Installing the water heater
Thermal Expansion
Determine if a check valve exists in the
inlet water line. Check with your local
water utility. It may have been installed in
the cold water line as a separate back flow
preventer, or it may be part of a pressure
reducing valve, water meter or water softener.
A check valve located in the cold water inlet
line can cause what is referred to as a “closed
water system”. A cold water inlet line with
no check valve or back flow prevention
device is referred to as an “open” water
system.
As water is heated, it expands in volume and
creates an increase in the pressure within the
water system. This action is referred to as
“thermal expansion”. In an “open” water
system, expanding water which exceeds the
capacity of the water heater flows back into
the city main where the pressure is easily
dissipated.
A “closed water system”, however,
prevents the expanding water from flowing
back into the main supply line, and the
result of “thermal expansion” can create
a rapid and dangerous pressure increase in
the water heater and system piping. This
rapid pressure increase can quickly reach
the safety setting of the relief valve, causing
it to operate during each heating cycle.
Thermal expansion, and the resulting rapid
and repeated expansion and contraction of
components in the water heater and piping
system can cause premature failure of the
relief valve, and possibly the heater itself.
Replacing the relief valve WILL NOT
correct the problem!
The suggested method of controlling thermal
expansion is to install an expansion tank in
the cold water line between the water heater
and the check valve (refer to the illustration
on the next page). The expansion tank is
designed with an air cushion built in that
compresses as the system pressure increases,
thereby relieving the over pressure condition
and eliminating the repeated operation of the
relief valve. Other methods of controlling
thermal expansion are also available. Contact
your installing contractor, water supplier or
plumbing inspector for additional information
regarding this subject.
Water Supply Connections
Refer to the illustration on the next page for
suggested typical installation. The installation
of flexible connectors is recommended on
the hot and cold water connections. Flexible
connections provide vibration isolation and
allow the water heater to be easily disconnected
for servicing if necessary. The HOT and
COLD water connections are clearly marked
and are 3/4in. NPT on all models. Install a
shut-off valve in the cold water line near the
water heater.
See page 15 on "To Fill The Water Heater".
NOTICE: DO NOT apply heat to the
HOT or COLD water connections. If
sweat connections are used, sweat tubing
to adapter before fitting adapter to the
water connections on heater. Any heat
applied to the water supply fittings will
permanently damage the dip tube and/or
heat traps.
Condensate Drains
Consult local codes or ordinances for
specific requirements. Refer to page 5.
IMPORTANT: When making drain fitting
connections to the drain tubing, use a thin
layer of piping tape or silicone and install
hand tight.
IMPORTANT: When making drain fitting
connections to the drain tubing, DO NOT
overtighten. Overtightening fittings can split
pipe connections on the drain pan.
• This unit is equipped with a 3/4" NPT
female primary condensate connection.
Use MIP fittings for connections.
• DO NOT reduce drain line size less
than connection size provided on
condensate drain.
• All drain lines must be pitched
downward away from the unit a
minimum of 1/8" per foot of line to
ensure proper drainage.
• Drain lines must include a P-trap if
connected to a sewer pipe.
• If no drain is available, then a common
condensate pump with a capacity no less
than 2 gallon per day must be installed.
• DO NOT allow condensate to drain into
the water heater drain pan.
• The drain line should be insulated where
necessary to prevent sweating and
damage due to condensate forming on
the outside surface of the line.

