Ceiling preparation: The actual procedure differs according
to the structure. Consult your builder or whoever was
responsible for the interior of the house/building.
Removal of part of the ceiling plate:
(1) In order to ensure that the ceiling is kept perfectly
horizontal and to prevent the ceiling from vibrating, the
ceiling framework must be reinforced.
(2) Cut and remove part of the ceiling framework.
(3) Reinforce the ends of the ceiling framework where it was
cut and add framework to secure the ends.
G
Some piping and wiring connections must be made in the
ceiling after the unit has been suspended. After selecting where
the unit will be installed, decide on the direction of the piping
connection. If the ceiling is already installed, prepare the
refrigerant pipes, drain pipe, indoor to outdoor unit connection
wiring and the remote control cord at the piping and wiring
connection positions before suspending the indoor unit.

Hanging Unit
(1) Raise the unit by using a
lifting device, then secure
the hangers to the hanging
bolts. Be sure to fix the nuts
onto both the upper and
under side of the hanger
and the washer (under side
only);
(2) Install the unit horizontally
by using a level. Failure to
do this will cause water
leakages.
