The water heater’s electrical components are pictured and identified on page 7. The following describes the heater circuits and

includes wiring diagrams. All heater circuits are designed for 60/50 hertz alternating current. The water heater circuit wiring is 12

AWG, AWM, or TEW type, rated 600 volts, 105°C. Fusing consists of three 30 amp fuses for each contactor. Fusing is an optional

feature for Canadian models.
