6.5 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 the installation is complete in order 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, and the
unit is suspended firmly and reliably onto the hooks.
◇ 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.