Guidelines for Installing a Heat Pump Water Heater (HPWH) with an
On-Demand Recirculation System
A recirculation system can help provide hot water more quickly to the xtures in a home. However, it also places
additional demand on the water heater and, if installed incorrectly, may reduce the amount of hot water available
and / or signicantly reduce the performance and life of your water heater. To optimize the performance of an
HPWH with a recirculating system, it is recommended to only use an on-demand system.
The purpose of this document is to provide guidelines for installing an on-demand recirculation system with our
HPWH. We provide the following guidance for you to determine if a Rheem HPWH will perform for your specic
needs. This document complies with CA Title 24 Guidelines. Please refer to all local and state codes.
DANGER: water temperatures above 120°F can cause severe burns instantly or death from scalds.
An on-demand recirculation system or pump can be used with a Rheem HPWH using either 240v or 120v. The
recirculation system or pump must comply with local and state codes (and CA Title 24 Guidelines when installed
in CA).
Hot water supply and return piping insulation with R-value of at least 7.7 is strongly recommended to save energy
and minimize electrical usage, extending the water heater’s life. Please refer to your local code for insulation
values.
Installation Parameters:
• On-demand recirculation system should include temperature sensors; recommended return temperature should
be 102°F
• Dedicated return line or cross-over valve can be used (refer to manufacturer’s installation instructions)
• Add insulation to the return line to decrease heat loss
• On-demand pump ow rate should not exceed 6gpm; recommended ow rate is 3gpm
• Refer to your on-demand recirculation pump manufacturer for all installation instructions
Notice:
• Failure to follow these instructions might result in less available hot water and/or lower the unit’s
performance and eciency, increasing energy / utility consumption.
• Depending on conditions associated with the specic application, anticipated energy savings could be
signicantly impacted.
• Using an uncontrolled recirculation loop may cause the water heater to run excessively.
• Be sure the water heater is properly installed in accordance with local codes and the provided installation
instructions.

management, and demand response systems. Connectivity is provided through the
via wireless (Wi-Fi).
!
WARNING: DO NOT
turn on the electrical
supply or operate this
water heater unless it is
completely full of water.
The tank must be full of
water before water
heater is turned on. The
water heater warranty
does not cover damage
or failure resulting from
operation with an empty
or partially empty tank.
LeakGuard
TM
If the water heater is equipped with
built-in leak detection and automatic
water shut off valve. The leak detection
device (LeakSenseTM) detects the
presence of water and immediately
alerts the electronic control as the
EcoNet app on the cellular phone.
When water is detected, the electronic
controls will shut down the heating
elements and the automatic water shut
off valve closes.
Self Check
The automatic water shut off valve has
a self check feature which runs every 30
days once the water heater is powered
on. This feature works by closing and
reopening the automatic water shut off
valve. In case the valve fails to reopen,
the water heater will be DISABLED.
The water heater gives alert when the
automatic water shut off valve fails to
close.
!
WARNING: Failure
to follow the instructions
provided in this manual
may permanently
damage the unit and
void the manufacturer’s
warranty.
!
WARNING: The
pressure rating of the
relief valve must not
exceed 150 PSI, the
maximum working
pressure of the water
heater as marked on the
rating plate.
!
WARNING: DO NOT connect other plumbing to the T&P plumbing; it must go
directly to a suitable open drain. DO NOT connect the T&P plumbing to the
condensate plumbing.
Relief Valve
The btu/h rating of the relief valve must
not be less than the input rating of the
water heater as indicated on the rating
label located on the front of the heater
(1 watt=3.412 btu/h).
Connect the outlet of the relief valve
to a suitable open drain so that the
discharge water cannot contact live
electrical parts or persons and to eliminate
potential water damage.
Piping used should be of a type approved
for hot water distribution. The discharge
line must be no smaller than the outlet of
the valve and must pitch downward from
the valve to allow complete drainage (by
gravity) of the relief valve and discharge
line. The end of the discharge line should
not be threaded or concealed and should
be protected from freezing. No valve of
any type, restriction or reducer coupling
should be installed in the discharge line.
A new combination temperature and pressure relief valve, complying with the Standard for Relief Valves
for Hot Water Supply Systems, ANSI Z21.22/CSA 4.4, is factory installed and must remain in the opening
provided and marked for the purpose on the water heater. No valve of any type should be installed between
the relief valve and the tank.
NOTE: The shut off valve is not pre-installed.

