2.2 Mount the unit
• Use the Φ10 lifting bolts (four).
• Removing the ceiling: Since the building structure is different, discuss building details with the interior
decoration workers.
a. Ceiling treatment: Reinforce the ceiling pedestal to make sure that the ceiling is level and to prevent ceiling
vibrations.
b. Cut off and dismantle the ceiling pedestal.
c. Reinforce the remaining surface after the ceiling is removed. Add further reinforcements to the pedestal on
two ends of the ceiling.
d. Once the main unit has been lifted 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 lift and mount the unit.
To match the existing structure, set the screw pitch according to the product dimensions shown below.

2.3 Lifting the IDU
