Place the pattern sheet on the ceiling at the spot where you want to
install the indoor unit.

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 1.5m, it is
required to prevent vibration.
