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 (part #11) to wrap joint between gas pipe and the insulation (part #8).
The enclosure of the appliance shall be marked by word, or by symbols, with the direction of the fluid flow.
