Installation Procedure
Installing the indoor unit
When deciding on the location of the air conditioner with
the owner, 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 maintain the
correct dimensions between the markings.
2 Insert bolt anchors. Use existing ceiling supports or
construct a suitable support as shown in figure.
Concrete
Suspension bolt (M8) - field supply
Insert
Hole in anchor
Hole in plug
3 Install the suspension bolts depending on the ceiling type.
Ceiling support
CAUTION
• Ensure 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 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.
4 Screw eight nuts to the suspension bolts making space for
hanging the indoor unit.
NOTE
• You must install all the suspension rods.
5 Hang the indoor unit to the suspension bolts between two
nuts.
Rubber
Hanger Bracket
CAUTION
• Piping must be laid and connected inside the ceiling
when suspending the unit. If the ceiling is already
constructed, lay the piping into position for connection
to the unit before placing the unit inside the ceiling.
6 Screw the nuts to suspend the unit.
7 Adjust level of the unit by using measurement plate for all
4 sides.
CAUTION
• For proper drainage of condensate, give a 3mm
slant to the left or right side of the unit which will be
connected with the drain hose, as shown in the figure.
Make a tilt when you wish to install the drain pump,
too.
When the drain hose is installed to the right.

• When installing the indoor unit, make sure it is not
tilted toward front or b
ack side.
