2. Install the unit by hoist hook and check out whether ceiling is strong enough to hold the unit. In case of
insufficient strength, reinforce ceiling prior to installation.

All above parts shall be procured in local region.
Preparation Prior to Installation
1. Decide on the relative positions of the unit and hoist hook. (Refer to installation diagram)
Set aside service space, including service port (open a service port beside electrical cabinet on the ceiling to
facilitate checking and maintaining of air screen, heat exchange device and fan).
2. Make sure that External Static Pressure does not exceed range limits.
3. Opening installing port: put signal transmission line and wire control cable through the line hole on the unit after
opening installing port on the ceiling.
4. Keep ceiling in level position after opening installing port; reinforce
ceiling when necessary to prevent vibration.
(Concerned architect or carpenter can be consulted).
5. Installing Draw Bolt (Choose from the M10-M12 Range)
Installation Position
■ Please install in places capable of bearing unit weight. Improper installation is dangerous; it not only causes
vibration but produces operating noises.
■ Set aside service space and access hole. Please make sure that access hole is preset to check air screen, heat
exchange device and fan.
■ Do not install the unit directly on roof or wall; otherwise, the unit may directly touch roof or vibration will ensue.
