• Incomplete installation could cause a personal injury due to fire, electric shock, the unit falling or a leakage of water.
• When installed in an insufficient strong place, the unit could fall causing injured.
• Incomplete connecting and fixing could cause fire.
• 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.
• The use of defective par ts could cause an injury or leakage of water due to a fire, electric shock, the unit f alling, etc.
• If there is a defect in the drainage/piping work, water could drop from the unit and household goods could be wet and damaged.
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.
• If the electrical part cover if the indoor unit and/or the service panel if the outdoor unit are not attached securely, it could result in a fire or electric shock due to dust, water , etc.
Could lead to serious injury in particular environments when operated incorrectly.

1. Selection of the best location
1) Indoor unit
• There should not be any heat source or steam near the unit.
• There should not be any obstacles to prevent the air circulation.
• A place where air circulation in the room will be good.
• A place where drainage can be easily obtained.
• A place where noise prevention is taken into consideration.
• Do not install the unit near the door way.
• Ensure the spaces indicated by arrows from the wall, ceiling, or other obstacles.
• The indoor unit must keep the maintenance space.
2) Outdoor unit
• If an awning is built over the unit to prevent direct sunlight or rain exposure, be careful that heat radiation from the condenser is not restricted.
• There should not be any animals or plants which could be affected by hot air discharged.
• Ensure the spaces indicated by arrows from the wall, ceiling, fence or other obstacles.

Take enough distance
• This air-conditioner uses a drain pump.
• Horizontly install the unit using a level gauge.
• During the installation, care should be taken not to
damage electric wires.
2. Ceiling opening dimensions and hanging bolt location
NOTE:
• Thoroughly study the following installation locations:
1. In such places as restaurants and kitchens, considerable amount of oil steam and flour adhere to the turbo fan, the fin of the heat exchanger and the drain pump, resulting in heat exchange reduction, spraying, dispersing of water drops, drain pump malfunction, etc. In these cases, take the following actions:
• Make sure that the ventilation fan for smoke-collecting hood on a cooking table has sufficient
capacity so that it draws oily steam which should not flow into the suction of the air conditioner.
• Make enough distance from a cooking room to install the air conditioner in such a place where it may
not suck in oily steam.
2. Avoid installing air conditioner in such circumstances where cutting oil mist or iron powder is in suspension in factories, etc.
3. Avoid places where inflammable gas is generated, flows in, is stored or vented.
4. Avoid places where sulfurous acid gas or corrosive gas is generated.
5. Avoid places near high frequency generators.

• Tighten the nut and bolt to prevent unit falling.
4. Remote Controller Installation
• Although the room temperature sensor is in the indoor unit, the remote controller should be installed in such places away from direct sunlight and high humidity.
Installation of the remote controller
• Select places that are not splashed with water.
• Select control position after receiving customer approval.
• The room temperature sensor is built in the indoor unit.
• This remote controller equipped with liquid crystal display. If this position is higher or lower, display is difficult to see.(The standard height is 1.2 ~ 1.5m high)
Routing of the remote controller cord
• Keep the remote controller cord away from the refrigerant piping and the drain piping.
• To protect the remote controller cord from electrical noise, place the cord at least 5cm away from other power cables (audio equipment, television set, etc.)
• If the remote controller cord is secured to the wall, provide a trap at the top of the cord to prevent water droplets
from running.
