETY INSTRUCTIONS

• Read this Instruction Manual carefully before using
this air conditioner. If you still have any difficulties
or problems, consult your dealer for help.

• This air conditioner is designed to give you
comfortable room conditions. Use this only for its
intended purpose as described in this Instruction
Manual.

• Never use or store gasoline or other
flammable vapor or liquid near the air
conditioner — it is very dangerous.

• This air conditioner has no ventilator
for intaking fresh air from outdoors.
You must open doors or windows
frequently when you use gas or oil
