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 4.92 ft
(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. Screw the nuts to suspend the unit. Cut a pad stopper
and place it on the bracket at this time.
