CAUTION		properly to drain water. Arrange the drain hose
		to ensure smooth drainage.

Installation

•If the refrigerant gas leaks during the installation, ventilate the area immediately.

−−Such leakage it can be harmful for your health.

•Always check for gas (refrigerant) leakage after installation or repair of product.

−−Low refrigerant levels may cause product failure.

•Keep the product level, even when installing it.

−−This will help to avoid vibration or water leakage.

•Use two or more people to lift and transport the product.

−−This will help to avoid personal injury.

•Installation work must be performed in accordance with the National Electric Code by qualified and authorized personnel only.

debris accumulate around the unit. Leaves are a hotbed for small animals, which can enter the unit. Once inside the unit, these animals can lead to the unit malfunctioning, and end up causing in smoke or fire when they make contact with electrical parts.

−−There is a risk of fire or electric shock.

•Do not install the product where it will be exposed to sea wind (salt spray) directly.

−−This can cause corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause product malfunction or inefficient operation.

−−Incomplete drainage may lead to water damage done to the building, furniture, etc. If no water is discharged from the drainpipe while the air conditioner or heat pump is in the cooling mode, it may be because the drainpipe has become clogged with dust or dirt, and could result in water leakage

in the indoor unit. In such a situation, stop operating the air conditioner or heat pump and contact the dealer.
