Install according to
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 charged, according to 20 g/m (0.018 oz/inch). But the charge of refrigerant must
be conducted by professional air conditioner servicer. Before adding additional
refrigerant, perform air purging from the refrigerant pipes and indoor unit using
a vacuum pump,then charge additional refrigerant.
