WARNING
Improper installation, adjustment, alteration,
service or maintenance can cause serious
injury or property damage. Refer to this
manual. For assistance or additional
information, consult a qualified installer or
service agency.
CAUTION
The recommended temperature for normal
residential use is 120°F. The dial on the
aquastat does not always reflect the out-
coming water temperature, which could
occasionally exceed 120°F. The variation in
out-coming temperature could be based on
factors including but not limited to usage
patterns and type of installation. Test your
water at the tap nearest to the water heater.
WARNING
Hotter water increases the risk of scald injury.
Before adjusting the water temperature setting,
read this instruction manual. Temperatures at
which injury occurs vary with the person’s age
and the length of exposure.
The slower reaction time of children, elderly,
and physically or mentally challenged persons
increases the scalding hazard to them. It is
recommended that lower water temperatures
be used where these exposure hazards exist.
Such households may require a temperature
setting less than 120°F to prevent accidental
contact with hot water.
To lower water temperature use point-of-use
temperature limiting devices.
WARNING
Water heater blankets are not recommended
and will void the warranty.

SECTION II: GENERAL INFORMATION
SOLAR WATER HEATER FUNCTION
The solar water heater is designed with an internal coil and backup electric heating element.
In lieu of an electric heating element, some models incorporate a second internal coil for
backup heating. Furthermore, 2 Coil models are designed with a second internal coil and an
electric heating element. A heating medium is passed through the solar panels and internal
coil as long as there is an adequate temperature difference between the heating medium and
stored water in the tank. The internal coil is located as close to the bottom as possible to
facilitate the transfer of heat even at lower solar panel temperatures.
During periods of water flow through the water heater, hot water is drawn from the top of
the heater and cold water is delivered to the bottom of the tank (by a diptube or bottom
inlet). If the hot water demand should exceed the solar heat output or there is an insufficient
temperature difference between the heating medium and stored water, the heating element
thermostat will activate the electrical heating element for backup heat. When an additional
internal coil is used for backup heating, an aquastat should be used for flow control in the
backup heating loop. An aquastat immersion well is supplied on 2 Coil and 2 Coil models.
Solar heat output from the internal coil will vary depending on outside conditions and the
temperature of the stored water.

SECTION II: GENERAL INFORMATION (cont.)
TEMPERATURE CONTROL
A solar controller (not provided) shall be used in conjunction with the solar water heater to
run all solar components in the heating system. The solar controller will be connected to
two thermistors that monitor lower and upper tank temperature. In some cases, only one
thermistor (near the bottom of the tank) will be used. The proper temperature setting for
domestic hot water use is 120°F/49°C.
The solar water heater is equipped with a backup electrical heating element and adjustable
thermostat. The thermostat is located behind the access cover on the side of the water heater.
If the solar system cannot satisfy the user demand, the electric element will energize and heat
the water until the thermostat is satisfied. An ECO (electrical cut-off) is included as part of
the temperature control and is designed to cut off power to the heating element in the event
the water in the tank reaches 180°F. The ECO is a safety feature on the water heater and
cannot be adjusted. In the event that the ECO opens, the control must be manually reset with
the stored water temperature below 180°F.
The thermostat is factory set at 120°F. See Table 6 for thermostat letter and temperature
relationships. If hotter water is required a tempering device or anti-scald device must be
installed at the domestic hot water outlet of the heater or at the point of use. Table 3 details
the approximate relationship of water temperature and time with regard to scald injury. It
is important for the user to understand the necessity of tempering or anti-scald devices when
using hotter water in domestic water heating systems.
CAUTION: Hot water in excess of 120°F can cause scalding!
Rheem recommends a tempering valve or anti-scald valve be installed and used according
to the manufacturer’s directions to prevent scalding. Many state and local codes now require
installation of these devices. The tempering valve or anti-scald valve will ensure potable
water temperatures at the desired set point with a higher degree of accuracy.

