Installation Procedure
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 0.2MPa, 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.

according to the model.
Step 10 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 25.

1 Open the liquid stop valve and gas stop valve.
2 Operate the air conditioner by pressing the K2 button
on the outdoor unit PCB.
3 After about 30 minutes, charge the refrigerant
through the service port of the gas stop valve.

2 Charge the refrigerant through the service port of the
liquid stop valve.
NOTE
• Do not charge the refrigerant through the service port
of the gas stop valve.
