Wiring

If local codes permit, the water heater may be connected to electric service with the power cord provided (DO NOT use an extension cord).

A grounding receptacle is required.

If local codes do not permit the use of cord connections, a 120 V, 50/60 Hz power supply, with suitable disconnecting means, must be connected to the black and white leads in the heater control enclosure.

A knock-out hole is provided to permit use of conduit or metal-clad cable connectors.

The maximum current draw is approximately 5.0 amps.

The water heater must be electrically grounded in accordance with local codes, or, in the absence of local codes, in accordance with latest edition of the National Electric Code ANSI/NFPA No. 70; or in Canada, the latest edition of the Canadian Electric Code CSA C22.1.

NOTICE: It is not recommended that this unit be installed on a GFCI circuit.
