REQUIREMENT
Before installation of the indoor unit be sure to remove the transportation cushion found between the fan and the bell mouth.
Running the unit without removing the cushion may damage the fan motor.
Installation of ceiling panel (Sold separately)
Install the ceiling panel after completion of the installation of the indoor unit, including all piping and wiring.
Install the ceiling panel as per the supplied Installation Manual.
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.
Be sure to remove the cushion for transportation between the fan and the bell mouth.
Check the installation dimensions of the indoor unit and the ceiling opening are correct and then install.
REQUIREMENT
Ensure the ceiling panel is mated to the ceiling surface or the indoor unit.
If the panel and unit are not mated together this may result in the formation of dew condensation causing a possible water leak.
First remove the 4 corner caps from the ceiling panel and fit to the indoor unit.
