3-4 Installation

3-4-1 Selection of Installation Place

3-4-1(a) Indoor Unit

	• Install the unit at a place close to the wall facing the outside	Top view
	as it is necessary to perform piping connection with the out-
	door unit.
	- It is effective to install the unit at a window side to ensure
	uniform distribution of indoor temperature.
	• Install the unit at a place where there is no obstacle against	Above 50cm
	the wind around the air inlet and air outlet.
	• Install the unit horizontally at a stable, rigid place.
	(When installing the unit at a place subjected to vibration,
	noise may occur.)	Side view
	• Avoid a place near the door which is frequented by people.
	• Avoid a place subject to direct sunlight.	Above 20cm
	3-4-1(b) Outdoor Unit

•Place free from the risk of combustible gas leakage.

•Place which can bear the weight of the unit.

•Place which can bear the fixing strength of the outdoor unit.

•Avoid a place subject to oil (including machine oil).

•Avoid a saline place.

•Avoid a place subject to sulfide gas (hot spring zone). (When installing the unit at such special environmental conditions, it may cause machine trouble. When it is

unavoidable to use such places. It requires special maintenance.)

• A place where the discharge air and noise of the outdoor unit do not disturb the neighborhood. (Take special care not to cause any inconvenience to your neighbors when installing the unit on the borderline with your neighborhood.)

•A place where strong wind does not head against the air outlet of the outdoor unit.

(If a strong wind heads directly against the air outlet at the time of cool operation, a safety device can be operated.)

•Do not install the outdoor unit at an unstable place such as outer wall of an apartment or building.

The outdoor unit may fall down, causing severe personal or property damage or loss.

*If there is any unavoidable reason to install the unit at such a place, take the following measures against the wind;

1.When installing the unit at a roadside concentrated with buildings, install it parallel with the road.

2.Install the unit so that the air outlet faces toward the wall at a place such as rooftop, which may be subjected to strong wind.

Operating instructions and Installation

3-4-2 Electrical Work

The electrical work should be performed by a specialist qualified for the work.

•Use the three phase power supply, and be sure to install the sub power distributing board for exclusive use with the unit(separately purchased by the user).

*Avoid octopus-type wiring as it can cause a drop in voltage, thus resulting in poor performance of the automatic control circuit.

•Be sure to install circuit breaker (separately purchased by the user).

•Be sure to connect the grounding wire.

	Ampere of breaker				50 A
	Knife switch		Switch		25 A
			Fuse		25 A
	Size of grounding		wire		2.5 mm2
	Min. size of electric wires from/to				0.75 mm2
	the indoor/outdoor unit
	CAUTION

•Be sure to use the wires, and switches or fuses of power distribution board are qualified and fulfill the specification.

•Be sure to install knife switch or circuit breaker on the power distribution board.

•The electrical and grounding work should be performed as per “ technical specification of electrical facilities ” and “ specification of internal wiring ”.

• Be sure to connect main electrical input wires with	Applicable voltage 380V	342V ~ 418V
bolted connectors using compressed terminal.

When connecting 3Phase 4wires 380V AC

1.Remove cover of electric box on side panel of outdoor unit.

2.Connect electric input wires (R,S,T,N) to each terminal (R,S,T,N) of the electric box on outdoor unit respectively.

3.Connect electric wires to each terminal on indoor and outdoor unit respectively.
