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 rst makes working easier.
The connection pipe is specialized for R410A.
Forced fastening without careful centering may

Ensure that on 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 50 g/m(0.045 oz/inch).But the charge of refrigerant must
be conducted by professional air conditioner servicer. Before adding additional
perform air purging from the refrigerant pipes and indoor unit using a vacuum
refrigerant, pump,then 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 gure. (Note:
Only for heat pump unit.)

Purging Method:To use vacuum pump
1.
Detach the service port's cap of
3-way valve, the valve rod's cap for 2-way valve
and 3-way's, connect the service port into the projection of charge hose (Iow)
for gaugemanifold. Then connect the projection of charge hose (center) for gau-
gemanifold into vacuum pump.
2. gaugemanifold, operate vacuum pump. If the scale-

Vacuum for over 30min. Pull vacuum to 600 microns.
3.
After the completion of system vacuuming process, then close the
handle 'Lo' in gaugemanifold and stop the operation of the vacuum pump. Check
condition of the scale and hold it for 5-10min. If the scale-moves back in spite of
tightening, make aring work again, the return to the beginning of 3 .
4.
Open the valve rod for the 2-way valve counterclockwise to 90 degrees.
After 6 seconds, close the 2-way valve and make the inspection of gas leakage.
