Installation / Operation Instruction Manual

MAINTENANCE
Shut off the electric power whenever the water supply is turned 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 heater through the drain valve until water runs clear. Drain it at least
once a month. 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 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 who 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.
