MAINTENANCE
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 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.
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.
IMPORTANT
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.
WARNING
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.
