to the heater during ushing operation, so the elements will
not be damaged.
Failure to shut o the heater when draining may damage the
heating elements. Operating a partially lled / empty water
heater could lead to damage from “dry-ring”. Failures due to
such damage ARE NOT covered by warranty.
To ush the tank, attach a hose to the eld installed drain
valve. Close the cold water supply line shut-o valve. Open
the drain valve and hot water faucet(s) to vent heater while
draining. Direct the ow 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-o 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 qualied service contractor for assistance.
Check the area around the water heater for ammable liquids
or combustible materials. If any are found, remove from the
area.
Vacation (Extended shut-o periods)
During extended mild or warm weather periods when hot
water will not be in use, shut o 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 o electric
power to the tank, close the supply line shut-o 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 o 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.

Figure 6 - 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. Rell the tank
with cold water. Open a hot water faucet high in the system to
bleed any air pressure from the system. Water will ow freely
when air is completely bled.
When lling 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 rell 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
qualied service technician to assure that all the equipment
is operating safely and eciently. The owner should make
necessary arrangements with a qualied 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 eciently 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 ush sediment deposits from the bottom of
the heater and lengthen the heater’s service life. Turn o power
