Power supply and wiring requirement
AC 208/230V. If voltage is over, may cause the parts of electric equipment to become damaged. If the voltage
is too low, this may cause the compressor to shake thus causing damage to the cooling system.
2) User power supply should be provided a reliable grounding connect. (see earth requirement)
1) Power frequency of air conditioner should be 60 Hz, voltage:
1) Should have a reliable earth connection (see earth connection requirement)
2) Screw of wire should be tight, damaged screw should be changed. ( Self tapping screws cannot be used on
an electrical connection.)
3) The provided wire should be used. Please do not change the wire, length and end of it. If you need to adjust,
please contact the local service center.
4) Please do not connect the plug with the non-plug wire by yourself.
5) Indoor and outdoor electrical connecting wire should not be pulled too tightly or twisted.

INDOOR UNIT CONTROL BOX & WIRING TERMINALS
Remove the control box cover and install the connection cord to the wiring terminals. Must match terminal
number for each wire at both indoor unit and outdoor unit wiring terminal.
Note:
* The temperature of refrigerant circuit will be high, please keep the interconnection cable away from the copper
tube.
* An all-pole disconnection device which has at least 3mm separation distance in all pole and a residual current
device(RCD)with the rating of above 10mA shall be incorporated in the fixed wiring according to the national rule.
CONNECTION OF REFRIGERANT PIPE
* Besure to use both a spanner and torque wrench together as shown in the drawing, connecting or
disconnecting pipes to/from the unit.
* Refer to table 1 to determine the proper tightening torque (over tightening may damage the flare and cause
leaks.)
* When connecting the flare nut, coat the flare both inside and outside with refrigerating machine oil and initially
tighten by hand 3 or 4 turns.
* Check the pipe connector for gas leaks, then insulate it as shown in the drawing below.
* Use sealing pad (11) to wrap joint between gas pipe and the insulation(8).
* The enclosure of the appliance shall be marked by word, or by symbols, with the direction of the fluid flow.
