A correct polarity 120V 50/60 Hz power supply with suitable disconnect means, must be connected to the black and white leads
provided. The maximum current draw by these models is 7 Amps. The water heater, when installed, must be electrically grounded in
accordance with local codes or, in the absence of local codes, with the National Electrical Code, ANSI/NFPA 70 in the United States,
or CSA C22.1 Electrical Code, in Canada. Improper grounding or polarity may result in abnormal operation of the unit.
