3. Indoor Unit Installation

Make sure that only specified components are used for the installation works.
3.1 Installation with lifting bolts
Make sure the ceiling is at a level position in the vicinity where the ceiling will
be dismantled. Strengthen the ceiling beam to prevent the vibrations of the
ceiling. Cut the beam of the ceiling. Strengthen the part of ceiling where the cut
is, and reinforce the ceiling beam. Once the main unit has been hoisted and
mounted, carry out the piping and wiring works within the ceiling. Determine the
outlet direction of the piping after the installation site has been finalized. For a
site where the ceiling is already available, first connect and put in position the
refrigerant piping, water discharge piping, connecting wires of the indoor unit,
and wired controller before you hoist and mount the unit.
Use different bolts for the installation depending on the installation environment.
Wooden structure
Secure the square rod on the beam to set
the hoisting bolts.
Original concrete slab structure
Use embedded bolts, and pull bolts.

Caution
• All bolts should be made from high quality carbon steel (with galvanized
surface or other rust prevention treatment) or stainless steel.
• How the ceiling should be handled will differ with the type of building. For
specific measures, please consult the building and renovation engineers.
• How the lifting bolt should be secured depends on the specific situation,
and it must be secure and reliable.
