(4) 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 installation. Refer to it to check for points
requiring reinforcing.)

NOTE
• Installation is possible with a ceiling
dimension of 26in. (marked with *).
However, to achieve a ceiling-panel
overlapping dimension of 13/16in., the
spacing between the ceiling and the unit
should be 1-3/4in. or less. If the spacing
between ceiling and the unit is over
1-3/4in., attach ceiling material to
part or recover the ceiling.

(2) Make the ceiling opening needed for installation where applicable. (For existing ceilings)
• Refer to the paper pattern for installation (5) for ceiling opening dimensions.
• 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 controller (unnecessary for
wireless type) and wiring between units. Refer to each PIPING or WIRING section.
• After making an opening in the ceiling, it may be necessary to reinforce ceiling beams to keep the
ceiling level and to prevent it from vibrating. Consult the builder or engineer for details.
