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

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.

Purging Method:To use vacuum pump
1.
Remove the service port cap of the 3-way valve and the valve stem cap for both
valves. Connect the low pressure hose from the manifold set to the 3-way valve.
Connect the center hose to the vacuum pump.
2.
Open the handle on low side of manifold and
side gauge reaches a vacuum immediately, ensure the hoses are connected
properly and the low side manifold handle is open.
3.
Vacuum for a minimum of 15 minutes and check the gauge for a proper vacuum.
After the completion of vacuuming, close the handle 'Lo' in gaugemanifold and
stop the operation of the vacuum pump.
the vacuum level again in 1-2 minutes. If you lose the vacuum, ensure all
connections are tight and flare the tubes again if needed.
4.
Open the valve rod stem the 2-way valve counterclockwise to 90 degrees.
After 6 seconds, close the 2-way valve and inspect for gas leakage.
