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: INJURY HAZARD
All installation procedures must be performed by qualified personnel with full knowledge of all
applicable electrical and plumbing codes. Failure could result in property damage and
personal injury.
WARNING: ELECTRIC SHOCK HAZARD
Brewer must be properly grounded to prevent possible shock hazard. DO NOT assume a
plumbing line will provide such a ground. 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

INSTALLATION INSTRUCTIONS
READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION
CAUTION:
EQUIPMENT 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
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.
IMPORTANT:
This equipment must be
installed to comply with all
applicable federal, state and
local plumbing codes and
ordinances.
NOTE: Water supply inlet line
must mee t cer tain minim u m
criteria to insure successful
operation of the brewer.
Bloomfield recommends 1/4"
copper tubing for installation of
less than 25 feet and 3/8" for
more than 25 feet from a 1/2"
water supply line.
EQUIPMENT HAZARD
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 and Spray Disk are properly
installed.
LEVELING THE UNIT
Verify that an adjustable leg is installed at each corner of the
brewer, and that a rubber foot is installed on each leg.
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.
PLUMBER’S INSTALLATION INSTRUCTIONS (MODEL 8773
BREWERS ONLY)
Brewer should be connected to a POTABLE WATER, COLD
WATER line. Flush water line before connecting to Brewer.
DO NOT use a saddle valve with a self-piercing tap for the water
line connection. Such a tap can become restricted by waterline
debris. For systems that must use a saddle tap, shut off the main
water supply and drill a 3/16” (minimum) tap for the saddle
connection, in order to insure an ample water supply. Remember
to flush the line prior to installing the saddle.
The brewer must be installed on a water line with average
pressure between 20 PSI and 90 PSI. If your water pressure
exceeds 90 PSI at anytime, a pressure regulator must be
installed in the water supply line to limit the pressure to not more
than 90 PSI in order to avoid damage to lines and solenoid.
A water shut-off valve should be installed on the incoming water
line in a convenient location (Use a low restriction type valve,
such as a 1/4-turn ball valve, to avoid loss of water flow thru the
valve.
NSF requires that the brewer be able to be moved for cleaning
underneath. A flex line or loops of copper tubing will satisfy this
requirement. See Fig. 2 at right.

INSTALLATION INSTRUCTIONS (continued)
Fig. 2 Water Supply Installation - New-Style Brewers
In some areas, local codes require a backflow preventer (check
valve) to be installed on the inlet water line. If a backflow
preventer is used, you must install a water hammer arrester in
the incoming line, between the backflow preventer and the
brewer inlet, as far away from the brewer as space will allow.
This will relieve the excessive back pressures that can cause
faucet leaks and solenoid malfunctions.
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
automatic brewers are connected to the water supply.
Domestic models 8773 & 8774 are equipped with a cord and
plug. They require a 115 - 125 volt 15 amp circuit (50/60 Hz,
2 wire plus ground, with NEMA 5-15R receptacle).
Export models 8773 & 8774 are equipped with a cord and plug.
Refer to page 1 for circuit voltage requirements.
WARNING:
SHOCK HAZARD:
Brewer must be properly grounded to prevent possible shock hazard. DO NOT
assume a plumbing line will
provide such a ground.
Electrical shock will cause death
or serious injury.
IMPORTANT:
Do not connect brewer to
electrical power until the tank is
filled with water. Pour water
into the pour-over opening until
water flows from the brew head.
IMPORTANT:
Supply power must match
nameplate for voltage and
phase. 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
Fig. 3 Model 8773 Operation Diagram
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.
A. 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.
For automatic brewers, be sure the water supply is properly
connected and the water supply valve is turned ON.
BEFORE plugging the brewer into a receptacle, or otherwise
connecting brewer to electrical power THE WATER TANK MUST
BE FILLED. Place an empty container under the brew head. Lift
the pour-over cover then pour three decanters of warm tap water
into the pour-over opening. Water will begin to flow from the brew
head. When all wate r flow stops, empty the container.
Once the tank is full of water, connect the brewer to electrical
power. Press the tank heater switch to ON. 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.
Fig. 4 Fill the Tank

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.
To save energy, press the TANK HEAT
switch to OFF if no brew is expected for an
extended period.
WATER FLOW
POUR-OVER FEATURE (8773 & 8774)
Pouring any amount of cold water into the
pour-over opening and into the basin pan
forces an identical amount of hot water out
of the tank and through the spra y head into
the brew chamber.
AUTOMATIC OPERATION (8773 only)
Pressing BREW button energizes the
solenoid valve, allowing water from an
external water supply to flow into the basin
pan and then into the hot water tank. This
forces an identical amount of hot water out
of the tank and through the spra y head into
the brew chamber
The solenoid uses a flow control device so
that flow is consistent between 20 p.s.i. and
90 p.s.i.
Length of time the solenoid is open is
controlled by the timer.
HOT WATER FAUCET (8773 only)
The faucet water coil is submerged in the hot
water tank and draws heat from the brew
water. Water going to the water coil is not
controlled by the solenoid valve.
Hot water is provided at the faucet, at supply
water pressure, any time the faucet shut-off
valve is OPEN.
