NOTE TO INSTALLER

• Be sure to instruct customers how to properly operate the

unit (especially cleaning filters, operating different functions,
and adjusting the temperature) by having them carry out
operations themselves while looking at the manual.

3. SELECTING INSTALLATION SITE

Please attach additional thermal insulation material to the unit
body when it is believed that the relative humidity in the ceiling
exceeds 80%. Use glass wool, polyethylene foam, or similar
with a thickness of 3/8”. or more as thermal insulation material.
For this unit, you are able to select air flow direction.
To enable the discharge of air in 2 or 3 directions, it is necessary
to purchase the optional blocking pad kit.

(1) Select an installation site where the following conditions are

fulfilled and that meets with your customer’s approval.
• In the upper space (including the back of the ceiling) of the

indoor unit where there is no possible dripping of water
from the refrigerant pipe, drain pipe, water pipe, etc.

• Where optimum air distribution can be ensured.
• Where nothing blocks the air passage.
• Where condensate can be properly drained.
• If supporting structural members are not strong enough

to take the unit’s weight, the unit could fall out of place
and cause serious injury.

• Where the false ceiling is not noticeably on an incline.
• Where there is no risk of flammable gas leakage.
• Where sufficient clearance for maintenance and service

can be ensured.

• Where piping between indoor and outdoor units is possi-

ble within the allowable limit. (Refer to the installation
manual of the outdoor unit.)

NOTE

• Install the indoor and outdoor units, power supply wiring and

connecting wires at least 3.5ft. away from televisions or
radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 3.5ft. may not
be sufficient enough to eliminate the noise.)

(2) Ceiling height

This indoor unit may be installed on ceilings up to 11.5 ft.

(30, 36: 13.8 ft.) in height. (Refer to the table.)

(3) Air flow direction

(The below figures are greatly generalized.)

Select the air flow directions best suited to the room and

point of installation. (For air discharge in 2 or 3 directions, it

is necessary to make field settings by remote controller and

to close the air outlet(s). Refer to the installation manual of

the optional blocking pad kit and the section entitled “FIELD

SETTING”.)
