min-radius 3.9" (10cm)
6. After connecting the copper pipes to the indoor unit, wrap the power cable, signal cable and the piping together with binding tape.
NOTE: DO NOT intertwine signal cable with other wires. While bundling these items together, do not intertwine or cross the signal cable with any other wiring.

BEFORE PERFORMING ANY ELECTRICAL WORK, READ THESE REGULATIONS

Make sure that you do not cross your electrical wiring with your signal wiring. This may cause distortion and interference. No other equipment should be connected to the same power circuit. Connect the outdoor wires before connecting the indoor wires.

NOTE: The graphs are for explanation purpose only. Your machine may be slightly different.

b. Using wire strippers, strip the rubber jacket from both ends of the signal cable to reveal approximately 5.9" (15cm) of wire.
c. Strip the insulation from the ends. d.
NOTE: When connecting the wires, strictly follow the wiring diagram found inside the electrical box cover.
2. Remove the electric cover of the outdoor unit. If there is no cover on the outdoor unit, take o and remove the protection board.

3. Connect the u-lugs to the terminals Match the wire colors/labels with the labels on the terminal block, and firmly screw the u-lug of each wire to its corresponding terminal.

10.Remove the charge hose from the service port.
11. Using hexagonal wrench, fully open both the high pressure and low pressure valves.
OPEN VALVE STEMS GENTLY When opening valve stems, turn the hexagonal wrench until it hits against the stopper. DO NOT try to force the valve to open further.
12.Tighten valve caps by hand, then tighten it using the proper tool.

1. Connect the manifold gauge's charge hose to the service port on the outdoor unit's low pressure valve.
2. Connect the manifold gauge's charge hose to the vacuum pump.
3. Open the Low Pressure side of the manifold gauge. Keep the High Pressure side closed.
4. Turn on the vacuum pump to evacuate the system.
5. Run the vacuum for at least 15 minutes, or until the Compound Meter reads -76cmHG (-1x105Pa).
6. Close the manifold gauge's Low Pressure valve and turn o
7. Wait for 5 minutes, then check that there has been no change in system pressure.

N=2(one-two models), N=3(one-three models), N=4(one-four models), N=5(one-five models). Depending on the length of connective piping or the pressure of the evacuated system, you made need to add refrigerant. Refer to table below for refrigerant amounts to be added:
The standard pipe length is 25' (7.5m).

More recent models now feature automatic correction of wiring/piping errors. Press the "check switch" on the outdoor unit PCB board for 5 seconds until the LED displays "CE", indicating that this function is working, Approximately 5-10 minutes after the switch is pressed, the "CE" disappears, meaning that the wiring/piping error is corrected and all wiring/piping is properly connected.
