	1. The following should always be observed for safety
						<![if ! IE]> <![endif]>ENGLISH
	• Please report to or take consent by the supply authority before connection to the system.
	• Be sure to read "THE FOLLOWING SHOULD ALWAYS BE OBSERVED FOR SAFETY" before installing

	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 on the customer's site.

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 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 due not leak after installation is completed.

WARNING

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

•This product should be grounded.

•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.

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.

The means for connection to power supply shall be incorporated in the fixed wiring and have an air gap contact separation of at least 3mm in all active(phase) conductors.

2. Installation of Indoor, Outdoor unit

1) Selection of the best location

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, fence, or other obstacles.

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 discharged hot air.

•Ensure the space indicated by arrows from the wall, ceiling, fence, or other obstacles.

3) Outdoor unit Installation

Install the outdoor unit on the concrete or any solid base securely and horizontally by securing it with bolts (Ø12mm) and nuts.

If there is any vibration transmitted to the building, mount the rubber underneath the outdoor unit.

4) Refrigerant amount

Before shipment, this air conditioner is filled with the rated amount of refrigerant including additional amount required for air-purging, subject to 5m piping length. (The rated amount of refrigerant is indicated on the name plate.) But when the piping length exceeds 5 meters, additional charge is required according to the following table.

		(Unit: g)
	MODEL	REFRIGERANT CHARGE
	20K/28K/30K/40K	30 per 1m
	(Btu/h)
	50K	40 per 1m
	(Btu/h)
	80K	50 per 1m
	(Btu/h)
	100K	120 per 1m
	(Btu/h)

Example) 28K/30K

In case of 10m long pipe(one-way), the amount of refrigerant to be replenished is:

(10 - 5) x 30 = 150g
