IMPORTANT SAFETY INFORMATION  
Read the following important safety information before using this equipment to avoid serious injury or death  
and to avoid damage to equipment or property.  
WARNING  
WARNING  
ELECTRIC SHOCK HAZARD:  
FOR INSTALLING COMBINATION TEMPERATURE/  
PRESSURE RELIEF VALVES IN ACCORDANCE WITH  
AMERICAN NATIONAL STD. Z21.22-1979. Combination  
temperature/pressure relief valves with extension  
thermostats must be installed so that the temperature-  
sensing element is immersed in the water within the top 6"  
(152 mm) of the tank. They must be installed either in the  
hot outlet service line or directly in a tank tapping.  
Combination temperature/pressure relief valves that do  
not have extension elements must be mounted directly in  
a tank tapping located within the top 6" (152 mm) of the  
tank, and shall be adequately insulated and located so as  
to assure isolation from the flue gas heat or other ambient  
conditions that are not indicative of stored water  
temperature. TO AVOID WATER DAMAGE OR SCALDING  
DUE TO VALVE OPERATION, DRAIN PIPE MUST BE  
CONNECTED TO VALVE OUTLET AND RUN TO A SAFE  
PLACE OF DISPOSAL. Discharge line must be as short as  
possible and be the same size as the valve discharge  
connection throughout its entire length. Drain line must  
pitch downward from the valve and must terminate  
between 1-1/2" (38 mm) and 6" (152 mm) above the floor  
drain where any discharge will be clearly visible. The drain  
line shall terminate plain, not threaded, with material  
serviceable for temperatures up to 250°F (121°C) or  
greater. Excessive length, over 30' (9144 mm), or use of  
more than four elbows can cause a restriction and reduce  
the discharge capacity of the valve. No shut-off valve shall  
be installed between the relief valve and tank, or in the  
drain line. Valve lever must be tripped periodically to  
assure that waterways are clear. This device is designated  
for emergency safety relief and shall not be used as an  
operating control. The valves are set to relieve at 150 psi  
(1034 kPa) or when water temperature reaches 210°F  
(99°C). Read tag on valve for additional information.  
• This unit must be installed by qualified, trained  
installers. Installation must conform to all local  
electrical and plumbing codes. Check with your local  
plumbing and electrical inspectors for proper  
procedures and codes.  
• Turn power OFF at disconnect switch/circuit breaker  
and allow unit to cool before performing any  
maintenance or cleaning.  
• Consult a licensed electrical contractor for proper  
electrical installation conforming to local electrical  
codes and the National Electrical Code (N.E.C.).  
• Unit is not weatherproof. Locate unit indoors where  
ambient air temperature is a minimum of 70°F (21°C).  
• Do not place aftermarket covers on or over booster  
water heater. Doing so can cause temperature and  
moisture build-up resulting in premature failure and  
electrical shock.  
• This unit must be serviced by qualified personnel only.  
Service by unqualified personnel may lead to electric  
shock or burn.  
• Use only Genuine Bradford White Replacement Parts  
when service is required. Failure to use Genuine Bradford  
White Replacement Parts will void all warranties and may  
subject operators of the equipment to hazardous  
electrical voltage, resulting in electrical shock or burn.  
Genuine Bradford White Replacement Parts are specified  
to operate safely in the environments in which they are  
used. Some aftermarket or generic replacement parts do  
not have the characteristics that will allow them to operate  
safely in Bradford White equipment.  
EXPLOSION HAZARD: Do not store or use gasoline or  
other flammable vapors or liquids in the vicinity of this or  
any other appliance.  
Inspect combination temperature/pressure relief valve at  
least once every two to four years, depending on local  
water conditions. Contact a licensed plumber or qualified  
service technician for inspection. Replace valve, if  
necessary. DO NOT attempt to self-inspect valve.  
Bradford White has always endorsed the use of safety  
equipment when using an booster water heater or storage-  
type water heater. Bradford White booster water heaters  
are shipped with a temperature/pressure relief valve at no  
extra charge. This valve must be installed into the marked  
opening provided in the tank. Valves supplied with this  
booster water heater are designed for high temperature  
commercial operation. Do not substitute these valves with  
valves designed for domestic water heaters.  
Use only plumbing material suitable for a minimum water  
temperature of 200°F (93°C). Materials used must meet  
National Sanitation Foundation (NSF) specifications and  
all local plumbing codes and regulations.  
