(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 M8 or M 10 bolts for hanging the indoor unit.
Use a hole-in anchor for existing ceilings, and
a sunken insert, sunken anchor or other field
supplied parts for new ceilings to reinforce
the ceiling to bear the weight of the unit.
Adjust clearance (50 - 100 mm) from the
ceiling before proceeding further.
