SECTION II: GENERAL INFORMATION
SUN BANDITВ® HYBRID WATER HEATER FUNCTION
The Sun BanditВ® Hybrid Water Heater is designed to heat water with electric resistance
heating elements that are powered from two different sources, 1) electricity generated by the
Sun BanditВ® AC Micro-Grid (i.e. PV modules plus Sun BanditВ® AC Micro-Grid Inverter) and
2) standard utility power. Sun BanditВ® AC Micro-Grid resistive elements are located in the
tank such that all stored water could be heated from solar energy. A standard utility powered
element is located to ensure 50% of the stored water is always heated.
All models include three Sun BanditВ® AC Micro-Grid Resistive Elements. The Sun BanditВ®
Upper/Lower AC Micro-Grid Resistive Elements are wired in the same circuit for nonsimultaneous operation (i.e. either Upper or Lower element is energized). For simultaneous
operation of AC Micro-Grid Resistive Elements, a separate Sun BanditВ® Single AC Micro-Grid
Resistive Element is available for use. The Single AC Micro-Grid Resistive Element is wired
on an independent circuit and operates autonomously from the Sun BanditВ® Upper/Lower AC
Micro-Grid Resistive Elements.
Power availability from the Sun BanditВ® AC Micro-Grid will vary depending on outside
conditions.
WATER TREATMENT & FILTRATION
In areas where poor water conditions are suspected (i.e. lime, iron, and other minerals), it
is essential that the water be tested and appropriate action taken to prevent damage to the
water heater and ensure the quality of the water.
Page 5
SECTION II: GENERAL INFORMATION (cont.)
TEMPERATURE CONTROL
The Sun BanditВ® Hybrid Water Heater is equipped with resistive elements and adjustable
thermostats. If the solar system cannot satisfy the user demand, the standard utility powered
resistive element will energize and heat the water until its 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 180В°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 180В°F.
The Sun BanditВ® AC Micro-Grid Resistive Element thermostats are factory set to 120В°F. The
standard utility power thermostat is also factory set to 120В°F. See Table 6 for thermostat letter
and temperature relationships. Setting the temperature on the AC Micro-Grid thermostats
higher than the standard utility power thermostat will allow the system to maximize water
heating from solar energy.
THE THERMOSTATIC MIXING VALVE THAT IS SUPPLIED WITH THIS WATER
HEATER MUST BE INSTALLED PER THE VALVE MANUFACTURER’S INSTRUCTIONS.
Water temperatures in the tank will exceed 120В°F. The supplied mixing valve must be
installed to the Sun BanditВ® Hybrid Water Heater and adjusted to a safe temperature. The
recommended water temperature for normal residential use is 120В°F. Table 3 details the
approximate relationship of water temperature and time with regard to scald injury. Measure
water temperature at the tap nearest to the water heater and adjust the mixing valve
according to the valve manufacturer’s instructions.

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 will 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.
CAUTION
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 120В°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 water 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.
Page 7
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.
IF YOU SMELL GAS:
• DO NOT try to light any appliance.
• DO NOT touch any electric switch; do not use any telephone in your building.
• Immediately call your gas supplier from a telephone in another building. Follow your
gas supplier’s instructions.
• If you cannot reach your gas supplier, call the fire department.
DO NOT OPERATE THE APPLIANCE UNTIL THE LEAKAGE IS CORRECTED!
CAUTION
Do not drop water heater or lay heater down on its side. Move the water heater into
position by sliding or using an appropriately sized hand truck.
The Sun BanditВ® Hybrid Water Heater must be installed indoors. Locate the water heater as
close as practical to the Sun BanditВ® AC Micro-Grid system and leave sufficient clearances for

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 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 on
all models. 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 the supplied thermostatic mixing valve to the “Cold”
and “Hot” connections on the top of the water heater. Follow the instructions that are
supplied with the mixing valve.
2) Install a union and shut-off valve on both the cold and hot water sides of the water heater.
3) 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.
4) 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.

SECTION V: OPERATION
THERMOSTAT TEMPERATURE ADJUSTMENT
CAUTION
The temperature setting on the heating element thermostat shall not exceed 160В°F.
The thermostatic mixing valve supplied with this water heater must be installed to
reduce the risk of scalding.
CAUTION
Turn off all power to the water heater before adjusting the heating element thermostat.
All thermostats are factory adjusted to 120°F (“HOT” indicator setting). If thermostat
adjustment is necessary, disconnect all power to the water heater. 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.

CAUTION
Hot water in excess of 120В°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 thermostatic 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 mixed water temperature. Adjust the thermostat or
mixing valve setting as necessary. Adjusting the thermostat or mixing valve setting 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.
Page 14
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. U
se 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.
8. Snap caps back into place.
FLUSH THE TANK
The Sun BanditВ® Hybrid Water Heater is glass lined. Elements in the water such as lime,
iron and other minerals may accumulate in the heater. It is recommended that the tank be
drained and flushed thoroughly once a year to prevent buildup in the tank.
MIXING VALVE
The thermostatic mixing valve should be checked annually to ensure proper operation. Refer
to the installation instructions for the manufacturer’s recommended maintenance procedure.
