Installation Part
Indoor Unit Installation
It is recommended to install the Y-joint before installing the
indoor unit.
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.
 Pattern sheet is supplied depending on the
model type.
2.
Insert bolt anchors, use existing ceiling supports or
construct a suitable support as shown in figure.

Hole in plug
Suspension bolt(Φ9.52 or M10)
3.
Install the suspension bolts depending on the ceiling type.
 Ensure that the ceiling is strong enough to
support the weight of the indoor unit.
CAUTION
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.
You must install the suspension bolts more than
four when installing the indoor unit.
CAUTION
Rubber
5.
Hang the indoor unit to the suspension bolts between two nuts.
Note Piping must be laid and connected inside the ceiling
when suspending the unit. If the ceiling is already con-
structed, 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.
Note For proper drainage of condensate, give a
10mm(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.

Performing Leak Test & Insulation
Leak test
LEAK TEST WITH NITROGEN(before opening valves)
In order to detect basic refrigerant leaks, before recreating the
vacuum and recirculating the R410A, it's responsible of installer
to pressurize the whole system with nitrogen(using a pressure
regulator) at a pressure above 4.1MPa(gauge).
LEAK TEST WITH R410A(after opening valves)
Before opening valves, discharge all the nitrogen into the
system and create vacuum. After opening valves check leaks
using a leak detector for refrigerant R410A.

Insulation
Once you have checked that there are no leaks in the system,
you can insulate the piping and hose.
1. To avoid condensation problems, place T13.0 or thicker
Acrylonitrile Butadien Rubber separately around each
refrigerant pipe.
Note
Always make the seam of pipes face upwards.