SECTION II: GENERAL INFORMATION (cont.)
ANODE RODS
The anode rod is used as a sacrificial element within the volume of the storage tank. The
purpose of the magnesium anode rod is to protect the inside of the tank against corrosion.
Anode rods should be inspected twice in the first year and at least yearly once a time interval
for inspection has been developed. Water conditions can influence the consumption rate of
the anode rods. Please see the Maintenance section of this manual for instructions on how to
change the anode rods in your water heater.
Hydrogen gas is produced in a hot water system served by the heater that has not
been used for a long period of time (2 weeks or more). Hydrogen gas is extremely
flammable. To reduce the risk of injury under these conditions, 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. When hydrogen
is present, there will probably be an unusual sound such as air escaping through the
pipe as the water begins to flow. There should be no smoking or open flame near the
faucet at the time it is open.
TEMPERATURE AND PRESSURE RELIEF VALVE (T&P)
CAUTION
To reduce the risk of excessive pressures and temperatures in this water heater, install
temperature and pressure protective equipment required by local codes and no less
than a combination temperature and pressure relief valve certified by a nationally
recognized testing laboratory that maintains periodic inspection of production of listed
equipment or materials, as meeting the requirements for Relief Valves and Automatic
Gas Shutoff Devices for Hot Water Supply Systems, ANSI Z21.22. This valve must be
marked with a maximum set pressure not to exceed the marked maximum working
pressure of the water heater. Install the valve in an opening provided and marked for
this purpose in the water heater, and orient it or provide tubing so that any discharge
from the valve exits only within 6 inches above, or at any distance below, the
structural floor, and does not contact any live electrical part. The discharge opening
must not be blocked or reduced in size under any circumstances.
The T&P valve is factory installed. A discharge drain tube must be installed (responsibility
of the installer) and shall terminate plain, not threaded, 6 inches above the floor drain.
The drain tube material must be approved for temperatures of 120°F or greater and a
pressure of 150 PSI or greater.
BACKFLOW PREVENTER (CLOSED LOOP SYSTEM)
Some local municipal codes and ordinances require the use of these devices on potable
(domestic) water lines. Where backflow preventers are required, it will be necessary to install
a thermal expansion tank (designed for used with potable water) in order to prevent
pressure build up in the indirect heater and associated piping, which could cause the T&P
valve to discharge. Follow the expansion tank manufacturer’s recommendations when
selecting a tank for your hot water system.
Note: Working pressure of the water heater is 150 PSI. Do not exceed 150 PSI.

SECTION III: PRE-INSTALLATION
LOCATION
CAUTION
This water heater must be located in an area where leakage of the tank, water line
connections, or the temperature and pressure relief valve will not result in damage to
the area adjacent to the water heater or to lower floors of the structure. When such
location cannot be avoided, a suitable drain pan must be installed under the water
heater. The drain pan depth must be suitable for draining and collecting water. The
drain pan can be purchased from your plumbing professional. The drain pan must
be piped to an adequate drain and all drain piping must be at least 0.75” in diameter
and pitched for proper drainage.
CAUTION
DO NOT store or use gasoline or other flammable, combustible, or corrosive vapors
and/or liquids in the vicinity of the water heater or any other appliance.

SECTION IV: INSTALLATION
WATER CONNECTIONS
CAUTION
This water heater incorporates fittings that contain a nonmetallic lining. DO NOT apply
heat to these fittings when making sweat connections to the heater. Sweat tubing to
an adapter before securing adapter to any fittings on water heaters.
ALL PIPING SHOULD CONFORM TO LOCAL CODES AND ORDINANCES. It is highly
recommended that unions and shut-off valves are installed at the potable water and heat
exchanger connections to allow for isolation and/or movement during service. Installing a
union on the potable outlet is of particular importance to facilitate replacement of the hot
outlet/anode nipple. In addition, all piping should be adequately insulated with an approved
material to minimize heat loss.
POTABLE WATER CONNECTIONS
THE WATER HEATER MUST BE FILLED WITH WATER BEFORE CONNECTING
ELECTRIC POWER.
1) Close the main water supply valve before continuing with the installation. After the
main water supply is shut-off, relieve the water line pressure by opening a faucet. Once the
pressure has been relieved, close the faucet. The “Cold” and “Hot” potable water connections
are labeled on the water heater. Install a union and shut-off valve at both potable water
connections. All piping should be 3/4” diameter new copper or larger. A tempering valve
or anti-scald valve should be installed at the potable water outlet and used according to the
manufacturer’s specifications to prevent scalding.
2) If a backflow preventer is required in the cold water supply, a properly sized expansion
tank must be installed to control thermal expansion. Do not operate the water heater in
a closed system without installing a thermal expansion tank. Follow the expansion tank
manufacturer’s recommendations when selecting a tank for your system.
3) Following installation of the water lines, open the main water supply valve and fill the
water heater. Open several hot water faucets to relieve air from the system. After water is
flowing through the faucets and the system is void of air, close the faucets and check for
water leaks in the system.
SOLAR CONNECTIONS
CAUTION
Temperature of the primary heat source medium (from solar collector or boiler) shall
not exceed 200°F.
The outlet of the solar collector should be connected to the water heater at the “FROM SOLAR”
fitting. The fitting labeled “TO SOLAR” should be connected to the solar return piping. It
is recommended to install a union and shut-off valve at each solar connection. All pipe and
fittings between the solar system and water heater should be 3/4” diameter or larger.

