SECTION VIII: 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 and/or CSA C22.2 Electrical Code.
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. If a flexible line cord and plug is
permitted by local code, then provide a three wire GFI grounding type receptacle within reach of the
control box. Provide a grounded line cord and connect to the black and white power supply and green
ground screw. 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.
