4. Turn on the electrical disconnect switch.
5. Observe the operation of the electrical components during
the first heating cycle. Use care as the electrical circuits
are energized.
6. Close the front panel.
Temperature control and contactor operation should be
checked by allowing heater to come up to temperature and
shut off automatically. Use care as the electrical circuits
are energized.
DRAINING THE WATER HEATER
It is recommended that the water heater storage tank be
drained and flushed every 6 months to reduce sediment
buildup. The water heater should be drained if being shut down
during freezing temperatures. See Features And Components
in this manual for the location of the water heater components
described below.
TO DRAIN THE WATER HEATER STORAGE TANK:
1. Turn off the electrical supply to the water heater at the
breaker or disconnect switch.
2. Ensure the cold water inlet valve is open.
3. Open a nearby hot water faucet and let the water run until
the water is no longer hot.
4. Close the cold water inlet valve to the water heater.
5. Connect a hose to the water heater drain valve and
terminate it to an adequate drain.
6. Open the water heater drain valve and allow all the water
to drain from the storage tank.
7. Close the water heater drain valve when all water in the
storage tank has drained.
8. Close the hot water faucet opened in Step 3.
