CAUTION
Reduce the distance between the unit and ceiling to
1-3/8 in. (35 mm) or below in order to maintain an over-
lapping panel margin 13/16 in. (20 mm) for the opening
on the ceiling. If the distance exceeds 1-3/8 in. (35 mm),
attach ceiling material to the part marked
the ceiling. (Refer to Fig. 6)

(2) Make the ceiling opening required for installation.
• Use the installation pattern paper (5) matched to the
ceiling opening dimension.
• Make the ceiling opening required for installation at
the installation location and carry out refrigerant/drain
piping, power supply wiring, remote controller wiring
(not needed in case of wireless remote con troller) and
wiring between the indoor and outdoor units. (Refer
to each section 5. REFRIGERANT PIP ING WORK,
6. DRAIN PIPING WORK and 7. ELECTRIC WIRING
WORK)
• After making the opening, sometimes it is necessary
to reinforce the ceiling framework to maintain a level
ceiling and prevent it from vibrating.
For details, consult with the builder and interior de-
signer.
(3) Install the hanging bolts.
• Use M8 or M10 bolts for hanging the indoor unit.
• Use hole-in-anchors for the existing bolts and embed-
ded inserts or foundation bolts for new bolts, and fix the
indoor unit firmly to the building so that it may withstand
the mass of the unit.
In addition, adjust clearance (2 – 4 in. (50 – 100 mm))
from the ceiling in advance.