Install booster water heater in horizontal position with  
base parallel to the floor and inlet connection at the lowest  
point. If installing with legs, mount on floor. If installing  
with slide brackets, mount under dish table. DO NOT  
mount on walls or in ceiling. Unit must be accessible for  
service. Improper installation could create an unsafe  
condition.  
Temperature/pressure protective equipment should not be  
less than a combination temperature/pressure relief valve  
certified by a nationally recognized testing laboratory that  
maintains periodic inspection of the production of this  
equipment and meets the requirements for Relief Valves  
and Automatic Shutoff Devices for Hot Water Supply  
Systems, ANSI Z21.22-1979. The temperature/pressure  
relief valve must be marked with a minimum set pressure  
not to exceed the marked hydrostatic test pressure of the  
booster heater as noted on the unit specifications.  
Valves supplied with this booster water heater are  
designed for high temperature commercial operation. Do  
not substitute these valves with valves designed for  
domestic water heaters.  
Do not connect an expansion tank of any type to booster  
water heater lines.

IMPORTANT SAFETY INFORMATION  
Read the following important safety information before using this equipment to avoid serious injury or death  
and to avoid damage to equipment or property.  
WARNING  
Units are equipped with a high temperature limit safety  
switch that will shut off power if the unit overheats.  
Contact an Authorized Service Agent if high temperature  
limit safety switch cannot be reset or continues to trip.  
Do not store any materials or items on or against the  
housing of the booster water heater.  
Bradford White requires that two temperature/pressure  
gauges be installed to assure proper operation. Install one  
in the supply line before the pressure reducing valve and  
one in the outlet line as close to the booster water heater  
as possible. This provides a visual check of the water  
temperature and pressure before and after the water  
heater.  
Install booster water heater as close as possible to the  
commercial dish machine. Employ recirculation if  
distance between booster and commercial dish machine  
exceeds National Sanitation Foundation (NSF)  
specifications of five (5) linear feet (1524 mm).  
Make sure the dish table is strong enough to support the  
weight of the booster heater and water when installing  
with slide mounting brackets.  
If water supply pressure to the booster water heater inlet  
is over 20 psi (138 kPa) during flow, install a commercial-  
grade pressure reducing valve with built-in bypass for  
proper operation of dish machine rinse nozzles.  
Follow standard welding safety and operational  
procedures when attaching sliderails to bottom of dish  
table.  
NOTE: The pressure reducing valve must be the type  
equipped with a high pressure bypass, like the valve  
supplied with this booster water heater.  
This product contains fiberglass, a product known to the  
state of California to cause cancer, birth defects or other  
reproductive harm.  
NOTICE  
DO NOT turn on power to the booster water heater until  
tank has been filled with water and all air has been vented  
through dish machine rinse nozzle. The heating elements  
will burn out in seconds if operated when they are not  
immersed in water.  
It is essential to recognize that even though a booster  
water heater may be installed properly and approved  
initially, there always exists the possibility that unknowing  
individuals might alter or change the installation in a  
manner that would render it unsafe. Therefore, it is  
important that all safety programs provide some  
mechanism to assure that these installations are  
inspected periodically.  
ALWAYS drain booster water heater with power to the unit  
off or element burnout could occur.  
Use dielectric couplings when connecting dissimilar  
metals, such as galvanized to copper. This will prevent  
electrolysis or premature plumbing damage.  
This unit has no “user-serviceable” parts. If service is  
required on this unit, contact an Authorized Service Agent  
or the Bradford White Service Department.  
DO NOT turn or adjust inlet water connection on Magnum  
Series booster water heaters. Doing so will change the  
internal water flow.  
CAUTION  
BURN HAZARD:  
Do not back out or loosen any pipe fittings. Doing so may  
cause leaks.  
• Water in unit is very hot. Wear protective gloves and  
proper attire when operating to avoid injury.  
Do not lay unit on the side with the control panel. Damage  
to the unit could occur.  
• Some exterior surfaces on unit will get hot. Avoid  
unnecessary contact with unit.  
Incoming water in excess of 3 grains of hardness per  
gallon (GPG) (0.75 grains of hardness per liter [GPL]) must  
be treated and softened before being supplied to booster  
heater(s). Water containing over 3 GPG (0.75 GPL) will  
decrease efficiency, increase energy use, and reduce the  
operating life of the unit through increased lime build-up.  
Product failure caused by liming or sediment buildup is  
not covered under warranty.  
• Valves supplied with this booster water heater are  
designed for high temperature commercial operation.  
Do not substitute these valves with valves designed for  
domestic water heaters.  
Do not use anti-siphon or check valves on incoming water  
line.  
