The Kenmore Elite Hybrid Electric Water Heater is an integrated
heat pump water heater unit, having an 850 Watt compressor and
an external coil heat exchanger with backup electric elements.
When in Efficiency Mode the heat pump draws heat from the
ambient air in the room and transfers it to the water in the tank
through the coil heat exchanger. While in Electric Mode the water
heater functions like a standard electric water heater, relying
on the electric elements to heat the water. A Hybrid Mode is
available that relies primarily on the heat pump to heat the water
while the electric elements only function during high demand
periods. The more often the unit operates using the heat pump,
rather than the elements, the more efficient the unit will be.
The large tank capacities of the Kenmore Elite Hybrid Electric
Water Heaters are intended to take optimal advantage of the
heat pump's capability to heat water for large families or those
having higher than normal hot water requirements. The larger
capacities enable the units to operate in the maximum efficiency
mode more often than other models having lower capacities.
These Electric Heat Pump Water Heaters use about half the
electricity of a comparably sized conventional electric water
heater when operating in the Efficiency Mode and provide up to
1/2 ton cooling capacity and dehumidification. They are designed
for indoor, residential applications for installation in a basement,
garage or utility room.

Removing the Old Water Heater
FIGURE 2.
1. Turn "OFF" electrical supply to the water heater.
The water passing out of the drain valve may be extremely hot.
To avoid being scalded, make sure all connections are tight and
that the water flow is directed away from any person.
4. Check again to make sure the electrical supply is turned
"OFF" to the water heater. Then unplug the water heater
(cord set) or disconnect the electrical supply connection from
the water heater junction box.
5a. FIGURE 6,
If you have copper piping to the water heater, the two
copper water pipes can be cut with a hacksaw approximately
four inches away from where they connect to the water
heater. This wilt avoid cutting off the pipes too short.
Additional cuts can be made later if necessary. Disconnect
the temperature-pressure relief valve drain line. When
the water heater is drained, disconnect the hose from the
drain valve. Close the drain valve. The water heater is now
completely disconnected and ready to be removed.
FIGURE 3.
2. Open a nearby hot water faucet until the water is no longer
hot. When the water has cooled, turn "OFF" the water supply
to the water heater at the water shut-off valve or water meter.
FIGURE 4.
3. Attach a hose to the water heater drain valve and put the other
end in afloor drain or outdoors. Open the water drain valve.
Open a nearby hot water faucet which will relieve pressure
in the water heater and speed draining.
FIGURE 5.
FIGURE 7.
5b. If you have galvanized pipe to the water heater, loosen the
two galvanized pipes with a pipe wrench at the union in each
line. Also disconnect the piping remaining to the water heater.
These pieces should be saved since they may be needed
when reconnecting the new water heater. Disconnect the
temperature-pressure relief valve drain line. When the water
heater is drained, disconnect the hose from the drain valve.
Close the drain valve. The water heater is now completely
disconnected and ready to be removed.
•Burn hazard
• Hotwater discharge.
•Keep hands clear of drain
valve discharge. FIGURE 8.

