Completely fill the tank with water and check all connections for
leaks. Open the nearest hot water faucet and let it run for three (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.
Solar Installation
If this water heater is used as a solar storage heater or as a
backup for the solar system, the water supply temperatures to
the water heater tank may be in excess of 120°F. A mixing valve
or other temperature limiting valve must be installed in the water
supply line to limit the supply temperature to 120°F.
NOTE: Solar water heating systems can often supply water with
temperatures exceeding 180°F and may result in water heater
malfunction.
CAUTION:
LABEL ALL WIRES PRIOR TO
