Installation Procedure
12735-1), suitable for operating pressures of at least
4200 kPa and for a burst pressure of at least 20700
kPa. Copper pipe for hydro-sanitary applications is
completely unsuitable.
• For sizing and limits (height difference, line length,
max. bends, refrigerant charge, etc.) see “Connecting
refrigerant pipe section”.
Step 8 Adding refrigerant (R-410A)
The outdoor unit is loaded with sufficient refrigerant
for the standard piping. Thus, refrigerant must be added
if the piping is lengthened. This operation can only
be performed by a qualified refrigeration specialist.
To determine the quantity of refrigerant charge, see
Calculating the quantity of refrigerant to add on page
17.
1 Check if the stop valve is closed completely.
2 Charge the refrigerant through the service port of the
liquid stop valve.
3 If you have any difficulty charging the refrigerant as
described in the steps above, take the following steps:
a Open the liquid stop valve and gas stop valve.
b Operate the air conditioner by pressing the K2
key on the outdoor unit PCB.
c After about 30 minutes, charge the refrigerant
through the service port of the gas stop valve.

Calculating the quantity of refrigerant to add
The quantity of additional refrigerant is variable
according to the installation situation. Thus, make sure
the outdoor unit situation before adding refrigerant.
This operation can only be performed by a qualified
refrigeration specialist.

Step 9 Performing the gas 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 is
the responsibility of the installer to pressurize the whole
system with nitrogen (using a cylinder with pressure
reducer) at a pressure above 0.2 MPa, less than 4MPa
(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.
Once you have completed all the connections, check for
possible leaks using leak detector specifically designed
for HFC refrigerants.
