Installation Procedure
CAUTION
• The designs and shape are subject to change according to
the model.
4 Open the valve of the low pressure side(A) of manifold
gauge anticlockwise.

5 Purge the air from the system using vacuum pump for
about 10 minutes.
• Close the valve of the low pressure side of manifold
gauge clockwise.
• Make sure that pressure gauge shows -0.1 MPa
(-76 cmHg) after about 10 minutes. This procedure
is very important to avoid a gas leak.
• Turn off the vacuum pump.
• Remove the hose of the low pressure side of
manifold gauge.
6 Open the stop valve of both liquid and gas sides.
7 Mount the valve stem nuts and the service port cap to the
valve, and tighten them at the torque of
18 N·m with a torque wrench.
8 Check for gas leakage.
• At this time, especially check for gas leakage from
the 3-way valve’s stem nuts(A port), and from the
service port cap.
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 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 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-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.
