Connection of pipes
To bend a pi
pe, 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

Forced fastening without careful centering may
damage the threads and cause a leakage of gas.

CAUTION
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 profes
sional air conditioner engineer. Before adding additional refrigerant,
