NOTE TO THE 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
(1) Select an installation site where the following condi-
tions are fulfilled and that meets your customer’s
approval.
• In the upper space 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 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.
(Refer to Fig. 1)
If sufficient clearance could be ensured at*, leave a
space of 200 mm or more between the unit and it’s sur-
roundings easier maintenance and service.
• Where piping between indoor and outdoor units is possi-
ble within the allowable limit. (Refer to the installation
manual for the outdoor unit.)
CAUTION
• Install the indoor and outdoor units, power supply wiring and
connecting wires at least 1 meter away from televisions or
radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter may
not be sufficient enough to eliminate the noise.)
(2) This indoor unit may be installed on ceilings up to 3.5 m
in height. However, if the ceiling is higher than 2.7m,
the remote control will have to be set locally. (Refer to
“11. FIELD SETTING” on page 12)
(3) Use suspension bolts for installation. Check whether
the ceiling is strong enough to support the weight of
the unit or not. If there is a risk, reinforce the ceiling
before installing the unit.
(Installation pitch is marked on the paper pattern for instal-
lation. Refer to it to check for points requiring reinforcing.)

Are wiring and piping cor-
rect?
The unit may malfunction or
the components burn out.
Is the unit safely grounded?
Dangerous at electric leak-
age.

Is something blocking the air
outlet or inlet of either the
indoor or outdoor units?
It may result in insufficient
cooling.
Are refrigerant piping length
and additional refrigerant
charge noted down?
