CAUTIONS FOR INSTALLATION

The system should be applied to places as

office, restaurant, residence and the like.

The system should be installed by your

dealer or a professional installer.

When you need some optional devices such as a hu-
midifier, electric heater, etc., be sure to use the products
which are recommended by us. These devices should
be attached by a professional installer.

Application to inferior environment such as an engi-

neering shop, could cause equipment malfunction and

serious injury or death.

Installation by yourself is not encouraged because
it could cause such problems as water leakage,
electrical shock or fire accident by some improper
handing.

Installation by yourself is not encouraged because it
could cause such problems as water leakage, electrical
shock or fire accident by some improper handing.

Do not install nearby the place where may

have leakage of flammable gas.

Depending on the place of installation, a

circuit breaker may be necessary.

Drain pipe should be arranged to provide a

positive draining.

If the gas leakes and gathers around, it may cause the

fire.

Unless the circuit breaker is installed, it could

cause elecrical shocks.

Where strong winds may prevail, the

system should be fixed securely to prevent

a collapse.

Install on the place where can endure

the weight of air conditioner.

Make sure the system is grounded.

If the pipe is arranged improperly, furniture or the

likes may be damaged by leaked water.

Bodily injury could result by a collapse.

Bodily injury could result by a careless installation.

Grounding cable should never be connected to a gas
pipe, city water pipe, lightning conductor rod or
grounding cable of telephone. If the grounding cable
is not set properly, it could cause electric shocks.

CAUTIONS FOR OPERATION

You should refrain from exposing your body

directly to cool wind for a long time.

Do not poke the air inlet or outlet with a

bar, etc.

When any abnormal condition (scorching smell or oth-
ers) is found, stop the operation immediately and turn
off the power switch. Then consult your dealer.

It could affect your physical condition or cause some

health problems.

Since the internal fan is operating with a high

speed, it could cause an injury.

If you continue the operation without removing the

cause, it could result in a trouble, electric shock or fire.

The system should never be used for any
other purposes than intended such as for
preservation of food, flora and fauna, pre-
cision deices or work of art.

Do not handle switches with a wet hand.

Combustion apparatus should not be placed
allowing a direct exposure to wind of air con-
ditioner.

Incomplete combustion could occur on the apparatus.

It could cause electric shocks.

It could cause deterioration of food or other problems.