Do not connect booster water heater directly to a boiler or  
furnace coil or any other uncontrolled temperature  
source. The booster heater thermostat could be damaged  
causing unit to overheat.  
Do not use deionized or reverse osmosis (R.O.) treated  
water in booster water heaters. Damage to booster heater  
may occur.  
Do not connect booster water heater to domestic  
(consumer) dishwashers or other domestic utilized  
equipment. Hot water from booster heater may damage  
domestic equipment resulting in a hazardous condition.  
Connect electric booster water heater to the same power  
supply as indicated on the specification decal only.  
Connecting unit to an incorrect power supply voids the  
product warranty and will damage the equipment.

INSTALLATION  
Temperature/Pressure Relief Valves  
Pressure Reducing Valve  
CAUTION  
If water supply pressure to the booster water heater inlet  
is over 20 psi (138 kPa) during flow, install a commercial-  
grade pressure reducing valve with built-in bypass for  
proper operation of dish machine rinse nozzles.  
For protection against excessive pressures and temperatures in  
the booster heater, install temperature/pressure protective  
equipment required by local codes. The temperature/pressure  
relief valve supplied with this booster water heater is  
constructed with brass working parts and heat resistant silicone  
seat discs.  
NOTE: The pressure reducing valve must be the type  
equipped with a high pressure bypass like the valve  
supplied with this booster water heater.  
WARNING  
Temperature/pressure protective equipment should not be  
less than a combination temperature/pressure relief valve  
certified by a nationally recognized testing laboratory that  
maintains periodic inspection of the production of this  
equipment and meets the requirements for Relief Valves  
and Automatic Shutoff Devices for Hot Water Supply  
Systems, ANSI Z21.22-1979. The temperature/pressure  
relief valve must be marked with a minimum set pressure  
not to exceed the marked hydrostatic test pressure of the  
booster heater as noted on the unit specifications.  
Proper operation of the commercial dish machine rinse nozzles  
requires that available water pressure at the rinse nozzle be  
between 15 and 25 psi (103 and 172 kPa) when the nozzle is  
operated. 20 psi (138 kPa) is recommended. If water pressure  
available to the booster water heater inlet is over 20 psi  
(138 kPa), a pressure reducing valve must be installed in the hot  
water supply line to the booster water heater and adjusted to  
deliver 20 psi (138 kPa) flow pressure.  
The valve supplied with the unit has a built-in high pressure  
bypass that prevents excessive pressure build-up as the  
booster heats up. Final adjustment is required at the time of  
installation.  
FOR INSTALLING COMBINATION TEMPERATURE/  
PRESSURE RELIEF VALVES IN ACCORDANCE WITH  
AMERICAN NATIONAL STD. Z21.22-1979. Combination  
temperature/pressure relief valves with extension  
thermostats must be installed so that the temperature-  
sensing element is immersed in the water within the top 6"  
(152 mm) of the tank. They must be installed either in the  
hot outlet service line or directly in a tank tapping.  
Combination temperature/pressure relief valves that do  
not have extension elements must be mounted directly in  
a tank tapping located within the top 6" (152 mm) of the  
tank, and shall be adequately insulated and located so as  
to assure isolation from the flue gas heat or other ambient  
conditions that are not indicative of stored water  
temperature. TO AVOID WATER DAMAGE OR SCALDING  
DUE TO VALVE OPERATION, DRAIN PIPE MUST BE  
CONNECTED TO VALVE OUTLET AND RUN TO A SAFE  
PLACE OF DISPOSAL. Discharge line must be as short as  
possible and be the same size as the valve discharge  
connection throughout its entire length. Drain line must  
pitch downward from the valve and must terminate  
between 1-1/2" (38 mm) and 6" (152 mm) above the floor  
drain where any discharge will be clearly visible. The drain  
line shall terminate plain, not threaded, with material  
serviceable for temperatures up to 250°F (121°C) or  
greater. Excessive length, over 30' (9144 mm), or use of  
more than four elbows can cause a restriction and reduce  
the discharge capacity of the valve. No shut-off valve shall  
be installed between the relief valve and tank, or in the  
drain line. Valve lever must be tripped periodically to  
assure that waterways are clear. This device is designated  
for emergency safety relief and shall not be used as an  
operating control. The valves are set to relieve at 150 psi  
(1034 kPa) or when water temperature reaches 210°F  
(99°C). Read tag on valve for additional information.  
