If the power source capacity for the air-source unit / water-source unit is inadequate or the electric work is not performed properly, it may result
in fire, electric shock, physical injury or death.
Use copper wire only and connect wires tightly to the terminals. Install wiring so that other equipment is not obstructed.
Improper or incomplete connections could result in overheating, fire, electric shock, physical injury or death.
Ensure the power source is disconnected before performing this procedure.
