3.2 Indoor unit suspension
◇
Select the suspension foundation:
The suspension foundation is a structure of either wooden frame or reinforced
concrete. It must be firm and reliable to bear at least 4 times weight of itself and capable of
bearing vibration for long periods.
◇
Fixing of suspension foundation:
◇
Fix the suspension bolts either as shown in the picture or by a steel or wooden bracket.
◇
If this unit is installed on a sloping ceiling, a cushion block should be installed between
the ceiling and the air outlet panel, in order to ensure that the unit is installed on a level
surface.
This is as shown in the drawing as follows:
◇
Adjust the relative position of the suspension hook on the suspension bolt so that the
unit can be in level position in all directions. Check with a level gauge after installation to
ensure that the indoor unit is horizontal, otherwise it will cause water leakage, air leakage
etc.
◇
Tighten the bolt and ensure that four hooks are in close contact with the nuts and
washers, to fix the indoor unit under the ceiling.
◇
After the unit is installed ensure it is secure and does not shake or sway.
◇
Ensure that the centre of the indoor unit is in alignment with the centre of the opening in
the ceiling.
