Shut off the electric power whenever the water supply to the water heater is off.
Shut off the electric power and water supply, drain the heater completely to
prevent freezing whenever the building is left unoccupied during the cold
weather months. In order to insure efficient operation and long tank life, drain
the water heater at least once a month through the drain valve until the water
runs clear. Failure to do this may result in noisy operation and lime and
sediment buildup in the bottom of the tank. Check the temperature-pressure
relief valve to insure that the valve has not become encrusted with lime. Lift the
lever at the top of the valve several times until the valve seats properly without
leaking and operates freely.
The following, maintenance should be performed by a qualified service
technician at the minimum periodic intervals suggested below. In some
installations, the maintenance interval may be more frequent depending on the
amount of use and the operating conditions of the water heater. Regular
inspection and maintenance of the water heater will help to insure safe and
reliable operation.
1. Annually, check the operation of the thermostat(s).
2. Bi-annually, check the seal around the heating elements for leaks. If there
is any sign of leaking, disconnect the power supply to the water heater and
contact the plumbing professional that installed this water heater or a
qualified service technician.