Mineral Buildup or Sediment MayAccumulate
"This causes the water heater to become
much heavier than normal.
Ifspilled, could cause staining.
Mineral buildup or sediment may have accumulated in the old water
heater. This causes the water heater to be much heavier than normal
and this residue, if spilled out, could cause staining.
Facts to Consider About the Location
You should carefully choose an indoor location for the new water
heater, because the placement is a very important consideration for
the safety ofthe occupants in the building and forthe most economical
use ofthe appliance. This water heater isnot intended for outdoor
installation.
Whether replacing an old water heater or putting the water heater in
a new location, the following critical points must be observed.
Select a location near the center of the water piping system. The
unit must be installed indoors and in a vertical position on a level
surface. The flooring beneath the water heater must be able to
support the weight of the water heater when filled with water (See
Table 1).
IMPORTANT: The water heater must have unrestricted airflow
and requires a minimum installation space of 750 cubic feet. As an
example, a room that has an 8 foot tall ceiling and is 10 feet tong
by 9-1/2 feet wide would contain 760 cubic feet. See the Confined
Space Installation section of this manual for installing the water
heater in spaces of tess than 750 cubic feet.
NOTE: To insure optimal performance and efficiency a minimum
clearance of six (6) inches from the back, left and right sides of the
water heater must be maintained. A minimum of 12 inches from the
front of the unit should be maintained for control access. Service
clearances of twelve (12) inches from the left and right sides are
recommended as a best installation practice.
The water heater should be located in an area not subject to freezing
temperatures. Water heaters located in unconditioned spaces (i.e.,
garages, basements, etc.) may require the water piping, condensate
piping, and drain piping to be insulated to shelter against freezing.
The drain and controls must be easily accessible for operation and
service.
The site location must be free from any corrosive elements in the
atmosphere such as sulfur, fluorine, and chlorine. These elements
are found in aerosol sprays, detergents, bleaches, cleaning
solvents, air fresheners, paint, and vamish removers, refrigerants,
and many other commercial and household products. In addition,
excessive dust and lint may affect the operation of the unit (See
"Cleaning the Filter"section).
The ambient air temperature must also be considered when
installing this unit. In Efficiency Mode the ambient air temperature
must be above 45°F and below 109°R Ifthe ambient air temperature
falls outside these upper and lower limits the electrical elements wilt
activate to meet the hot water demand and the heat pump does not
operate.
NOTE: Local codes and requirements in your area may require the
installation of your water heater be accomplished in a way that the
bottom element iselevated from the floor at least 18 inches. Ensure
that a platform capable of supporting the combined weight of the
water heater and water isused. Reference Table 1.
TABLE 1.
Capacity Packaged Weight (Ibs) Full Weight (Ibs)
60 Gallon 280 lbs 760
80 Gallon 350 lbs 967
This water heater, as well as all water heaters, will eventually
leak. Do not install without adequate drainage provisions so
water flow will not cause damage.
Property Damage Hazard
•All water heaters eventually leak
•Do not installwithout adequate drainage.
WATER HEATERS EVENTUALLY LEAK: Installation of the water
heater must be accomplished in such a manner that if the tank
or any connections should leak, the flow of water will not cause
damage to the structure. When such locations cannot be avoided,
a suitable metal drain pan should be installed under the water
heater. Drain pans are available at your local Sears stores. Such
drain pans must be piped to an adequate drain.
Water heater life depends upon water quality, water pressure
and the environment in which the water heater is installed. Water
heaters are sometimes installed in locations where leakage may
result in property damage, even with the use of a metal drain pan
piped to a drain. However, unanticipated damage can be reduced
or prevented by a leak detector or water shut-off device used
in conjunction with a piped metal drain pan. These devices are
available from some plumbing supply wholesalers and retailers,
and detect and react to leakage in various ways:
•Sensors mounted in the metaldrain pan that trigger analarm or tum
offthe incomingwater tothe water heaterwhen leakage isdetected.
•Sensors mounted in the metal drain pan that turn off the
water supply to the entire home when water is detected in the
drain pan.
•Water supply shut-off devices that activate based on the water
pressure differential between the cold water and hot water pipes
connected to the water heater.
installations in Residential Garages
• Water heater must be located in a
protective area.
INSTALLATION IN RESIDENTIAL GARAGES: The water heater
must be located and/or protected so it is not subject to physical
damage by a moving vehicle.
•The location selection must provide adequate clearances for
servicing and proper operation of the water heater.
insulation Blankets
The use of an insulation blanket on this water heater is not
needed or recommended. The purpose of an insulation blanket
is to reduce the standby heat loss encountered with storage
tank heaters. Your water heater meets or exceeds the National
Appliance Energy Conservation Act standards with respect to
insulation and standby loss requirements, making an insulation
blanket unnecessary.

Confined Space Installation
The heat pump water heaters covered in this manual require a minimum of 750 cubic feet of installation space. When a space
meeting this minimum requirement is not available these units may be installed in spaces with less than 750 cubic feet (confined
spaces) when provisions are made by installing an accessory Outlet Duct Kit and/or touvered grills as described in this section.
Inlet air will be derived from an alternate location inside the building structure through one or more louvered grills or through a fully
louvered door leading into the confined space. The alternate location from where inlet air wilt be derived must provide a minimum of
750 cubic feet of space when using this installation method. When the Outlet Duct Kit is installed outlet air from the unit is redirected
to an alternate location. The alternate location to where outlet air will be redirected must also provide a minimum of 750 cubic feet
of space.
Other configurations are possible when using the Outlet Duct Kit (PN 9910006000) and/or the Inlet Duct Kit (PN 9910005000) with
these water heaters. Consult the installation instructions included with Outlet Duct Kit for additional information. These instructions
are also available on the manufacturer's web site. Contact the distributor where the water heater was purchased for information on
ordering these duct kits.

