•
Check the strength and level of the installation ground
so that the unit will not cause any operating vibration or
noise after installed.
• Fix the unit securely by means of the foundation bolts.
(Prepare 4 sets of 1/2” foundation bolts, nuts and wash-
ers; all separately available.)
•
It is best to screw in the foundation bolts until their ends
are 1 inch from the foundation surface.

This unit can be located at ground floor level or on flat roofs.
At ground floor level, the unit must be on a solid, level foun
-
dation that will not shift or settle. To reduce the possibility
of sound transmission, the foundation slab should not be in
contact with or be an integral part of the building foundation.
Care should be taken to ensure the unit is installed away
from noise sensitive locations such as bedrooms, windows
and outdoor living areas. Ensure the foundation is sufficient
to support the unit. A concrete slab raised above ground level
provides a suitable base.

If it is necessary to install this unit on a roof structure, ensure
the roof structure can support the weight and that proper
consideration is given to the weather-tight integrity of the roof.
Since the unit can vibrate during operation, sound vibration
transmission should be considered when installing the unit.
Vibration absorbing pads or springs can be installed between
the air conditioner unit legs or frame and the roof mounting
assembly to reduce noise vibration.
