WARNING! Before servicing or cleaning
the water heater, disconnect the water
heater from the electrical outlet.
Approximately once per year, it is
advisable to descale the heating element
and to check the condition of the
magnesium anode, replacing it if the
diameter is less than .39” (10 mm). (See
changing the anode rod).
WARNING! The temperature/pressure
relief valve must be manually operated at
least once per year. Caution should be
taken to ensure that:
1. No one is near the
temperature/pressure relief valve
discharge pipe.
2. The water discharged will not cause
any bodily injury or property damage. The
water may be extremely hot.
If after manually operating it, the valve
fails to completely reset and continues to
release water, immediately close the cold
water inlet to the heater. Replace the
temperature/pressure valve with a new
one.
Failure to install and maintain a properly
functioning and properly listed
temperature/pressure relief valve will
release the manufacturer and distributor
of this water heater from any claim which
might result from excessive temperature
or pressure.
