WIRING PRECAUTIONS
See Figs. 14 and 15 for Connection Diagrams.
NOTE ON CIRCUIT BREAKER: When the maximum current of the unit is
more than 16A, a circuit breaker or leakage protection switch with
protective device shall be used (purchased separately). When the
maximum current of the unit is less than 16A, the power cord of unit
shall be equipped with plug (purchased separately). In North
America, the appliance should be wired according to NEC and CEC
requirements.
INDOOR UNIT WIRING
1. Prepare the cable for connection
a. Using wire strippers, strip the rubber jacket from both ends of the
signal cable to reveal about 5.9in (15cm) of the wire.
b. Strip the insulation from the ends of the wires.
c. Using a wire crimper, crimp the u-lugs to the ends of the wires.
2. Open the front panel of the indoor unit. Using a screw driver, remove
the cover of the electric control box on your indoor unit.
3. Thread the power cable and the signal cable through the wire outlet.
4. Connect the u-lugs to the terminals.
Match the wire colors/labels with the labels on the terminal block.
Firmly screw the u-lug of each wire to its corresponding terminal.
Refer to the Serial Number and Wiring Diagram located on the cover
of the electric control box.

WARNING
BEFORE PERFORMING ANY ELECTRICAL WORK, READ
THE FOLLOWING WARNINGS.
• All wiring must comply with local and national electrical codes,
regulations and must be installed by a licensed electrician.
• All electrical connections must be made according to the Electrical
Connection Diagram located on the panels of the indoor and outdoor
units.
• If there is a serious safety issue with the power supply, stop work
immediately. Explain your reasoning to the client, and refuse to install
the unit until the safety issue is properly resolved.
• Power voltage should be within 90-110% of rated voltage.
Insufficient power supply can cause malfunction, electrical shock, or
fire.
• Installation of an external surge suppressor at the outdoor disconnect
is recommended.
• If connecting power to fixed wiring, a switch or circuit breaker that
disconnects all poles and has a contact separation of at least 1/8in
(3mm) must be incorporated in the fixed wiring. The qualified
technician must use an approved circuit breaker or switch.
• Only connect the unit to an individual branch circuit. Do not connect
another appliance to that outlet.
• Make sure to properly ground the unit.
• Every wire must be firmly connected. Loose wiring can cause the
terminal to overheat, resulting in product malfunction and possible
fire.
• Do not let wires touch or rest against refrigerant tubing, the
compressor, or any moving parts within the unit.
• If the unit has an auxiliary electric heater, it must be installed at least
40in (1 m) away from any combustible materials.
• To avoid getting an electric shock, never touch the electrical
components soon after the power supply has been turned Off. After
turning off the power, always wait 10 minutes or more before you
touch the electrical components.
• Make sure that you do not cross your electrical wiring with your
signal wiring. This may cause distortion, interference or possibly
damage to circuit boards.
• No other equipment should be connected to the same power circuit.
• Connect the outdoor wires before connecting the indoor wires.
Before performing any electrical or wiring work, turn off the main
power to the system.