Installing the water heater
Insulation blankets, available to the general
public, for external use on electric water heaters
are not necessary. The purpose of an insulation
blanket is to reduce the standby heat loss
encountered with storage tank heaters. This
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.
The manufacturer’s warranty does not cover
any damage or defect caused by installation,
attachment or use of
any type of energy saving or other unapproved
devices (other than those authorized by the
manufacturer) into, onto or in conjunction
with the water heater. The use of unauthorized
energy saving devices may shorten the life of
the water heater and may endanger life and
property.
The manufacturer disclaims any responsibility
for such loss or injury resulting from the use of
such unauthorized devices.
CAUTION: If local codes require the
application of an external insulation
blanket to this water heater, pay careful
attention to the following so as not to
restrict the proper function and operation
of the water heater:
DO NOT cover the operating or warning
labels attached to the water heater or attempt
to relocate them on the exterior of insulation
blanket.
DO NOT cover air openings on both sides
of the water heater .
DO NOT cover the Controller Assembly,
temperature and pressure relief valve or
drain valve.
Inspect the insulation blanket frequently.

Installing the water heater
Always check with local building and
HVAC codes before designing the duct
system
The water heater may be ducted to the out-
doors or another space as described in these
instructions. Ducting congurations that does
not comply with these
guidelines are not supported.
DO NOT connect this water heater to
existing duct work; it must be ducted
separately from other appliances.
Ducting approved for HVAC applications
is required.
Ducting must be adequately supported
along both vertical and horizontal lengths.
UL Certied terminations must be used
for ducting to the outside. These termi-
nations have been evaluated to ensure
there is sucient protection from rain
water entry and resistance to air ow is
minimized.
Indoor registers approved for HVAC ap-
plications is required.
Rigid ducting must be isolated from
oor joists or other structural members
to minimize the transmission of noise
and vibration. A short section (12 inch
minimum) of exible duct must be used
between the water heater and rigid duct-
ing as an isolation method.
Ducting must be insulated per HVAC
codes (to prevent condensation).
Ensure cold air exhaust is suciently
away from structures to prevent
condensation on surfaces.
Maximum heater performance is obtained
by lowering the resistance to air ow
(regular lter maintenance is benecial)
and providing the unit with warm moist
air.
Add duct tape if air leaks are detected.
Considerations when planning the duct
system:
Run the ducting the most direct route
possible.
Limit the number of elbows/bends.
Use the largest duct size possible.
Use the largest termination possible.
Consider placement and direction of
terminations (reduce recirculation of
exhaust into the intake).
Calculated length of duct is the length
on the inlet plus the length on the outlet.
Any combination of duct lengths on the
inlet and outlet is supported up to the
maximum duct length (Table 1).
The inlet ducting connections on the
water heater accept 8 inch diameter
ducting, while the outlet ones accept 10
inch diameter ducting. No additional
adaptors are needed.
7 inch, 6 inch, 5 inch diameter ducting
is supported. Table 1 lists the total feet
of ducting allowed. For duct diameters
smaller than 8 inch diameter, Table 1
takes into account the duct reducer(s) and
up to 10 feet of 8 inch rigid ducting (two
elbows) before the duct reducer(s) at the
unit.Duct Reducers must be installed
within 10 feet (two elbows) of the unit or
within 2 feet of the end of the duct.

Installing the water heater
Elbows/Bends
Rigid duct elbows and flex bends greater than 45°
is considered an elbow.
Flexible ducting bends’ inner radius cannot be less
than its diameter. If bends with tighter radiuses are
needed, a rigid elbow must be used.
Maximum number of elbows/bends allowed are
shown in [brackets] in Table 2.
Terminations/Registers
Table 2 equivalent feet for terminations includes the
rodent screen.
For terminations and registers with smaller
diameters than the duct diameter, Table 2 accounts
for the duct reducer and termination/register.
Smaller diameter terminations and registers with
more than a 2 ft. connection is not supported.
Damper
If ducting to the outside using an exhaust duct
only (no intake duct), an approved Rheem damper
should be installed no further than 10 ft. of rigid
ducting total (two elbows equivalent) from the unit.
This prevents outside air from coming into the
living space. If ducting air from the outside to the
inlet of the heater, no provision is made to prevent
outside air from flowing into the living space.

