POWER AND WIRING INSTALLATION
1. Before obtaining access to terminals, all electrical supply circuits must be disconnected.
2. Always use an independent circuit and provide an independent circuit breaker to supply power to the system.
3. Use a circuit breaker with adequate capacity to meet the requirements of the total system.
4. All circuit breakers or fuses for the indoor and outdoor units should be installed per the National Electric Code
(NEC) and local regulations.
5. Electrical wiring must be completed in accordance with NEC, local laws, and regulations of the electric
company so that the system will operate properly.
6. Provide a GFI circuit breaker at the electrical panel in accordance with the NEC and the local electrical
company standards.
7. Connect the power supply firmly to the terminal block. Improper installation may cause a fire.
1. The main power supplies are high-voltage, while the communication wire and the Tether Controller are low-
voltage. They should be installed separately to avoid electromagnetic interference.
2. High-voltage and low-voltage lines should pass through separate rubber rings at electric box covers.
3. If the indoor unit communication wire (to the outdoor unit) and power wire are connected incorrectly, the air
conditioner may be damaged.
4. Ground both indoor unit and outdoor unit to earth ground in accordance with the applicable local and national
codes.
