Ceiling preparation: The actual procedure differs according
to the structure. Consult your builder or whoever was
responsible for the interior of the house/building.
(1) Removal of part of the ceiling plate:
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 pipe, 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.
