Installation Procedures
(3) If necessary, make a hole for installation and inspection on the ceiling. (used for the situation
with a ceiling)
For the size of the inspection hole on the ceiling, please refer to the above drawing.
Before installation, finish all the preparations for all piping connected to indoor units (refrigerant,
water drainage) and wiring (connection line of the line control, connection line between indoor
units and outdoor unit) so that they can be connected with indoor units right 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.
(4) Install the hoisting studs (M10 bolts)
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.
(5) Installation of Indoor Units
Fix the indoor unit with the hoisting stud.
If necessary, the machine can be hanged
on the beam with bolts instead of the
hoisting stud.
NB:
When the sizes of the main unit don't match the hole on the ceiling, regulate the slot on the hanging
bracket.
