PRECAUTIONS AND GENERAL INFORMATION
WARNING: Electric Shock Hazard
All servicing requiring access to non-insulated components must be performed by qualified
service personnel. Do not open any access panels which require the use of tools. Failure to
heed this warning can result in electrical shock.
WARNING Electric Shock Hazard
Brewer must be plugged into a properly grounded receptacle to prevent possible shock.
Electrical shock will cause death or serious Injury.
WARNING: Burn Hazard
This appliance dispenses very hot liquid. Serious bodily injury from scalding can occur from
contact with dispensed liquids.
This appliance is intended for commercial use only.
This appliance is intended for use to brew beverage products for
human consumption. No other use is recommended or
authorized by the manufacturer or its agents.
This appliance is intended for use in commercial establishments,
where all operators are familiar with the appliance use,
limitations and associated hazards. Operating instructions and
warnings must be read and unde r s to od by all operators and
users.
Except as noted, this piece of equipment is made in the USA
and has American sizes on hardware. All metric conversions
are approximate and can vary in size.
The following trouble shooting, component views and parts lists
are included for general reference, and are intended for use by
qualified service personnel.
This manual should be considered a permanent part of this

INSTALLATION INSTRUCTIONS
READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION
IMPORTANT:
To enable the installer to make
a quality installation and to
minimize installation time, the
following suggestions and tests
should be done before the
actual unit installation is started:
CAUTION: Equipment
Electrical Damage
DO NOT plug in or energize this
appliance until all Installation
Instructions are read and
followed. Damage to the
Brewer will occur if these
instructions are not followed.
CAUTION: Unstable
Equipment Hazard
It is very important for safety
and for proper operation that the
brewer is level and stable when
standing in its final operating
position. Provided adjustable,
non-skid legs must be installed
at each corner of the unit.
Failure to do so will result in
movement of the brewer which
can cause personal Injury and/
or damage to brewer.
WARNING ELECTRIC
SHOCK HAZARD:
Brewer must be plugged into a
properly grounded electrical
receptacle to prevent possible
shock hazard. DO NOT
assume a plumbing line will
provide such a ground.
Electrical shock will cause death
or serious injury.
Unpack the unit. Inspect all components for completeness and
condition. Ensure that all packing materials have been removed
from the unit.
Verify that the Spray Head Gasket (#33) and Spray Disk (#34)
are properly installed.
LEVELING THE UNIT
Verify that an adjustable leg is installed at each corner of the
brewer.
Set Brewer in its operating location. Level the Brewer. A spirit
level should be placed on the top of the unit, at the edge, as a
guide when making level adjustments.
Level the unit from left to right and front to back by turning the
adjustable feet. Be sure all four feet touch the counter to prevent
tipping.
FILL WATER TANK
Check the bottle ring for lint or packing materials. Wipe the
interior of the bottle ring with a cloth dampened with clean water.
Brewer is designed to use a 3 gallon or 5 gallon plastic water
bottle. Carefully insert a fresh water bottle into the bottle ring.
Wait 30 seconds, or until all bubbling in the bottle stops, then
drain water from the hot water faucet until all ai r is purged from
the tank.
ELECTRICIAN’S INSTALLATION INSTRUCTIONS
REFER TO ELECTRICAL SPECIFICATIONS - Page 1
Check the nameplate to determine correct electrical service
required for the Brewer to be installed.
IMPORTANT: Before connecting to electricity, make sure a
bottle of water is installed on the bottle ring, and all air has been
bled from the water tank
Model 8372 is equipped with a cord and plug. It requires a 115 125 volt 20 amp circuit (50/60 Hz, 2 wire plus ground, with NEMA
5-15R or 5-20R Receptacle).
IMPORTANT:
Supply power must match nameplate for voltage and phas e.
Connecting to the wrong voltage will damage the brewer or result
in decreased performance. Such damage is not covered by
warranty.
IMPORTANT: The ground prong of the plug is part of a system
designed to protect you from electrical shock in the event of
internal damage. Never cut off the ground prong nor twist a
blade to fit an existing receptacle. Contact a licensed electrician
to install the proper circuit and receptacle.

