䡵 Installation is possible when ceiling opening dimensions is as follows
• When installing the unit within the frame for fixing false ceiling.
NOTE
• Installation is possible with a ceiling dimension of 35-7/8in. (marked with *). However, to achieve a ceiling-
panel overlapping dimension of 13/16in., the spacing between the ceiling and the unit should be 1-3/8in. or
less. If the spacing between ceiling and the unit is over 1-3/8in., 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 indoor-outdoor unit casing outlet. Refer to “6. REFRIGERANT PIPING WORK”, “7. DRAIN
PIPING WORK” and “8. ELECTRIC WIRING WORK”.
• 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 for details.
(3) Install the suspension bolts.
(Use either a M8~M10 size bolt or the equivalent)
Use a hole-in anchor for existing ceilings, and a
sunken insert, sunken anchor or other field sup-
plied parts for new ceilings to reinforce the ceiling
to bear the weight of the unit. Adjust clearance
(2-4in.) from the ceiling before proceeding
further.
NOTE
• All the above parts are field supplied.
