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.

Hole in plug
Suspension bolt (M8) - field supply
3 Install the suspension bolts depending on the ceiling type.
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 4.92 ft ( 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.
Pad stopper
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 0.118 inch ( 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 back side.
CAUTION
• Noise will increase 3~6 dB(A) when the air flow enters from
the bottom side (Only for AC***BNLDCH indoor unit product).
