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.
t Since the diagram is made of paper, it may shrink or stretch
NOTE
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 gure.
3. Install the suspension bolts depending on the ceiling type.
t Ensure that the ceiling is strong enough to support the weight
CAUTION
of the indoor unit. Before hanging the unit, test the strength of
each attached suspension bolt.
t If the length of suspension bolt is more than 1.5m (4.92 ft), it is
required to prevent vibration.
t 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.

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.
t Connect the indoor and outdoor units using pipes with ared connections(not supplied). For the lines,
CAUTION
use insulated, unwelded, degreased and deoxidized copper pipe,(Cu DHP type to ISO 1337), suitable for
operating pressures of at least 4200kPa(609.2 psi) and for a burst pressure of at least 20700kPa(3002.3 psi).
Copper pipe for hydro-sanitary applications is completely unsuitable.
t For sizing and limits (height dierence, line length, max. bends, refrigerant charge, etc.) see the outdoor
unit installation manual.
t All refrigerant connection must be accessible, in order to permit either unit maintenance or removing it
completely.

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 R-410A, it’s responsible of installer to pressurize the whole
system with nitrogen (using a pressure regulator) at a pressure above 4.1MPa
[594.7 psig (gauge)].
LEAK TEST WITH R-410A (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
R-410A.
CAUTION
Insulation
Once you have checked that there are no leaks in the system, you can insulate the piping and hose.
t Discharge all the nitrogen to create a vacuum and charge the system.
1. To avoid condensation problems, place T13.0 (1/2”) or thicker
Acrylonitrile Butadien Rubber separately around each refrigerant pipe.
t Always make the seam of pipes face upwards.
NOTE
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 xed to the wall with suitable ducts.
