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 as it is necessary to perform piping connection with the out-

Top view

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 the wind around the air inlet and air outlet.

Above 50cm

• Install the unit horizontally at a stable, rigid place. (When installing the unit at a place subjected to vibration,

noise may occur. )

• Avoid a place near the door which is frequented by people.

• Avoid a place subject to direct sunlight.

Side view

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 re q u i res special m a i n t e n a n c e . )

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

the borderline with your neighborh o o d . )

• 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.

Above 100cm

* 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 ro a d .

Wall

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

* The outdoor unit should be installed in accordance with the service space.

* Avoid octopus-type wiring as it can cause a drop in voltage, thus resulting in poor performance

of the automatic control circ u i t .

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

• Be sure to connect the grounding wire .
