INSTALLATION INSTRUCTIONS
READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION
IMPORTANT:
REFER TO EXPLODED VIEWS PAGES 18 thru 22 FOR
COMPONENT NAMES/NUMBERS
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:
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.
CAUTION: Equipment
Electrical Damage
LEVELING THE UNIT
Verify that an adjustable leg is installed at each corner of the
brewer.
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.
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.
CAUTION: Unstable
Equipment Hazard
PLUMBER’S INSTALLATION INSTRUCTIONS
Brewer should be connected to a POTABLE WATER, COLD
WATER line. Flush water line before connecting to Brewer.
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.
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.
NOTE: Water supply inlet line
must meet certain minimum
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.
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.
The provided water line strainer must be installed in the supply
line, between the shutoff valve and inlet fitting. Note FLOW
arrow marking on strainer body.
4
INSTALLATION INSTRUCTIONS (continued)
NOTE: This equipment must be
installed to comply with
applicable federal, state and
local plumbing codes and
ordinances.
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 Figure 2 below.
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.
Fig. 2 Water Supply Installation
New-style shown
Electrical shock will cause death
or serious injury.
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.
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:
ELECTRICIAN’S INSTALLATION INSTRUCTIONS
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.
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.
All models (except 8574) are equipped with a cord and plug.
They require a 115 - 125 volt 20 amp circuit (50/60 Hz, 2 wire
plus ground, with NEMA 5-15R or 5-20R Receptacle).
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.
Model 8574 must be wired by an electrician, and requires a
115/230V 20A circuit (50/60 Hz, 2 hot legs / 1 neutral leg, plus
ground). Remove rear panel to gain access to terminal block.
Green terminal must be connected to a suitable building ground.
Circuit must be capable of 3800 Watts. See figure 3 at right.
Fig. 3 115/240 Volt Terminal Block
IMPORTANT: Wiring must be installed in approved solid or
flexible conduit, and must be secured to the brewer with a strain
relief (to be provided by the installer).

OPERATION
Fig. 4 Brewer Operation Diagram
IMPORTANT:
A. START-UP
Tank must be full of water
before connecting brewer
to electrical power.
For initial start-up, or if the brewer has not been used for an
extended period of time:
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.
♦ Be sure spray disk and brew gasket are properly installed in the
brew head.
♦ Be sure the water supply is properly connected and the water
supply valve is turned ON.
♦ Be sure the WATER TANK IS FILLED
BEFORE plugging the brewer into a receptacle, or otherwise
connecting brewer to electrical power THE WATER TANK MUST
BE FILLED. Place an empty decanter under the brew head. Lift
the pour-over cover then pour warm tap water into the pour-over
opening until water flows from the brew head. When water stops
dripping from the brew head, empty the container.
Once the tank is full of water, connect the brewer to electrical
power. The heating elements will begin heating the water in the
tank. When the water has reached the proper temperature, the
“HEAT” light will go out.

OPERATION (continued)
WATER HEATER
HI-LIMIT
THERMOSTAT
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.
THERMOBULB
The setpoint temperature is adjustable at the
thermostat.

WATER FLOW
POUR-OVER FEATURE
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 spray head into
the brew chamber.
AUTOMATIC OPERATION
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 spray 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
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.
The faucet is at supply water pressure any
time the faucet shut-off valve is OPEN.
