Step 4 Installing the indoor unit
When deciding on the location of the air conditioner the
following restrictions must be taken into account.
1
Place the pattern sheet on the ceiling at the spot
where you want to install the indoor unit.
NOTE
• Since the diagram is made of paper, it may shrink
or stretch slightly due to temperature or humidity.
For this reason, before drilling the holes, be sure
to maintain the correct dimensions between the
markings.
2
Insert bolt anchors, use existing ceiling supports or
construct a suitable support as shown in figure.

Suspension bolt (M8) - field supply
Hole in anchor
Hole in plug
Insert
3
Install the suspension bolts, depending on the ceiling
type.
Ceiling support
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.
4
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.
5
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 washer. Remove the
stopper and screw the nuts to fix the unit.

Check the level of the indoor unit by using a leveler.
• A tilt of the indoor unit may cause malfunction of a
built-in float switch and water leaks.
