4 Install the suspension bolts, depending on the ceiling
type.
CAUTION
Make sure 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 the suspension bolt is more than 1.5 m,
you are required to prevent vibration.
5 Screw eight pairs of nuts and washers to the
suspension bolts, making space for hanging the indoor
unit.
CAUTION
You must install all of the suspension rods.
It is important to leave sufficient space in the false
ceiling to allow access for maintenance or repairs to
the drainage pipe connection, the refrigerant pipe
connection, or to remove the unit if necessary.
6 Hang the indoor unit to the suspension bolts between
two nuts. Cut a pad stopper and place it on the
suspension bolts to hold the washers. Remove the
stopper and screw the nuts to fix the unit.
