Warning:

Carefully read the labels affixed to the main unit.

• Perform the installation securely referring to the installation manual. Incomplete installation could cause a personal injury due to fire, electric shock, the unit falling or leakage of water.

• Perform electrical work according to the installation manual and be sure to use an exclusive circuit. If the capacity of the power circuit is insufficient or there is incomplete electrical work, it could result in a fire or an electric shock.

• Attach the electrical part cover to the indoor unit and the service panel to the outdoor unit securely. If the electrical part cover in the indoor unit and/or the service panel in the outdoor unit are not attached securely, it could result in a fire or an electric shock due to dust, water, etc.

• Be sure to use the part provided or specified parts for the installation work. The use of defective parts could cause an injury or leakage of water due to a fire, an electric shock, the unit falling, etc.

• Ventilate the room if refrigerant leaks during operation. If the refrigerant comes in contact with a flame, poisonous gases will be released.

Caution:

• Perform grounding. Do not connect the ground wire to a gas pipe, water pipe arrester or telephone ground wire. Defective grounding could cause an electric shock.

• Do not install the unit in a place where an inflammable gas leaks. If gas leaks and accumulates in the area surrounding the unit, it could cause an explosion.

• Install a ground leakage breaker depending on the installation place (where it is humid). If a ground leakage breaker is not installed, it could cause an electric shock.

2. Selecting the installation location

2.1. Indoor unit

• Where airflow is not blocked.

• Where cool air spreads over the entire room.

• Where it is not exposed to direct sunshine.

• At a distance 1 m or more away from your TV and radio (to prevent picture from being distorted or noise from being generated).

• In a place as far away as possible from fluorescent and incandescent lights (so the infrared remote control can operate the air conditioner normally).

2.2. Outdoor unit

• Where it is not exposed to strong wind.

• Where airflow is good and dustless.

• Where it is not exposed to rain and direct sunshine.

• Where neighbours are not annoyed by operation sound or hot air.

• Where rigid wall or support is available to prevent the increase of operation sound or vibration.

• Where there is no risk of combustible gas leakage.

• When installing the unit at a high level, be sure to fix the unit legs.

• Where it is at least 3 m away from the antenna of TV set or radio. (Otherwise, images would be disturbed or noise would be generated.)

• Perform the drainage/piping work securely according to the installation manual. If there is a defect in the drainage/piping work, water could drop from the unit and household goods could be wet and damaged.

• Fasten a flare nut with a torque wrench as specified in this manual. When fastened too tight, a flare nut may broken after a long period and cause a leakage of refrigerant.

• Where the air filter can be removed and replaced easily.

Warning: Mount the indoor unit into a ceiling strong enough to withstand the weight of the unit.

• Install the unit horizontally.

Caution: Avoid the following places for installation where air conditioner trouble is liable to occur.

• Where there is too much machine oil.

• Salty environment as seaside areas.

• Hot-spring areas.

• Where sulfide gas exists.

• Other special atmospheric areas.

3. Selecting an installation site & Accessories

• Select a site with sturdy fixed surface sufficiently durable against the weight of unit.

• Before installing unit, the routing to carry in unit to the installation site should be determined.

• Select a site where the unit is not affected by entering air.

• Select a site where the flow of supply and return air is not blocked.

• Select a site where refrigerant piping can easily be led to the outside.

• Select a site which allows the supply air to be distributed fully in room.

• Do not install unit at a site with oil splashing or steam in much quantity.

• Do not install unit at a site where combustible gas may generate, flow in, stagnate or leak.

• Do not install unit at a site where equipment generating high frequency waves (a high frequency wave welder for example) is provided.

• Do not install unit at a site where fire detector is located at the supply air side. (Fire detector may operate erroneously due to the heated air supplied during heating operation.)

• When special chemical product may scatter around such as site chemical plants and hospitals, full investigation is required before installing unit. (The plastic components may be damaged depending on the chemical product applied.)

• If the unit is run for long hours when the air above the ceiling is at high temperature/ high humidity (due point above 26 °C), due condensation may be produced in the indoor unit. When operating the units in this condition, add insulation material (1020 mm) to the entire surface of the indoor unit to avoid due condensation.

3.1. Install the indoor unit on a ceiling strong enough

to sustain its weight