OPERATION
START-UP
For initial start-up, or if the brewer has not been used for an
extended period of time:
♦ Be sure spray disk and brew gasket are properly installed
in the brew head.
♦ Install a fresh bottle of water in the bottle ring.
♦ Allow basin and tank to fill.
♦ Plug unit into a properly grounded electrical receptacle.
♦ Draw water from the hot water faucet until all air is purged
from the tank.
NOTE: This brewer will not function as a “pour-over” brewer. A
water bottle with an adequate amount of water must be installed
for the brewer to operate.
Once plugged into electrical power, the heating elements will
begin heating the water in the tank. When the water has reached
the proper temperature, the “READY TO BREW” light will glow.
CAUTION:
Personal Injury
5 Gallon water bottle can weigh
up to 50 pounds. Install bottle
carefully. Injury can result from
improper lifting technique or
from attempting to lift a full bottle
without adequate physical
ability.
CAUTION: Equipment
Electrical Damage
DO NOT manually fill brewer
through bottle ring.
IMPORTANT: Use only 3 gallon
or 5 gallon plastic water bottle.
IMPORTANT:
Tank must be full of water
before connecting brewer to
electrical power.
Heating elements will be
damaged if allowed to operate
without being fully submerged in
water. Damage caused by
operating the brewer without
water in the tank is NOT
COVERED BY WARRANTY.
IMPORTANT:
This appliance is NOT designed
to be used as a pour-over
brewer. Operation without a
water bottle with an adequate
amount of water in place will
produce very little or no brewed
coffee.
IMPORTANT:
When installing water bottle, be
careful to not overflow the basin
pan. DO NOT fill the basin pan
prior to installing the water
bottle.
Fig 2. Brewer Operation Diagram
5
OPERATION (continued)
WATER HEATER
Water temperature is sensed by a
thermobulb inserted into the water tank. This
temperature signal is fed to the thermostat,
which controls line power to the heating
element.
The setpoint temperature is adjustable at the
thermostat.
The element is protected from overtemperature by a hi-limit thermostat.
WATER FLOW
AUTOMATIC OPERATION
Water is supplied to the hot water tank by a
bottle inserted in the bottle ring. Water will
flow from the bottle into the basin pan until
the water level reached the open mouth of
the bottle.
Pressing BREW button energizes the
solenoid valve, allowing heated water from
the hot water tank to flow through the spray
head into the brew chamber.
The length of time the solenoid is open is
controlled by the timer.
HOT WATER FAUCET
The hot water faucet draws heated water
from the water tank.

BREWING COFFEE
PREPARATION
Place one (1) genuine Bloomfield paper filter in the brew chamber.
Add a pre-measured amount of fresh coffee grounds.
Gently shake the brew chamber to level the bed of grounds. Slide
the brew chamber into place under the brew head.
AUTOMATIC OPERATION
BE sure “READY TO BREW” light is lit.
Place an EMPTY decanter in place under the brew chamber.
Press the “BREW” switch. The solenoid will open for an amount of
time determined by the timer setting, admitting a measured quantity
of hot water into brew head, where it will spray over the bed of
grounds.
When the flow and all dripping stops, the coffee is ready to serve.
Discard the contents of the brew chamber and rinse it in a sink.
When the ”READY TO BREW” light comes on, the brewer is ready
for another brew cycle.
Fig. 5 Brew Chamber
CAUTION:
Burn Hazard
Exposed surfaces of the
brewer, brew chamber and
decanter may be HOT to
the touch, and can cause
serious burns.
CAUTION:
Burn Hazard
To avoid splashing or overflowing hot liquids,
ALWAYS place an empty
decanter under the brew
chamber before starting
the brew cycle. Failure to
comply can cause serious
burns.
CAUTION:
Burn Hazard
After a brew cycle, brew
chamber contents are
HOT. Remove the brew
chamber and dispose of
used grounds with care.
Failure to comply can
cause serious burns.
NOTE: Use of the hot
water faucet will not affect
the volume of water
delivered for a brew.
However, overuse of the
faucet during a brew may
lower the temperature of
the brew water.
