Installing the Main Remote Control:

WARNING: Field wiring connections and electrical grounding must comply with local codes, or in the absence of local codes, with the latest edition of the National Electrical Code, ANSI/NFPA 70, or in Canada, Canadian Electrical Code, CSA C22.1 Part 1.

WARNING: Shock hazard line voltage is present. Before servicing the water heater, turn off the electrical power to the water heater at the main disconnect or circuit breaker. Failure to do so could result in severe personal injury or death.

CAUTION: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify correct operation after servicing.

Electrical Connection

POWER CORD

(Indoor water heaters only):

The electric power supply requirement for this water heater is 120 VAC/60HZ, 2 Amps.

The water heater comes with a three (3) pin power supply cord (INDOOR MODELS ONLY). Use only a power outlet with a ground terminal.

The installation of an electric leakage breaker is recommended.

Keep any excess of the power supply cord on the outside of the water heater.

If local codes require hardwiring, see instructions for “Hardwiring the Electrical Connections”.

HARDWIRING THE ELECTRICAL CONNECTIONS

(Indoor or Outdoor water heaters):

Wiring should be carried out by a qualified electrician in accordance with local codes.

The water heater requires 120 VAC/60Hz and should be properly grounded.

DO NOT connect grounding wire to water pipes, gas pipes, telephone cables, lightning conductor circuits and to grounding circuit of other equipment that carry a ground-fault interrupter.

An ON/OFF switch must be provided and installed for the incoming 120VAC power.

Wire the water heater exactly as shown below. A wiring diagram is also found inside of the cover panel.

A green screw is provided in the junction box (outdoor models only) or in the enclosure (indoor models only) for

a grounding connection.

Connect the live wire to black leg wire and the neutral wire to the white neutral wire.
