2. Referring to the illustration opposite, tighten the are nut on section B rst
manually and then with a torque wrench, applying the following torque.
Outer Diameter (D) Torque (N•m)
ø6.35 mm(1/4") 14~18
ø9.52 mm(3/8") 34~42
ø12.70 mm(1/2") 49~61
ø15.88 mm(5/8") 68~82
ø19.05 mm(3/4") 100~120
3. Connect the charging hose of low pressure side of manifold gauge to the
packed valve having a service port as shown at the gure.
• Make the electrical connection and leave the system into “stand by
mode”. Do not turn on the system.
• This is necessary to speed up vacuum operation (full OPEN
position of Electronic Expansion Valve - EEV -).
CAUTION
4. Open the valve of the low pressure side(A) of manifold gauge
counterclockwise.

The designs and shape are subject to
change according to the model.
5. Purge the air from the system using vacuum pump for about 10minutes.
Close the valve of the low pressure side of manifold gauge clockwise.
Make sure that pressure gauge shows -0.1MPa(-76cmHg) after about
10minutes. This procedure is very important to avoid a gas leak.
Turn o the vacuum pump.
Remove the hose of the low pressure side of manifold gauge.
6. Set valve cork of both liquid side and gas side of packed valve to the open
position.
7. Mount the valve stem nuts and the service port cap to the valve, and tighten

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.
• Connect the indoor and outdoor units using pipes with ared 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 4200kPa and for a burst pressure of at least 20700kPa. Copper pipe
for hydro-sanitary applications is completely unsuitable.
• For sizing and limits (height dierence, line length, max. bends, refrigerant charge, etc.) see “Connecting
refrigerant pipe section”.
