2-4 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

〈Hold the hanging brackets in the case of moving the
indoor and outdoor units at the time of and after opening
the packages. Do not impose undue force on other parts,
such as the refrigerant piping, drain piping, or flanges,
in particular.〉
〈Add heat insulation material to the indoor unit if the
temperature above the ceiling is likely to exceed 30°C and
a relative humidity of 80%.〉
〈 Make sure that the insulation material is made of glass wool
or polyethylene foam, has a minimum thickness of 10 mm,
and can be accommodated in the opening on the ceiling. 〉
(1) Select an installation site where the following conditions are
fulfilled and that meets with your customer's approval.
• A place where cool (warm) air is delivered to the entire
room.
• 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
abd 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. 2-1)
• Where piping between indoor and outdoor units is
possible within the allowable limit. (Refer to the
installation manual of 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.)
• In the case of the installation of a wireless remote controller,
the transmission distance of the wireless remote controller
may be shortened if the room has a fluorescent light of
electronic lighting type (i.e., an inverter or rapid-start
fluorescent light). Keep the distance between the receiver
and the fluorescent light as far as possible.
