In order to ensure that the ceiling is kept perfectly
horizontal and to prevent the ceiling from vibrating the
ceiling framework must be reinforced;

(3) Reinforce the ends of the ceiling framework where it was
cut and add framework to secure the ends.

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.
