Installation Manual
- 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 control
 (unnecessary for wireless type). Refer to each piping or wiring 
 section.
- 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.
Use expansible hooks, sunken anchors or other field supplied 
parts to reinforce the ceiling in order to bear the weight of the 
unit. Adjust clearance from the ceiling before proceeding further.
Installation example see figure below.
2) Make the ceiling opening needed for installation where 
 applicable.(For existing ceilings.)
3) Install the installation hooks. (Use either a M8 or M10 
 size bolt. )
1 Ceiling slab
2 Expansible hook (optional)
3 Installation hook (optional)
4 False ceiling 
For other installation than standard installation,
contact your dealer for details.
NOTE

Installation is possible with a ceiling dimension of 23.6in 
/ 600 mm (marked with * ) . However, to achieve a 
ceiling-panel overlapping dimension of 0.6in / 15 mm, the 
spacing between the ceiling and the unit should be 0.8in 
/ 20 mm or less. If the spacing between ceiling and the unit 
is over 0.8in / 20 mm , attach sealing material in the part 
or recover the ceiling.
