ELECTRICAL WIRING
Power supply and wiring requirement
1. Power frequency of air conditioner should be 60 Hz, voltage: AC 208/230V. If voltage is over, may cause damage
to electric equipment. Voltage that is too low, this may cause the compressor to shake, causing damage to the
cooling system.
2. User power supply should be provided to a reliable grounded connection. (see grounding requirement)
Electrical connection requirement
1. Should have a reliable grounded connection (see ground connection requirements)
2. Wire screws should be firmly tightened. Any damaged screw should be replaced. (Self-tapping screws should
NOT be used on an electrical connection.)
3. The provided wire should be used. Do not change the wire, length and or the ends 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.
Notes:
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 regulation.
HOW TO CONNECT WIRING TO THE TERMINALS
For solid core wiring (or F-cable)
1. Cut the end of the wire using wire cutters, then strip the
insulation about 15/16" (25mm) to expose the solid wire.
2. Using a screwdriver, remove the terminal screw(s) on the
terminal board.
3. Using needle nosed pliers, bend the solid wire to form a
loop suitable for the terminal screw.
4. Shape the loop wire properly, place it between the terminal
boards, and tighten the terminal screw to hold the solid wire
loop securely.
For strand wiring
1. Cut the wire end using wire cutters, then strip the insulation
to about 3/8" (10mm) to expose the solid wire.
2. Using a screwdriver, remove the terminal screw(s) on the
terminal board.
3. Using a round terminal fastener or plier, securely clamp a
round terminal to each stripped wire end.
4. Position the round terminal wire, replace and tighten the
terminal screw using a screwdriver.
ATTENTION :
An all-pole disconnection switch, with a contact separation of at least 3mm at all poles, should be connected in fixed
wiring.
