Installation Procedure
• Torque the flare connections to the values shown in the
table.
Outer diameter (mm) Torgue(N•m)
Ø6.35 14 to 18
Ø9.52 34 to 42
Ø12.70 49 to 61
Ø15.88 68 to 82
Ø19.05 100 to 120
• 1 N·m = 10 kgf·cm
4 Connect the charging hose of low pressure side of
manifold gauge to the packed valve having a service port
as shown at the figure.
CAUTION
• The designs and shape are subject to change according to
the model.
5 Open the valve of the low pressure side(A) of manifold
gauge anticlockwise.

6 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 1 hour. 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.
7 Open the stop valve of both liquid and gas sides.
8 Mount the valve stem nuts and the service port cap to the
valve, and tighten them at the torque of
183kgf•cm with a torque wrench.
9 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 4.3 MPa and for a burst
pressure of at least 17.0 MPa. 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”.
