Completely drain the water heater before removing and replacing
a heating element. Failure to do so will result in a leakage of water
and property damage, and could possibly result in moderate to
severe personal injury or death.
Water drained from the water heater may be scalding hot. Take
care to avoid scalding. Wear gloves and safety glasses, and direct
water to a safe drainage location. Failure to comply with this
warning could result in property damage, severe personal injury,
or death.
Step #3 - Remove the element with a 1 1/2" socket wrench or
element tool.
Step #4 - Ensure thread and opening are completely free of debris.
Use a nylon brush to clear away any debris.
Step #5 - Put a small amount of NSF approved lubricant and sealant
on the appropriate gasket and/or washer for the installation. Put the
gasket and/or washer on the element.
Step #6 - Screw the element clockwise into the tank, and tighten
with the 1 1/2" socket wrench or element tool. Be sure O-ring seats
properly.
Step #7 - Open the main cold water inlet. If the water heater has
been isolated from the system, open the valves. Refill the tank with
cold water. Open a hot water faucet high in the system to bleed
any air pressure from the system. Water will flow freely when air is
completely bled.
When filling the water heater, open a hot water tap to release air
in the tank and piping. The tank must be full of water before the
heater is turned on. Failure to ensure the water heater is full before
turning it on will result in damage to the water heater, and could
result in property damage, serious personal injury, or death. Such
damages ARE NOT covered by water heater warranty.
Step #8 - Pressure check the tank for leaks around element. If no
leaks are found, use a Phillips Head screwdriver to connect the wires
to the element.
Step #9 - Turn power back on to the water heater.
Failure to refill the tank before restoring power to the water
heater will result in damage to the heating element and property
damage. Such damages ARE NOT covered by warranty.
D. Anode Rod
This water heater is equipped with a magnesium anode rod. Anode
rods are sacrificial components that counteract water chemistry to
minimize or eliminate tank corrosion.
The anode rod should be inspected annually and replaced as
necessary to prolong tank life. Have the supply water quality
professionally analyzed, as local water conditions will influence the
duration for inspection and replacement of the anode rod.
The use of a water softener may increase the speed of anode
consumption. More frequent inspection of the anode is needed
when using softened or treated water.
Water with high sulfate and/or mineral content can produce a
rotten egg odor in heated water. Chlorinating the water supply may
minimize this problem.
NOTE: Do not remove the anode rod from an operating water
heater. Operating the water heater without the anode rod will
shorten the life of the tank and VOID the warranty.
Part 7 - Maintenance
Considerations
•
To avoid electric shock, disconnect electrical supply before
performing maintenance.
•
To avoid severe burns, allow heater to cool before performing
maintenance.
NOTE: In addition to the routine maintenance detailed in this manual,
this water heater should be inspected annually by a qualified service
technician to assure that all the equipment is operating safely and
efficiently. The owner should make necessary arrangements with a
qualified heating contractor for periodic maintenance of the heater.
Installer must also inform the owner that lack of proper care and
maintenance may result in a hazardous condition, premature heater
failure, and void the warranty.
Routine preventative maintenance ensure the water heater operates
safely and efficiently over its service life. The Owner / User may
perform the maintenance activities described below.
Monthly (Every two weeks in hard water locations)
It is recommended that a few quarts of water be drained from the
heater. This will flush sediment deposits from the bottom of the heater
and lengthen the heater's service life. Turn off power to the heater
during flushing operation, so the elements will not be damaged.
Failure to shut off the heater when draining may damage the heating
element. Operating a partially filled / empty water heater could lead
to damage from "dry-firing". Failures due to such damage ARE NOT
covered by warranty.
Water drained from the water heater may be scalding hot. Take care
to avoid scalding. Wear gloves and safety glasses, and direct water to
a safe drainage location. It is recommended to turn power off to the
water heater and run water at a hot water faucet until it cools BEFORE
draining water from the heater. Failure to comply with this warning
could result in property damage, severe personal injury, or death.
To flush the tank, attach a hose to the field installed drain valve. Close
the cold water supply line shut-off valve. Open the drain valve and hot
water faucet(s) to vent heater while draining. Direct the flow of water
to a drain or bucket where it will not cause damage.
Flush until water runs clear to complete this operation. Close drain
valve and reopen the supply line shut-off valve. Close the hot water
faucet(s) once all air has been bled from the system (when water runs
freely). Make certain that the heater is completely full of water before
restoring power.
Periodically (At least twice a year)
Check around the water heater and related plumbing for leaks. If
the combination temperature and pressure relief valve discharges
periodically, or water is leaking from around the heating elements,
there may be a problem with your water system. DO NOT ATTEMPT
TO REPAIR LEAKS YOURSELF! Contact a qualified service contractor for
assistance.
Check the area around the water heater for flammable liquids or
combustible materials. If any are found, remove from the area.
Vacation (Extended shut-off periods)
During extended mild or warm weather periods when hot water will
not be in use, shut off the electric power to the tank. When hot water is
needed again, restore power to the water heater.
During extended cold weather periods when hot water will not be
in use and prone to freezing conditions, shut off electric power to
the tank, close the supply line shut-off valve, open the drain valve
and drain the water heater to a safe drainage location (as detailed
previously). Once drained, close the drain valve. When hot water is
needed again, restore the water supply to the tank. Once the tank is
full, restore power.
