Installation Procedure
3 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
1.5m (4.92 ft), you are required to prevent vibration.
• If this is not possible, create an opening on the false
ceiling in order to be able to use it to perform the
required operations on the indoor unit.
4 Screw eight 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.
5 Hang the indoor unit to the suspension bolts between
two nuts. Screw the nuts to suspend the unit.
