drain piping and wiring for remote controller (unnecessary for
wireless type) and indoor-outdoor unit casing outlet. 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.
3.
Install the suspension bolts. (use either a W3/8 or M10 size
bolt.)
Use anchors for existing ceilings, and a sunken insert, sunken
anchors or other field supplied parts for new ceilings to reinforce the
ceiling in order to bear the weight of the unit. Adjust clearance from
the ceiling before proceeding further.
