Indoor unit installation
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.
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 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
Concrete
Insert
Hole in anchor

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.
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 installing the indoor unit, make sure it is not tilted
toward front or back side.
24 English

Purging the unit
From factory the unit is supplied and set with a pre-charge of nitrogen gas. (insert gas) Therefore, all insert gas must be
purged before connecting the assembly piping.
Unscrew the pinch pipe at the end of each refrigerant pipe.
Liquid refrigerant port
Gas refrigerant port
NOTE
ENGLISH
RESULT : All inert gas escapes from the indoor unit.
•To prevent dirt or foreign objects from getting into the pipes during
installation, do NOT remove the pinch pipe completely until you are
ready to connect the piping.
CAUTION
•Connect the indoor and outdoor units using pipes with flared
connections(not supplied). For the lines, use insulated,
unwelded, degreased and deoxidized copper pipe (Cu DHP
type to ISO 1337 or UNI EN 12735-1), suitable for operating
pressures of at least 4200kPa and for a burst pressure of at
least 20700kPa. Copper pipe for hydro-sanitary applications
is completely unsuitable.
•For sizing and limits (height difference, line length, max.
bends, refrigerant charge, etc.) see the outdoor unit
installation manual.
• All refrigerant connection must be accessible, in order to
permit either unit maintenance or removing it completely.
 The designs and shape are subject
to change according to the model.
English 25
Connecting the refrigerant pipe
There are two refrigerant pipes of different diameters :
◆ A smaller one for the liquid refrigerant
◆ A larger one for the gas refrigerant
◆ The inside of copper pipe must be clean & has no dust
1. Remove the pinch pipe on the pipes and connect the assembly pipes to each pipe, tightening the nuts, first
manually and then with a torque wrench, a spanner applying the following torque.

NOTE
•If the pipes must be shortened refer to page 27.
2. Must use insulator which is thick enough to cover the refrigerant tube to protect the condensate water on the
outside of pipe falling onto the floor and the efficiency of the unit will be better.
3. Cut off any excess foam insulation.
4. Be sure that there must be no crack or wave on the bended area.
5. It would be necessary to double the insulation thickness(10mm or more) to prevent condensation even on the
insulator when if the installed area is warm and humid.
6. Do not use joints or extensions for the pipes that connect the indoor and outdoor unit. The only permitted
connections are those for which the units are designed.

Cutting/Flaring the pipes
1. Make sure that you have the required tools available. (pipe cutter, reamer, flaring tool and pipe holder)
2. If you wish to shorten the pipes, cut it with a pipe cutter, taking care to ensure that the cut edge remains at a 90°
angle with the side of the pipe. Refer to the illustrations below for examples of edges cut correctly and incorrectly.

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 responsable of installer to pressurize the
whole system with nitrogen (using a cylinder with pressure reducer) at a
pressure above 2 bar, less than 40 bar (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.
CAUTION
•Discharge all the nitrogen to create a vacuum and charge
the system.
 The designs and shape are subject to
change according to the model.
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 Acrylonitrile Butadien Rubber
separately around each refrigerant pipe.
No gap
NOTE
•Always make the seam of pipes face upwards.
2 Wind insulating tape around the pipes and drain hose avoiding to
compress the insulation too much.
3 Finish wrapping insulating tape around the rest of the pipes leading to the outdoor
unit.
4 The pipes and electrical cables connecting the indoor unit with the
outdoor unit must be fixed to the wall with suitable ducts.
