To bend a pipe, give the roundness as large as possible not to crush the pipe ,
and the bending radius should be 30 to 40 mm or longer.
Connecting the pipe of gas side rst makes working easier.
The connection pipe is specialized for R32.
Half union
Flare nut
Torque wrench
CAUTION
Be careful that matters, such as wastes of sands,water,, etc. shall not enter the pipe.
The standard pipe length is Cm. If it is over D m, the function of the unit will be affected. If the pipe has
to be lengthened, the refrigerant should be charged, according to E g/m. But the charge of refrigerant
must be conducted by professional air conditioner engineer. Before adding additional refrigerant,
perform air purging from the refrigerant pipes and indoor unit using a vacuum pump,then
Spanner
Forced fastening without careful centering may
damage the threads and cause a leakage of gas.
