before drilling the holes check the dimensions between the
markings.
2) Insert bolt anchors, use existing ceiling supports or construct
a suitable support as shown in figure.

Ensure that the ceiling is strong enough to support
the weight of the indoor unit. Before hanging the unit,
test the strength of each attached suspension bolt.
If the length of suspension bolt is more than 5ft.,
support the unit to prevent vibration.
3) Install the suspension bolts depending on the ceiling type.
4) Screw eight nuts to the suspension bolts making space for
inserting the indoor unit bracket.

You must install four suspension bolts when installing
the indoor unit.

place it on the bracket at this time.
