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
⑧
of the
collect gas pipe.

The allowed maximum design length of connecting pipe of
air-conditioning unit is 25m (15m for 50 Series0
。
In case the
pipe is longer than 10m, add the following amount of
refrigerant for each extra meter :
GE AIR C18 Add 30g
GE AIR C24 Add 40g
GE AIR C34 Add 40g
GE AIR C41 Add 50g