The outlet air from a unit installed in a garage or drawing
inlet air from a garage or any area where solvents or other
chemicals that emit potentially harmful fumes are stored
or automobiles are located must never be ducted to any
other space inside the building structure. This would include
all occupied and unoccupied spaces such as attics or
basements. Potentially harmful fumes and vapors could be
introduced into living spaces.
A duct termination or grill is required at the end of the duct
run but not supplied with the Outlet Duct Kit. Suitable duct
terminations and grills are readily available from home
centers or HVAC supplies. Terminations must be fitted with
screens or designed to prevent rodents, other pests and
debris from entering the ductwork. If terminated outdoors
or to another space where water or moisture may enter the
ductwork, terminations designed to prevent water or moisture
infiltration must be used.
If outlet ductwork is terminated through a ceiling into an
attic space provision must be made to ensure the ductwork
terminates welt above the insulation line in the attic to
prevent insulation from entering the ductwork. A short section
of 8 inch round metal duct may be used with a suitable duct

Water Piping System
Water temperature over 125°F
(52°C) can cause severe burns
instantly resulting in severe injury
or death.
Children, the elderly, and the
physically or mentally disabled
are at highest riskfor scald injury.
Feel water before bathing or
showering.
Temperature limiting valves are
available.
Read instruction manual for safe
temperature setting.
Piping, fittings, and valves should be installed according to the
installation drawing (Figure 10). If the indoor installation area
is subject to freezing temperatures, the water piping must be
properly insulated.
The water supply pressure should not exceed 80 psi. If this
occurs, a pressure reducing valve with a bypass should be
installed in the cold water inlet line. This should be placed on
the supply to the entire house in order to maintain equal hot and
cold water pressures.
IMPORTANT:
•Heat must not be applied to the water fittings on the
heater as they may contain nonmetallic parts. If solder
connections are used, solder the pipe to the adapter
before attaching the adapter to the hot and cold water
fittings.
•Always use a good grade of joint compound
and be certain that all fittings are tight.
IMPORTANT: DO NOT over apply joint compound.
Piping installation
NOTE: To protect against untimely corrosion of hot and cold
water fittings, it is strongly recommended that di-electric
unions or couplings be installed on this water heater when
connected to copper pipe.
1. Install the water piping and fittings as shown in Figure 10.
Connect the cold water supply (3/4" NPT) to the fitting
marked "Cold". Connect the hot water supply (3/4" NPT)
to the fitting marked "Hot".
2. The installation of unions in both the hot and cold water
supply lines are recommended for ease of removing the
water heater for service or replacement.
3. Some local codes may require, and the manufacturer of
this water heater recommends, installing a mixing valve
or an anti-scald device in the domestic hot water line as
shown in Figure 10. These valves reduce the point-of-use
temperature of the hot water by mixing cold and hot water
and are readily available. Contact a licensed plumber or
the local plumbing authority for more information.
4. Some local codes may require, and the manufacturer
of this water heater recommends, installing a pressure
reducing valve (PRV) in the cold water inlet line where it
enters the residence as shown in Figure 10.
5. If installing the water heater in a closed water system,
install an expansion tank in the cold water line as specified
under "Closed System/Thermal Expansion."
6. Install a shut off valve in the cold water inlet line. It
should be located close to the water heater and be easily
accessible. Know the location of this valve and how to shut
off the water to the heater.
7. Install a discharge line from the temperature and pressure
relief valve in the opening marked "T & P RELIEF VALVE".

