Ceiling opening and installation of hanging bolts
• Evaluate and determine the piping and wiring requirements inside the ceiling prior to the hanging of the unit.
• After installation place of the indoor unit has been determined, create opening in ceiling and install the hanging
bolts.
• For the ceiling opening size and pitch for hanging bolts refer to the dimensional drawing and the supplied
installation pattern.
• Once the ceiling void has been created, ensure that the drain pipe, refrigerant pipes, inter-connecting wires and all
control wires are in place prior to installing the actual indoor unit.
Please procure the hanging bolts and nuts for installation of the indoor unit at local site.

Treatment of ceiling
The ceiling differs according to the structure of the building. For details, consult your architect.
In the process after the ceiling panels have been removed, it is important to reinforce the ceiling construction and
ensure the ceiling remains in a horizontal position. This is to prevent possible vibration of the ceiling panels.
1. Cut and remove the ceiling material.
2. Reinforce the cut surface of the ceiling construction and add support for fixing the end of ceiling panel.
Installation of hanging bolt
Use M10 hanging bolts (4 off, locally procured).
When mounting the unit, set the pitch of the hanging bolts according to the size of the unit as detailed on the
dimensional drawing.

the indoor unit in order to hang the unit.
• Using a spirit level, check that all four sides are horizontal.
(Horizontal positioned within 5 mm)
• Cut off the installation gauge from the installation pattern.
• Using the installation gauge check and adjust clearance between the
indoor unit and the ceiling opening (1) (10 to 42 mm on each side).
Ensure that the unit is level to the ceiling and within a distance of (2)
23 mm to 28 mm below.
The installation gauge has details of how to use printed on it.
