The water heater should be inspected at a minimum of annually by a
qualified service technician for damaged components. DO NOT
operate this water heater if any part is found damaged.
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
water heater completely to prevent freezing whenever the building is
left unoccupied during the cold weather months. In order to ensure
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 ensure 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.
When lifting lever of temperature-pressure relief valve, hot water will be
released under pressure. Be certain that any released water does not
result in bodily injury or property damage. The magnesium anode rod
should be inspected periodically and replaced when necessary to prolong
tank life.
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.
