A: Service port

For vacuuming in the refrigerant pipes on the site. (Tightening torque 12 N·m)

B: Shaft

Fully closed at the factory, when connecting the piping, and when vacuuming. Open fully after these operations are completed. <When opening>

• Turn the shaft counterclockwise with a hexagonal wrench.

• Turn around the shaft until it stops. <When closing>

• Turn the shaft clockwise with a hexagonal wrench.

• Turn around the shaft until it stops.

C: Flare nut

Coat the flare contact surface with refrigerating machine oil (small amount of ester oil, ether oil, or alkyl benzene) and tighten the nut with a double-ended wrench (refer to the following table for tightening torque).

D: Cap

Remove the cap before operating the shaft. Be sure to return it to the original position after completing the operation.

E:Packing

Coat both sides of the packing with machine refrigerating oil (small amount of ester oil, ether oil, or alkyl benzene) and tighten the flange. (Tightening torque 25 N·m)