8. After piping has been properly connected to the water
heater, open the nearest hot water faucet. Then open the
cold water shut off valve and allow the tank to completely
fill with water. To purge the lines of any excess air and
sediment, keep the hot water faucet open for 3 minutes
after a constant flow of water is obtained. Close the faucet
and check all connections for leaks.
Please note the following:
•The system should be installed only with piping that is
suitable for potable (drinkable) water such as copper,
CPVC, or polybutylene. This water heater must not be
installed using iron piping or PVC water piping.
Use only pumps, valves, or fittings that are compatible with
potable water.
Use only full flow ball or gate valves. The use of valves
that may cause excessive restriction to water flow is not
recommended.
Use only 95/5 tin-antimony or other equivalent solder. Any
lead based solder must not be used.
Piping that has been treated with chromates, boiler seal, or
other chemicals must not be used.
Chemicals that may contaminate the potable water supply
must not be added to the piping system.
Property Damage Hazard
• Avoid water heater damage.
• Install thermal expansion tank if necessary.
oDo not apply heat to cold water inlet.
• Contact qualified installer or service agency.
Condensate Drain Line Installation
Install two 1/2" PVC discharge lines from the condensate drains
(located on the right side near the back). The lines should
terminate a maximum of six inches above an adequate drain.
Do not discharge the condensate drain lines into the metal drain
pan. If no floor drain is available or the drain is above the level
of the condensate line, a condensate pump should be installed.
These pumps are available from local distributors.
When installing the drain line, note the following:
Plastic pipe or tubing must be used to connect the
condensate drain to a suitable drain or condensate pump.
Condensate drain lines should be installed in conditioned
areas only. Install approved insulation on the condensate
drain lines to prevent condensation from forming on the
outside of the drain lines. Condensation drain lines installed
in areas that are subject to freezing temperatures should
be wrapped with a nationally recognized/listed heat tape.
Install per manufacturer's instructions.
• Do not connect condensate drain lines with other drain or
discharge lines into a single (common) pipe or line. Each
line (condensate drain line, temperature and pressure relief
valve discharge pipe, etc) should be independently run to
an adequate drain.
• Slope the condensate drain lines toward the inside floor
drain or condensate pump.
• The condensate drain lines and connections to the drain
piping must comply with all local codes.
• Use appropriate primer and glue to cement the condensate
drain lines to the heat pump drain pan. NOTE: The heat
pump drain pan is ABS and the two condensate drain pipes
should be PVC.
• If a condensate pump is installed it should shut off the
heat pump in the event the condensate pump fails or the
float switch in the pump activates (See "Condensate Pump
Installation" section. )
T&PValve and Pipe Insulation
NOTE: Your water heater is insulated to minimize heat
loss from the tank. Further reduction in heat loss can be
accomplished by insulating the hot water lines from the
water heater.
1. Locate the temperature and pressure relief valve on the water
heater (also known as a T&P relief valve). See Figure 11.
2. Locate the slit running the length of the T&P relief valve
insulation.
3. Spread the slit open and fit the insulation over the T&P relief
valve. See Figure 11. Apply gentle pressure to the insulation
to ensure that it isfully seated on the T&P Relief Valve. Once
seated, secure the insulation with duct tape, electrical tape, or
equivalent. IMPORTANT: The insulation and tape must not
block the discharge opening or hinder access to the manual
relief lever (Figure 11). Ensure a discharge pipe is installed
into the T&P valve discharge opening per the instructions in
this manual.
4. Locate the hot water (outlet) & cold water (inlet) pipes to the
water heater.
5. Locate the slit running the length of asection of pipe insulation.
6. Spread the slit open and slip the insulation over the cold
water (inlet) pipe. Apply gentle pressure along the length d
the insulation to ensure that it is fully seated around the pipe.
Also, ensure that the base of the insulation is flush with the
water heater. Once seated, secure the insulation with duct
tape, electrical tape, or equivalent.
7. Repeat steps 5 and 6 for the hot water (outlet) pipe.
8. Add additional sections of pipe insulation as needed.