Temperature/Pressure Gauges  
CAUTION  
Bradford White requires that two temperature/pressure  
gauges be installed to assure proper operation. Install one  
in the supply line before the pressure reducing valve and  
one in the outlet line as close to the booster water heater  
as possible. This provides a visual check of the water  
temperature and pressure before and after the water  
heater.  
NOTE: If a check valve is installed and cannot be removed  
install a back pressure relief valve set at 125 psi (862  
kPa) on the incoming line between the pressure  
reducing valve and the inlet to the booster water  
heater. Discharge must be to open site drain (see  
Figure 7).  
Blended Phosphate Water Treatment  
System (optional)  
Bradford White recommends that the Blended Phosphate Water  
Treatment System be installed with unions on the incoming 3/4"  
water supply line after the pressure reducing valve and before  
the booster water heater.  
Cartridges supplied have a usage rating of 100,000 gallons  
(378,541 liters) of water. To assure proper operation the  
cartridges must be replaced when expired.  
NOTE: Product failure caused by liming or sediment buildup is  
not covered under warranty.  
CAUTION  
BURN HAZARD: Valves supplied with this booster water  
heater are designed for high temperature commercial  
operation. Do not substitute these valves with valves  
designed for domestic water heaters.  
Do not use an anti-siphon or check valves on incoming  
water line.

INSTALLATION  
Inlet  
Plumbing Connections  
(Refer to Figure 5, 6, or 7)  
Use the following procedures to connect the inlet and outlet  
water lines as well as inspect the system once the plumbing  
connections are complete.  
1. Connect the booster water heater inlet to a hot water  
supply line from the regular water heater. Water  
temperature from the regular water heater should be 110°  
or 140°F (43° or 60°C) and should not exceed 160°F  
(71°C). Minimum temperature differential between inlet and  
outlet should never be less than 20°F (11°C).  
WARNING  
Do not connect an expansion tank of any type to booster  
water heater lines.  
NOTE: The red mark on the inlet and outlet water pipes of  
Magnum Series units must remain in the top most  
position.  
Use only plumbing material suitable for a minimum water  
temperature of 200°F (93°C). Materials used must meet  
National Sanitation Foundation (NSF) specifications and  
all local plumbing codes and regulations.  
2. Provide the inlet line with a shut-off valve, (a full opening  
gate or ball type), one temperature/pressure gauge, and  
the pressure reducing valve. Set pressure reducing valve  
at 20 psi (138 kPa) flow pressure.  
CAUTION  
Do not connect booster water heater directly to a boiler or  
furnace coil or any other uncontrolled temperature  
source. The booster heater thermostat could be damaged  
causing unit to overheat.  
NOTE: A 3/4" union and  
for easy servicing.  
a
drain valve are required  
NOTE: Be sure water flows through the pressure reducing  
valve in the proper direction. Check directional arrow.  
Valve will reduce pressure only during flow conditions.  
Do not connect booster water heater to domestic  
(consumer) dish machines or other domestic utilized  
equipment. Hot water from booster heater may damage  
domestic equipment resulting in a hazardous condition.  
NOTE: An optional back pressure relief valve is available for  
installation on the water inlet line when local plumbing  
codes require a check valve.  
NOTICE  
3. Install a temperature/pressure gauge in both the inlet and  
outlet lines. Install the temperature sensing bulb in the  
water stream. The gauge must be mounted upright (see  
Figures 8 and 9).  
Use dielectric couplings when connecting dissimilar  
metals, such as galvanized to copper. This will prevent  
electrolysis or premature plumbing damage.  
NOTE: Tighten gauge during installation by only turning the  
1/2" brass nut. DO NOT turn the face of the gauge.  
Turning the face will cause inaccurate measurements.  
DO NOT turn or adjust inlet water connection on Magnum  
Series booster water heaters. Doing so will change the  
internal water flow.  
Do not back out or loosen any pipe fittings. Doing so may  
cause leaks.  
Do not lay unit on the side with the control panel. Damage  
to the unit could occur.  
Incoming water in excess of 3 grains of hardness per  
gallon (GPG) (0.75 grains of hardness per liter [GPL]) must  
be treated and softened before being supplied to booster  
heater(s). Water containing over 3 GPG (0.75 GPL) will  
decrease efficiency, increase energy use, and reduce the  
operating life of the unit through increased lime build-up.  
Product failure caused by liming or sediment buildup is  
not covered under warranty.  
Do not use deionized or reverse osmosis (R.O.) treated  
water in booster water heaters. Damage to booster heater  
may occur.  
NOTE: Product failure caused by liming or sediment buildup is  
not covered under warranty.

