Connection of pipes
To bend a pipe, be careful not to crush the pipe,
and the bending radius should be 30 (1 1/6) to 40 mm (1 4/7) or longer.
Connecting the pipe of gas side first makes working easier.
The connection pipe is specialized for R410A.
Forced fastening without careful centering may
damage the threads and cause a leakage of gas.

Ensure that no dirt or debris enters the pipe.
The standard pipe length is 7m (27 9/16) . If it is over 7m (27 9/16) , the function
of the unit will be affected. If the pipe has to be lengthened, the refrigerant should

be conducted by professional air conditioner servicer. Before adding additional
refrigerant, perform air purging from the refrigerant pipes and indoor unit using
