n Do not store or use flammable gas or combustible

near the product.

There is risk of fire or failure of product.

n Do not use the product in a tightly closed space for a

long time.

Oxygen deficiency could occur.

n When flammable gas leaks, turn off the gas and

open a window for ventilation before turn the product on.

Do not use the telephone or turn switches on or off. There is risk of explosion or fire.

n If strange sounds, or small or smoke comes from

product. Turn the breaker off or disconnect the power supply cable.

There is risk of electric shock.

n When the product is not be used for a long time,

disconnect the power supply plug or turn off the breaker.

There is risk of product damage or failure, or unintended operation.

n Take care to ensure that nobody could step on or fall

onto the outdoor unit.

This could result in personal injury and product damage.

Ø CAUTION

n Always check for gas (refrigerant) leakage after

installation or repair of product.

Low refrigerant levels may cause failure of product.

n Install the drain hose to ensure that water is drained

away properly.

A bad connection may cause water leakage.

n Keep level even when installing the product.

To avoid vibration of water leakage.

n Do not install the product where the noise or hot air

from the outdoor unit could damage the neighborhoods.

It may cause a problem for your neighbors.

n Use two or more people to lift and transport the

product.

Avoid personal injury.

n Do not install the product where it will be exposed to

sea wind (salt spray) directly.

It may cause corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient operation.

Ø Operational

n Do not expose the skin directly to cool air for long

periods of time. (Do not sit in the draft).

This could harm to your health.

n Do not use the product for special purposes, such

as preserving foods, works of art, etc. It is a

Service manual

consumer air conditioner, not a precision refrigerant system.
