SECTION VII: ELECTRICAL CONNECTIONS

WARNING

Turn off or disconnect the electrical power supply to the water heater before servicing. Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing.

All electrical wiring must be installed and grounded in accordance with local codes, or in the absence of local codes, the National Electrical Code, ANSI/NFPA 70 (latest edition) and/or CSA C22.2 Electrical Code (latest edition).

The water heater must be wired to a 120 VAC, 60 Hz, 15A power supply. The water heater should be connected to a GFI outlet and wired on a separate circuit and breaker. A strain relief will be required for the line cord. Do not plug the line cord into a receptacle that can have the power supply interrupted by a switch that is used to control lights or another appliance.

If wiring in conduit is required, install an electrical conduit connector. A disconnect switch should be provided near the water heater for servicing. Connect the wires exactly as shown in the wiring diagram of this manual and on the inside cover panel. The black wire is the hot leg; the white wire is neutral. A green screw is provided in the junction box for the green wire ground connection.

CAUTION

Do not energize the electric circuit before the water heater tank is filled with water.
