Installation Procedure
Outer diameter (mm)
Tightening torque
Body cap (N•m) Charging port cap (N•m)
ø 6.35 20 to 25
10 to 12
ø 9.52 20 to 25
ø 12.70 25 to 30
ø 15.88 30 to 35
Over ø 19.05 35 to 40
(1 N•m = 10 kgf•cm)
NOTE
• Be extra cautious for the gas leakage from the 3-way
valve’s stem nuts (gas side), and from the service port
cap.
Pressure table for each temperature
If extra refrigerant charging is required due to gas leakage or
product relocation, see the following table.

NOTE
• Pressure for each temperature was measured at the
gas side service valve.
Step 16 Fixing and insulating the
connection part for refrigerant pipes
CAUTION
• Before wrapping the connection part for refrigerant
pipes, be sure to check whether there is gas leakage on
the connection part.
1 Wrap the foam insulation around the connection
part as shown in the figure. This wrapping minimises
condensation.