MAINTENANCE  
High Temperature Limit Safety Switch  
Blended Phosphate Treatment System  
(optional)  
Bradford White Commercial Electric Booster water heaters are  
equipped with a manually reset high temperature limit safety  
switch. If the temperature of the water in the heater exceeds  
210°F (99°C) the safety switch will shut off the power. The  
switch must be reset manually by pushing the red button.  
The Blended Phosphate Water Treatment System dispenses a  
small amount of polyphosphate into the water before the water  
enters the booster water heater. The mineral molecules in the  
water, which have a positive charge, are attracted to the  
negative charge of the polyphosphate. The mineral molecules  
are unable to join together, so scale is unable to form. Use the  
following procedure to replace a blended phosphate cartridge.  
Use the following procedure if the high temperature limit safety  
switch needs to be reset.  
1. Remove the access cover (see Figure 11).  
1. Shut off electrical power to the booster water heater.  
2. Push the red reset button on the high temperature limit  
safety switch.  
2. Shut off the inlet water supply and open drain shut-off valve  
to remove water in piping.

TROUBLESHOOTING GUIDE  
4. Booster water heater voltage must be correct for the  
voltage available. Check nameplate on the booster water  
heater for full information.  
General  
WARNING  
5. Water pressure at the inlet to the booster water heater must  
be adequate for proper operation of the rinse cycle of the  
dish machine, not to exceed 20 psi (138 kPa). Check with  
dish machine manufacturer for specific details.  
ELECTRIC SHOCK HAZARD:  
• Turn power OFF at disconnect switch/circuit breaker  
and allow unit to cool before performing any  
maintenance or cleaning.  
6. The breakers or fuses MUST be sized properly.  
• This unit must be serviced by qualified personnel only.  
Service by unqualified personnel may lead to electric  
shock or burn.  
7. Be sure that the temperature/pressure relief valve is one  
supplied by Bradford White and is installed properly.  
IMPORTANT! Many times when a booster water heater does  
not appear to be functioning properly, the fault is not with the  
booster water heater itself but with factors outside the heater.  
Before proceeding with the troubleshooting charts, perform the  
following steps first.  
8. A check valve should not be installed ahead of the booster.  
NOTE: If a check valve is installed and cannot be removed,  
install a back pressure relief valve set at 125 psi  
(862 kPa) on the incoming line between the pressure  
reducing valve and the inlet to the booster water  
heater. Discharge must be to open site drain.  
1. Check the temperature of the water feeding into the  
booster tank. It must be 110° to 140°F (43° to 60°C)  
depending on the heating capability of the unit. The inlet  
water supply must be in sufficient quantity to hold its  
temperature throughout the dishwashing operation.  
9. Primary water heater temperature should not exceed 160°F  
(71°C).  
2. If incoming water exceeds 20 psi (138 kPa), a pressure  
reducing valve must be installed.  
3. If the wash tank of the dish machine is filled through the  
booster water heater, this will use up all of the 180°F (82°C)  
water in storage. Sufficient time must be allowed to reheat  
the water in storage before starting the dishwasher.

ACCESSORIES  
Stainless Steel Adjustable Legs  
1. Carefully place the unit on its side.  
Floor Mounting Hardware  
Stainless steel adjustable legs with deck mounting flange are  
available for securing the booster heater to the floor.  
NOTICE  
Shock Absorber  
The shock absorber installed between the booster and the  
commercial dish machine reduces water hammer induced by  
rapidly operating valves. The water hammer can cause damage  
to the equipment.  
Do not lay unit on the side with the control panel. Damage  
to the unit could occur.  
2. Thread the adjustable legs into the existing leg holes on  
the bottom of the unit.  
Blended Phosphate Water Treatment  
System  
3. After all legs are secure, return the unit to the upright  
position.  
The Blended Phosphate Water Treatment System is installed  
before the booster water heater and reduces mineral scale  
build-up by introducing a measured amount of polyphosphate  
into the water.  
NOTE: If unit is not level, use an adjustable open-end wrench  
to adjust the foot of each leg until unit is level. Each leg  
is adjustable from 6″ (152 mm) to 7″ (178 mm).  
Bradford White recommends that the Blended Phosphate Water  
Treatment System be installed with unions on the incoming 3/4"  
water supply line after the pressure reducing valve and before  
the booster water heater.  
Cartridges supplied have a usage rating of 100,000 gallons  
(378,541 liters) of water. To assure proper operation the  
cartridges must be replaced when expired.  
NOTE: Product failure caused by liming or sediment buildup is  
not covered under warranty.
