Connection of pipes
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 first makes working easier.
The connection pipe is specialized for R410A.
Half union
Spanner
Be careful that matters, such as wastes of sands,water, etc. shall not enter the pipe.
CAUTION
The standard pipe length is C m. 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
additional refrigerant.