ELECTRICAL CONNECTIONS
DANGER
Confirm that all electrical connections are unpowered before installing or servicing
electrical components/connections within the water heater.
WARNING
The water heater must be electrically grounded in accordance with local codes or, in
the absence of local codes, with NFPA 70.
Failure to properly wire electrical connections may result in serious physical harm.
Electrical power may be from more than one source. Make sure all power is off before
attempting any electrical work.
ELECTRIC HEATING ELEMENT (BACKUP)
THE WATER HEATER MUST BE FILLED
WITH WATER BEFORE CONNECTING
ELECTRIC POWER.
All electrical connections on the water heater
must be made with copper conductors only. A
separate branch circuit with copper conductors,
over-current protection, and means for
disconnection must be provided by qualified
service personnel. The total wattage load and
voltage requirements for the water heater are
specified on the rating label located on the front
of the heater.
The thermostat and electric heating element
are pre-wired at the factory. A junction box
is located at the top of the water heater. The
junction box cover will accommodate a 1/2” or
3/4” electrical conduit connector. Two wires
are located in the junction box (red and black)
for connection to the branch circuit. See Figure
6 for a wiring diagram.
GROUNDING INSTRUCTIONS
A green screw (ground) is located in the junction box for proper connection to ground from
the branch circuit.
SOLAR CONTROLLER AND THERMISTORS
Two locations for potable water temperature measurement have been provided. The factory
installed immersion wells are designed to accommodate insertion of a thermistor. The solar

SECTION V: OPERATION
INITIAL START-UP
Reference the solar collector installation instructions for proper start-up of the solar collector.
Be sure that fluid flow in the solar system is established.
HEATING OPERATIONS
Condition 1: The minimum temperature difference (for heat transfer) between the potable
water at the bottom of the tank and the solar collector is sensed by the solar controller. In
addition, the tank temperature is below the maximum tank temperature setpoint (on solar
control).
Action 1: The solar controller energizes a pump to flow fluid through the solar
collector and heat exchanger. Heat is transferred to the potable water until
the temperature difference is reduced to a desired value or the maximum tank
temperature has been reached.
Condition 2: The heating element thermostat senses that the potable water temperature in
the upper area of the tank drops below the thermostat set-point.
Action 2: The heating element is energized and heats the potable water to the set-
point temperature, at which point the element is de-energized.
THERMOSTAT TEMPERATURE ADJUSTMENT
CAUTION
The temperature setting on the heating element thermostat shall not exceed 160°F.
Likewise, the solar controller potable water temperature setting shall not exceed 160°F.
Install a tempering valve or anti-scald mixing valve at the outlet of the water heater to
ensure greater control over water temperatures at the point of use.
CAUTION
Turn off all power to the water heater before adjusting the heating element thermostat.
The heating element thermostat is factory adjusted to 120°F (“HOT” indicator setting). If
thermostat adjustment is necessary, disconnect all power to the water heater and solar
collector. Remove the access cover on the side of the water heater and remove the foam dam
insert to expose the thermostat and heating element. The temperature knob can be adjusted
with a screwdriver to a minimum temperature of 110°F and a maximum temperature of
160°F (labeled “VERY HOT”). See Table 6 for a listing of indicator setting and temperature
relationships.

Page 15
CAUTION
Hot water in excess of 120°F can cause scalding! The temperature at which injury
occurs varies with the person’s age and the time of exposure. The slower response
time of disabled persons increases the hazards to them. NEVER allow small children to
use a hot water tap. NEVER leave a child or disabled person unattended in a bathtub
or shower.
Replace the foam dam insert and access cover after adjusting/inspecting the thermostat.
If the thermostat temperature setting (or anti-scald mixing valve) was adjusted, check
the water temperature at a faucet. Flow enough water through the faucet to ensure that
the faucet temperature reflects the tank temperature. Adjust the thermostat or mixing
valve setting as necessary. Adjusting the thermostat setting (lower or higher) will not
immediately affect the water temperature at the faucet. Flow a sufficient amount of water
or allow a heat-up cycle to complete before making further adjustments.
SECTION VI: MAINTENANCE
WATER PIPING
On an annual basis, all piping should be checked for leakage at joints, shut-off valves, and
unions.
T&P RELIEF VALVE
On an annual basis, the temperature and pressure relief valve should be checked for proper
operation. First, attach a drain line to the valve to direct the water discharge to an open
drain. This is very important because the temperature of the discharge could be very hot.
Second, lift the lever at the end of the valve several times. The valve should operate freely
and return to its original position properly. If water does not flow out of the valve, remove
and inspect for corrosion or obstructions. Replace with a new valve if necessary. Do not
repair the faulty valve as this may cause improper operation.
ANODE RODS
Anode rods should be inspected twice in the first year and at least yearly once a time interval
for inspection has been developed. It is recommended to check the rod(s) six months after
the heater is installed. If the anode rod had reduced in size by two-thirds of its original
diameter of 3/4” or shows signs of pitting, it is time for replacement. Take the following
steps when changing the anode rod(s):
1. Shut off water supply.
2. Open any faucet to relieve tank pressure.
3. Remove caps on water heater top; push insulation aside.
4. Use a 1 1/16” six-sided socket wrench and a breaker bar. Snap hard to break the anode
rod seal.
5. Remove rod(s) and replace with new rod(s).
6. Turn water supply back on and leave faucet open until air is out of line.
7. Turn faucet off and check that new rod(s) doesn’t leak.
SECTION V: OPERATION (cont.)
8. Snap caps back into place.