must comply with ANSI Z21.22
CSA 4.4 andASME code.
• Properly sized temperature-relief
valve must be installed in opening
provided.
• Can result in overheating and
excessive tank pressure.
• Can cause serious injury or death.
This heater is provided with a properly certified combination
temperature - pressure relief valve by the manufacturer.
The valve is certified by anationally recognized testing laboratory
that maintains periodic inspection of production of listed equipment
of materials as meeting the requirements for Relief Valves for Hot
Water Supply Systems, ANSI Z21.22 • CSA 4.4, and the code
requirements of ASME.
If replaced, the valve must meet the requirements of local codes,
but not tess than a combination temperature and pressure relief
valve certified as indicated in the above paragraph.
The valve must be marked with a maximum set pressure not to
exceed the marked hydrostatic working pressure of the water
heater (150 psi = 1,035 kPa) and a discharge capacity not less
than the water heater input rate as shown on the model rating plate.
(For electric heaters, watts x 3.412 equals Btu/hr input rate)
For safe operation of the water heater, the relief valve must not be
removed from its designated opening nor plugged.
The temperature-pressure relief valve must be installed directly
into the fitting of the water heater designed for the relief valve.
Position the valve downward and provide tubing so that any
discharge will exit only within 6 inches (153 mm) above, or at any
distance below the structural floor. Be certain that no contact is
made with any live electrical part. The discharge opening must
not be blocked or reduced in size under any circumstances.
Excessive length, over 30 feet (9.14 m), or use of more than four
elbows can cause restriction and reduce the discharge capacity
of the valve.
Water Damage Hazard
- Temperature-pressure relief valve discharge
pipe must terminate at adequate drain.
No valve or other obstruction is to be placed between the relief
valve and the tank. Do not connect tubing directly to discharge
drain unless a 6 inch air gap is provided. To prevent bodily
injury, hazard to life, or property damage, the relief valve must
be allowed to discharge water in quantities should circumstances
demand. Ifthe discharge pipe is not connected to a drain or other
suitable means, the water flow may cause property damage.
The Discharge Pipe:
• Shall not be smaller in size than the outlet pipe size of the
valve, or have any reducing couplings or other restrictions.
• Shall not be plugged or blocked.
• Shall be of material listed for hot water distribution.
• Shall be installed so as to allow complete drainage of both the
temperature-pressure relief valve, and the discharge pipe.
• Shall terminate a maximum of six inches above afloor drain or
external to the building. In cold climates, it is recommended
that the discharge pipe be terminated at an adequate drain
inside the building.
Shall not have any valve between the relief valve and tank.
Water temperature over 125°F
(52°0) can cause severe burns
instantly resulting in severe injury
or death.
Children, the elderly, and the
physically or mentally disabled
are at highest riskfor scald injury.
Feel water before bathing or
showering.
Temperature limiting valves are
available.
Read instruction manual for safe
temperature setting
The temperature-pressure relief valve must be manually operated
at least once a year. Caution should be taken to ensure that
(1) no one is in front dor around the outlet of the temperature-
pressure relief valve discharge line, and (2) the water manually
discharged will not cause any bodily injury or property damage
because the water may be extremely hot.
If after manually operating the valve, it fails to completely reset
and continues to release water, immediately close the cold water
inlet to the water heater, follow the draining instructions, and
replace the temperature-pressure relief valve with a new one.

Read instruction manual for safe
temperature setting.
HOTTER WATER CAN SCALD: Water heaters are intended
to produce hot water. Water heated to a temperature which
wilt satisfy clothes washing, dish washing, and other sanitizing
needs can scald and permanently injure you upon contact. Some
people are more likely to be permanently injured by hot water
than others. These include the elderly, children, the infirm, or
physically/mentally handicapped. If anyone using hot water in
your home fits into one of these groups or if there is a local code
or state taw requiring acertain temperature water at the hot water
tap, then you must take special precautions. In addition to using
the lowest possible temperature setting that satisfies your hot
water needs, some type of tempering device, such as a mixing
valve, should be used at the hot water taps used by these people
or at the water heater. Mixing valves are available at plumbing
supply or hardware stores. Follow manufacturers instructions for
installation of the valves, Before changing the factory setting of
the thermostat see Temperature Settings table below.
Never allow small children to use a hot water tap, or to draw
their own bath water. Never leave a child or handicapped person
unattended in a bathtub or shower.
The water heater is adjusted to a temperature setting of no
higher than 120°F when it is shipped from the factory. Water
temperature can be regulated by adjusting the User Interface
Module to the preferred setting as shown in "Adjusting the
User Interface Module/Operational Mode" The preferred
starting point is 120°F. There is a hot water scald potential if
the temperature set point is set too high.
IMPORTANT: Adjusting the set point above 120°F on the User
Interface Module will increase the risk of scald injury in the
times shown below.