Operating the water heater
The water heater is equipped with a
temperature limiting control (ECO)
that is located above the upper heating
element in contact with the tank
surface. If for any reason the water
temperature becomes excessively high,
the temperature limiting control (ECO)
breaks the power circuit to the heating
element. Once the control opens, it must
be reset manually.
CAUTION: The cause of the high
temperature condition must be
investigated by qualified service
technician and corrective action must
be taken before placing the water
heater in service again.
To reset the temperature limiting
control: (Refer to Illustration in Cavity
Insert section):
Disconnect all power to unit before
starting maintenance.
Remove the upper cavity cover and
insulation.
Press the red RESET button.
Replace the insulation, jacket
access panel and plastic housing
before turning on the power to the
water heater.
!
DANGER: There is a
hot water scald potential if
the thermostat is set too
high. Households with
small children, disabled, or
elderly persons may
require a 120°F (49°C) or
lower thermostat setting to
prevent contact with HOT
water.
Water Temperature Setting
The temperature of the water in the water
heater can be regulated by selecting the
desired temperature on control display.
Safety and energy conservation are
factors to be considered when selecting
the water temperature setting of the water
heater. The lower the temperature setting,
the greater the savings in energy and
operating costs.
To comply with safety regulations the
temperature is factory set at 120°F (49°C)
or less where local codes require. This is
the recommended starting point.
Water temperatures above 125°F (52°C)
can cause severe burns or death from
scalding. Be sure to read and follow the
warnings outlined in this manual and on
the label on the water heater. This label is
located on the front of the water heater.
Mixing valves are recommended for
reducing point of use water temperature
by mixing hot and cold water in branch
water lines. It is recommended that
a mixing valve complying with the
Standard for Temperature Actuated
Mixing Valves for Hot Water Distribution
Systems, ASSE 1017 be installed. See
page 3 for more details and contact a
licensed plumber or the local plumbing
authority for further information.
When used in demand response
applications a thermostatic mixing valve
conforming to ASSE 1017 shall be
installed on the hot water supply line
following all manufacturer installation
instructions. See page 38 for additional
installation information.
The chart on the page 3 may be used as
a guide in determining the proper water
temperature for your home.
Safety Precautions
Disconnect all power to water
heater if it has been subjected to
over heating, fire, flood, physical
damage.
DO NOT turn on water heater
unless it is filled with water.
DO NOT turn on water heater if
cold water supply shut-off valve
is closed.
If there is any difficulty in
understanding or following the
Operating Instructions or the
Care and Cleaning section, it is
recommended that a qualified
person or serviceman perform the
work.
CAUTION: Hydrogen gas can be produced in a hot water system served by this water heater that has not
been used for a long period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY
FLAMMABLE!! To dissipate such gas and to reduce risk of injury, it is recommended that the hot water faucet
be opened for several minutes at the kitchen sink before using any electrical appliance connected to the hot water
system. If hydrogen is present, there will be an unusual sound such as air escaping through the pipe as the water
begins to flow. DO NOT smoke or use an open flame near the faucet at the time it is open.
Safety Controls
WARNING: If the water
heater has been subjected
to fire, flood or physical
damage, disconnect all
power to water heater, and
DO NOT operate the water
heater again until it has
been checked by a qualified
service technician.
NOTICE: DO NOT use
this appliance if any
part has been under
water. Immediately call

