■ Before installation, nish all the preparations for all piping connected to indoor units (refrigerant, water drainage)
and wiring (connection line of the wired control, connection line between indoor units and outdoor unit) so that
they can be connected with indoor units after installation.
■ For the inspection hole, the ceiling might be reinforced to keep the evenness of the ceiling and avoid the vibration
of the ceiling. For details, please consult the construction contractor.
In order to support the weight of the unit, use barb bolts in the situation
with a ceiling. In the situation with the new ceiling, use inlaid bolts,
embedded bolts or other parts provided on site. Before proceeding the
installation, adjust the gap between the bolt and the ceiling.

When the sizes of the master unit don't match the hole on the ceiling, regulate the slot on the hanging bracket.
