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 unitunder 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.
