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

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
charge additional refrigerant.

Connection
Take off the panel(top), by removing the 5 screws.
Remove the plugs on the conduit plate.
Temporarily mount the conduit tubes on the conduit plate.
Connect both the power supply and unit wire harness to
the corresponding terminals on the terminal board.
Ground the unit in accordance with local codes.
Allow several extra inches of wire for making wiring
connections.
Use lock nuts to secure conduit tubes.
Attaching Drain-Elbow
If the drain-elbow is used,
please attach it as figure. (Note:
Only for heat pump unit.)
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.
