Installation Procedure
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 10 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-32, 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-32 (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-32.
Once you have completed all the connections, check for
possible leaks using leak detector specifically designed
for HFC refrigerants.
