• Where there is sufficient strength to withstand the mass
of the indoor unit (if the strength is insufficient, the indoor
unit may vibrate and get in contact with the ceiling and
generate unpleasant chattering noise).
• Where a space sufficient for installation and service can
be ensured. (Refer to Fig. 1 and Fig. 2)
• Where the piping length between the indoor and the out-
door units is ensured within the allowable length. (Refer
to the installation manual attached to the outdoor unit.)
• Where there is no risk of flammable gas leak.
To determine the minimum floor area
(only for R32 refrigerant)
• Use the graph or table to determine the minimum floor area.
See figure 1 on the inside of the front cover.

• If there is extra space required for * part, servicing can be
conducted more easily if 200mm or more is secured.Install
the indoor and outdoor units, power supply wiring, remote
controller wiring and transmission wiring at least 1 meter
away from televisions or radios to prevent image interference
or noise.
(Depending on the radio waves, a distance of 1 meter may
not be sufficient to eliminate the noise.)
• Install the indoor unit as far as possible from fluorescent
lamps.
If a wireless remote controller kit is installed, the transmission
distance may be shorter in a room where an electronic light-
ing type (inverter or rapid start type) fluorescent lamp is
installed.
• The sound pressure level is less than 70 dBA.
(2) Use hanging bolts for installation.
Investigate if the installation place can withstand the mass
of the indoor unit and, if necessary, hang the indoor unit
with bolts after it is reinforced by beams etc. (Refer to the
installation pattern paper for the mounting pitch.).
(3) Ceiling height
This indoor unit can be installed up to 4.3m for 100~140
class and up to 3.5m for 35~71 class.
• Please do not take out the product giving a lot of care to the
resin side panel and discharge horizontal blade and the air
outlet.
• Please do not lift the product and do not pull it with the rein-
forced plate (right and left). When the reinforced plate bends,
it might cause noise.
