Connection of refrigerant pipe
•
Be sure to use both a spanner and torque wrench together as shown in the drawing, connecting or
disconnecting pipes to/from the unit.
•
Refer to table 1 to determine the proper tightening torque (over tightening may damage the flare
and cause leaks.)
•
When connecting the flare nut, coat the flare both inside and outside with refrigerating machine oil
and initially tighten by hand 3 or 4 turns.
•
Check the pipe connector for gas leaks, then insulate it as shown in the drawing below.
•
Use sealing pad (11) to wrap joint between gas pipe and the insulation (8).
