POWER AND WIRING INSTALLATION
WARNING
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.
CAUTION
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.
