1. The following should be always observed for safety

	• Please report to or take consent by the supply authority before connecting to the system.				<![if ! IE]> <![endif]>ENGLISH
	• Be sure to read "THE FOLLOWING SHOULD BE ALWAYS OBSERVED FOR SAFETY" before
	installing the air conditioner.
	• Be sure to observe the cautions specified here as they include important items related to safety.
	• The indications and meanings are as follows.
	WARNING		Could lead to death, serious injury, etc.
	CAUTION		Could lead to serious injury in particular environments when operated incorrectly.
	• After reading this manual, be sure to keep it together with the instruction manual in a handy place .
			WARNING

Do not install it yourself (customer).

•Incomplete installation could cause injury due to fire, electric shock, the unit falling or a leakage of water. Consult the dealer from whom you purchased the unit or special installer.

Install the unit securely in a place which can bear the weight of the unit.

•When installed in an insufficient strong place, the unit could fall causing injured.

Use the specified wires to connect the indoor and the outdoor units securely and attach the wires firmly to the terminal board connecting sections so the stress of the wires is not applied to the sections.

• Incomplete connecting and fixing could cause fire.

Check that the refrigerant gas do not leak after installation is completed.

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 a 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 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.

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, electric shock, the unit falling, etc.

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.

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.

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.

2.Installation of Indoor, Outdoor Unit

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.

Level gauge

CAUTION

•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.

•Select and mark the position for fixing bolts and piping hole.

•Decide the position for fixing bolts slightly tilted to the drain direction after considering the direction of drain hose.

•Drill the hole for anchor bolt on the wall.

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.

Air conditioner

Take enough distance

Use the ventilation fan for smoke-collecting hood with sufficient

capacity.

Cooking table

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.

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.