Hybrid Mode - This is the default, recommended
setting. Combining high energy efficiency with
reduced recovery time, this mode uses the heat
pump as the primary heating source. The heating
element wilt heat water if demand exceeds
a predetermined level so that the set point
temperature can be recovered more quickly.
Efficiency Mode - Is the most energy efficient
mode. This mode uses the heat pump to heat
water in the tank. The elements are not used
unless the ambient operating temperature
is below 45°F or above 109°F. If hot water
demands are not met in Efficiency Mode it may
be necessary to switch to Hybrid Mode.
Electric Mode - The water heater functions as a
conventional electric unit, relying totally on the
elements to heat the water in the tank. This mode
may be useful in winter to eliminate the output of
cold air from the unit.
Vacation Mode - The controller adjusts the
water temperature to approximately 60°F. This
mode is recommended when the water heater
is not in use for a long period of time. This mode
effectively turns the controller temperature
setting down to a temperature that prevents the
water in the water heater from freezing while
still conserving energy. NOTE: To activate the
Vacation Mode touch the vacation button. To
deactivate Vacation Mode touch the vacation
button. IMPORTANT: The anode protecting the
tank requires power to the unit to operate. Do not
shut off power to the unit for extended periods of
time. If power must be turned off for an extended
period of time, drain the tank completely.
Lock - Holding this button for more than 3
seconds switches the lock mode on or off. When
the User Interface Module is locked a symbol
and "Lock" text will be visible on the display (see
Figure 17).
°F/°C - The button switches the display to show
the set temperature in Fahrenheit or Celsius.

Temperature=Pressure Relief Valve Operation
The temperature-pressure retief valve must be manually operated
at least once a year.
•Burn hazard

, Keep hands clear of drain
valve discharge.
The temperature-pressure relief valve must be manually operated
at least once a year. Caution should be taken to ensure that
(1) no one is in front dor around the outlet of the temperature-
pressure relief valve discharge line, and (2) the water manually
discharged will not cause any property damage or bodily injury.
The water may be extremely hot.

If after manually operating the valve, it fails to completely reset
and continues to release water, immediately close the cold water
inlet to the water heater, follow the draining instructions, and
replace the temperature-pressure relief valve with a new one.
Failure to install and maintain a new properly listed temperature-
pressure relief valve will release the manufacturer from any claim
which might result from excessive temperature or pressure.
If the temperature-pressure relief valve on the appliance weeps
or discharges periodically, this may be due to thermal expansion.
Your water heater may have a check valve installed in the water
line or a water meter with a check valve. Consult your local
Sears Service Center for further information. Do not plug the
temperature-pressure relief valve.
Draining and Flushing
•Burn hazard
Hot water discharge.
Keep hands clear of drain
valve discharge.
It is recommended that the tank be drained and flushed
every 6 months to remove sediment which may build up
during operation. The water heater should be drained
if being shut down during freezing temperatures.
To drain the tank, perform the following steps:
Before removing any access
panels or servicing the water
heater, make sure the electrical
supply to the water heater is
turned "OFF".
• Failure to do this could result in
death, serious bodily injury, or
property damage.
1,
2.
3.
Place the water heater in Standby Mode by pressing the
power button on the user interface module.
Turn off the power to the water heater at the circuit breaker/
fuse box.
Open a nearby hot water faucet until the water is no longer
hot.
4,
5.
6,
7,
8,
Close the cold water inlet valve.
Connect a hose to the drain valve and terminate it to an
adequate drain or external to the building.
Open the water heater drain valve and allow all of the
water to drain from the tank. Flush the tank with water as
needed to remove sediment.
Close the drain valve, refill the tank (open the cold water
inlet valve), and restart the heater as directed in this manual.
IMPORTANT: Do not turn on power to the water heater
unless it is completely filled with water. To ensure that the
tank is full, open a hot water faucet and allow the water to
run until the air is purged and the water flows uninterrupted
from the faucet.
Press the power button to turn the water heater on.
NOTE: The water heater will conduct a system diagnostic
prior to operation.
If the water heater is going to be shut down for an extended
)eriod, the drain valve should be left open.
Improper installation and use may result
in property damage.
• Fill tank with water before operation.
Never use this water heater unless it is completely full of water.
To prevent damage to the tank and heating element, the tank
must be filled with water. Water must flow from the hot water
faucet before turning "ON" power.
Element Removal/Replacement
Before removing any access
panels or servicing the water
heater, make sure the electrical
supply to the water heater is
turned "OFF".
Failure to do this could result in
death, serious bodily injury, or
property damage.
Replacement heating elements must be of the same style and
voltage/wattage rating as the ones originally in the water heater.
This information can be found on the flange or terminal block of the
element or on the water heater data plate.
IMPORTANT: Before replacing any element confirm that you
have the correct replacement element (wattage). This water
heater has a 4500 watt upper element and a 2000 watt lower
element. DO NOT replace the element(s) with a wattage
different than the ones specified for the upper and/or lower
element.
IMPORTANT: Using an element greater than 2000 watts in
place of the lower element will damage the water heater.
