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 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.

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.
