WARNING

CAUTION

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

humidifier, 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

engineering  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.

WARNING

CAUTIONS FOR TRANSFER OR REPAIR

Modification of the system is strictly prohibited. When the system needs a

repair, consult your dealer.

When the air conditioner is relocated, contact your dealer or a professional

installer.

Improper practice of repair could cause water leakage, electric shock or

fire.

Improper practice of installation could cause water leakage, electric shock

or fire.
