IMPORTANT SAFETY INFORMATION
Form No. EBOOSTERBWM-1009
2
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.
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.
Follow standard welding safety and operational
procedures when attaching sliderails to bottom of dish
table.
This product contains fiberglass, a product known to the
state of California to cause cancer, birth defects or other
reproductive harm.
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.
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.
BURN HAZARD:
• Water in unit is very hot. Wear protective gloves and
proper attire when operating to avoid injury.
• Some exterior surfaces on unit will get hot. Avoid
unnecessary contact with unit.
• 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 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.
WARNING
CAUTION
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.
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.
NOTE: The pressure reducing valve must be the type
equipped with a high pressure bypass, like the valve
supplied with this booster water heater.
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.
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.
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.
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.
