Part 7 - Maintenance - Westinghouse WEC080C2X030 Use And Care Manual

Figure 7 - Heating Element Detail
NOTE: Repeat Steps 3 - 6 as Necessary for Multiple
Elements
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 elements and
property damage. Such damages ARE NOT covered by
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 elements. 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.
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.
