(4) Open installation holes
(in the case of installation onto the existing ceiling).
• Open the installation holes on the ceiling of the
installation location, and work on the refrigerant piping,
drain piping, remote controller wiring (unless a wireless
remote controller is used), and wiring between the indoor
and outdoor units to the piping connection port and
wiring connection port of the indoor unit (refer to each
piping and wiring procedure items).
• Ceiling framework reinforcement may be required in
order to keep the ceiling horizontal and prevent ceiling
vibration after opening the ceiling holes. For details,
consult your building and upholstery work contractors.
(5) Install the hanging bolts.
• Use M10 bolts for hanging the indoor unit.
Use hole-in-anchors for the existing bolts and embedded
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 (50 -100 mm) from the
ceiling in advance.
