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.
• 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.

ing the indoor unit.
• You must install all the suspension rods.
