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.
