[ PRECAUTION ]
If installing the wireless kit in a room with electronic fluores-
cent lighting (inverter or rapid start type), the remote con-
troller’s transmission distance may be shortened. Indoor
units should be installed as far away from fluorescent light-
ing as possible.
(2) Ceiling height
These units can be installed with ceilings up to 3 m in
height.
Install this unit where the height of bottom panel is more
than 2.5 m so that the user cannot easily touch.
(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.)
4. PREPARATIONS BEFORE INSTALLATION
(1) Relation of ceiling opening to units and suspension
bolt position
(2) Make the ceiling opening needed for installation, where
applicable.
• Refer to the paper pattern for installation for ceiling open-
ing dimension.
• Create the ceiling opening required for installation. From
the side of the opening to the casing outlet, implement
the refrigerant and drain piping and wiring for remote con-
troller (unnecessary for wireless type) and indoor-out-
door unit casing outlet. Refer to each PIPING or WIRING
section.
• After making an opening in the ceiling, it may be neces-
sary to reinforce ceiling beams to keep the ceiling level
and to prevent it from vibrating. Consult the builder for
details.
(3) Install the suspension bolts. (Use either a W3/8 or M10
size bolt.)
Use a hole-in-anchor for existing ceilings, and a sunken
insert, sunken anchor or other part to be procured in the
field for new ceilings to reinforce the ceiling to bearing the
weight of the unit. Adjust clearance from the ceiling before
proceeding further.
5. INDOOR UNIT INSTALLATION

Installing optional accessories (except for the decoration
panel) before installing the indoor unit is easier. However,
for existing ceilings, install branch duct before installing
the unit.

As for the parts to be used for installation work, be sure to use
the provided accessories and specified parts designated by our
company.
(1) Install the indoor unit temporarily.
• Attach the hanger bracket to the suspension bolt. Be sure
to fix it securely by using a nut and washer from the upper
and lower sides of the hanger bracket. The washer fixing
plate will prevent the washer from falling.
