Electric Shock Hazard
WARNING
Before plugging in the water heater, always make sure:
• The voltage and frequency correspond to that specified
on the water heater wiring diagram.
• The electrical outlet has the proper overload fuse or
breaker protection.
1. The unit must be connected to a 120VAC power
supply. A dedicated circuit is preferred.
2. The water heater must be properly grounded.
3. This water heater is a polarity sensitive appliance and
will not operate properly if the power supply polarity
is reversed.
4. Do not use a GFI outlet.
Note: Always reference the wiring diagram for the correct
electrical connections.
After making all electrical connections, completely fill the
tank with water and check all connections for leaks. Open
the nearest hot-water faucet and let it run for 3 minutes to
purge the water lines of air and sediment and to ensure
complete filling of the tank. The electrical power may then
be turned on. Verify proper operation after servicing. See
also “Installation Checklist”.