Care and cleaning of the water heater
Routine Preventative Maintenance
Properly maintained, your water heater
will provide years of dependable
trouble-free service.
It is suggested that a routine preventive
maintenance program be established
and followed by the user.
Most electrical appliances, even
when new, make some sound when
in operation. If the hissing or singing
sound level increases excessively,
Contact a qualified installer or
plumbing contractor to inspect.
IMPORTANT: See "DANGER
on left". At least once a year, lift
and release the lever handle on the
temperature pressure relief valve,
located on the side of the water heater,
to make certain the valve operates
freely. Allow several gallons to flush
through the discharge line to an open
drain.
It is recommended to clean the filter
on top of the heat pump when "Clean
filter reminder" alert appears. Clean by
washing with mild detergent and water.
Dry and replace. Remove the filter by
lifting up, then replace by lowering
back into the filter slot on top of the
unit. See Figure below.
At least once a year pour a cup of
bleach in the access opening of the
condensate drain to kill any algae,
mold, or mildew that has formed in the
pipe. Ensure the condensate can flow
freely; unclog if needed.
A water heater’s tank can act as a
setting basin for solids suspended in the
water. It is therefore not uncommon for
hard water deposits to accumulate in the
bottom of the tank. It is suggested that a
few quarts of water be drained from the
water heater’s tank every month to clean
the tank of these deposits.
Rapid closing of faucets or solenoid
valves in automatic water using
appliances can cause a banging noise
heard in a water pipe. Strategically
located risers in the water pipe system
or water hammer arresting devices can
be used to minimize the problem.
DANGER: Before
manually operating the
relief valve, make certain
no one will be exposed to
the danger of coming in
contact with the hot water
released by the valve. The
water may be hot enough
to create a scald hazard.
The water should be
released into a suitable
drain to prevent injury or
property damage.
NOTICE: If the
temperature and pressure
relief valve on the
water heater discharges
periodically, this may be
due to thermal expansion
in a closed water system.
Contact the water
supplier or your plumbing
contractor on how to
correct this. DO NOT
plug the relief valve outlet.
Draining the Water Heater
CAUTION: Shut off power to the
water heater before draining water.
DANGER: Before manually
operating the relief valve, make
certain no one will be exposed to the
hot water released by the valve. The
water drained from the tank may be
hot enough to present a scald hazard
and should be directed to a suitable
drain to prevent injury or damage.
In order to drain the water heater, turn
off the cold water supply. Open a hot
water faucet or lift the handle on the
relief valve to admit air to the tank.
Attach a garden hose to the drain valve
on the water heater and direct the
stream of water to a drain. Open the
valve.

Care and cleaning of the water heater
Vacation and Extended Shut-Down
If the water heater is to remain idle for an
extended period of time, the power and
water to the appliance should be turned
off to conserve energy and prevent a
build-up of dangerous hydrogen gas.
The water heater and piping should be
drained if they might be subjected to
freezing temperatures.
After a long shut-down period, the
water heater’s operation and controls
should be checked by qualified service
personnel. Make certain the water heater
is completely filled again before placing
it in operation.
NOTICE: Refer to the
Hydrogen Gas Caution in
the Operating Instructions.
Anode Rod
This water heater is equipped with an
anode rod designed to prolong the life
of the glass-lined tank. The anode rod is
slowly consumed, thereby eliminating
or minimizing corrosion of the glass-
lined tank.
Water sometimes contains a high sulfate
and/or mineral content and together with
cathodic protection process can produce
a hydrogen sulfide, or rotten egg odor
in the heated water. Chlorination of
the water supply should minimize the
problem.
NOTICE: DO NOT
remove the anode rod
from the water heater’s
tank. Operation with the
anode rod removed will
greatly shorten the life of
the glass lined tank and
will exclude warranty
coverage.

Code Troubleshoong Guide Possible Causes What to Do
A004 Comp.Shutdown: Discharge-Sucon Trip
Heang source defaults to
elements due to compressor
malfuncon
1. Conrm fan is operaonal while
compressor is on. (If the fan is not
operaonal, check connuity from
middle(ground)terminal to either
outside terminal. If there is a 60V or
higher reading, the fan should be run-
ning and will need to be replaced. If
not, replace the control board (rare)).
2. Conrm lter screen is clean.
3. Inspect compressor and surrounding
components for any obvious signs of
refrigerant leak (oily residue) If the
compressor is not operaonal or there
are signs of leakage, the unit will need
to be replaced as we do not service
sealed system parts.
