Make the ceiling opening needed for installation where
applicable. (For existing ceilings. )
- 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). Refer to each piping or wiring
section.
- After making an opening in the ce由ng, 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 installation hooks. (Use either a MS or M10
size bolt. )
Use expansible hooks, sunken anchors, or other field supplied
parts to reinforce the ce仆ing in order to bear the weight of the
unit. Adjust clearance from the ceiling before proceeding further.
