Connection of Refrigerant Pipe
When connecting the pipe to the unit or disassemble the pipe from the unit, use the spanner and the torque
spanner at the same time as shown in the figure.
Refer to Table 1 for the torque needed for tightening the conical nut.
Apply refrigerant oil in and outside the conical nut during the connection. First manually screw 3 to 4 circles, and
then use the torque spanner to tighten it.
Refer to table 1 to decide the tightening torque (excess tightening may damage the nut so as to cause leakage).
Check if the connecting pipe has leakage, and then carry out thermal insulation as shown in the figure.
Only use middle sponge (11) to wrap the joint part between the gas pipe and the insulating sleeve
collect gas pipe.

30~40N.m
The allowed maximum design length of connecting pipe of
air-conditioning unit is 25m (15m for 50 Series0 In case the
40~50N.m
pipe is longer than 10m, add the following amount of
refrigerant for each extra meter :
60~65N.m
GE AIR C18
GE AIR C24
70~75N.m
GE AIR C34
