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 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.
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.
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
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.
Plumber must provide two 1/4” female flare water supplies for this
brewer.
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.
645 75908 Owners Manual E.B.C. Dual Airpot/Thermal Brewer

INSTALLATION INSTRUCTIONS (continued)
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.
Fig. 2 Water Supply Installation
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.
Brewers must be wired by an electrician, and require a dedicated
115/230V or 120/240V 20A circuit (50/60 Hz, L1, L2, Neutral,
plus ground). Remove front panel to gain access to terminal
block. Green terminal must be connected to a suitable building
ground. Circuit must be capable of 4000 Watts (model 1090 and
1092) or 7000 Watts (model 1091 and 1093).
See figure 3 at right.
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).
NOTE: This equipment must be
installed to comply with
applicable federal, state and
local plumbing codes and
ordinances.
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.

OPERATION
Fig. 4 Brewer 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.
♦ 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 TANKS MUST
BE FILLED. Place an empty decanter under each brew head. Lift
the pour-over cover then pour tap water into each pour-over
opening until water flows from the brew heads. This will require the
equivalent of three full 64oz. Decanters per side. When water stops
dripping from the brew head, empty the container.
Once the tanks are full of water, connect the brewer to electrical
power. For Models 1091 & 1093, press power 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” LED will glow.
645 75908 Owners Manual E.B.C. Dual Airpot/Thermal Brewer

WATER HEATER
Water temperature is sensed by an electronic water
temperature probe inserted into the water tank.
This temperature signal is fed to the controller.
The setpoint temperature is adjustable. The
controller sends a command signal to the power
board based upon a comparison between the
setpoint temperature and actual temperature.
See page 15.
The power board energizes the heating elements
based on the command signal from the controller.
Excessive temperature will trip the hi-limit safety
switch. The hi-limit will automatically reset when
the brewer cools.
WATER FLOW
POUR-OVER FEATURE
Pouring any amount of water into the pour-over
opening and into the basin pan forces an identical
amount of heated water out of the tank and through
the spray head.
AUTOMATIC OPERATION
Pressing the BREW key energizes the solenoid
valve, allowing water from an external water supply
to flow into the water tank. The incoming water
forces heated water out of the tank to perform the
brew.
The solenoid uses a flow control device so that
flow is consistent between 20 p.s.i. and 90 p.s.i.
The length of time the solenoid is open is controlled
by the time setting of the controller. See page 18.
After the solenoid closes, water will continue to flow
to the brew chamber until
the water level in the tank falls below the brew
pickup, breaking the siphon.
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.
Hot water is provided at the faucet, at supply water
pressure, any time the faucet shut-off valve is
.

is more than 10ºF below the setpoint, the HEAT indicator will glow until
water temperature reaches setpoint.
Press the ON/OFF key again to turn the brewer
OFF. Three beeps will
sound, the tank heater and all warmers will be switched off, and all
indicator lights will go out.
Brew Settings
See pages 15 & 16 for setting Brew Time and Temperature.
ABS™ (Automatic Brew Start)
Start a brew by pressing BREW. A single beep will sound. The system
will verify that the water in the tank is at the proper temperature. If it is,
brew will start immediately. Otherwise, the BREW indicator will flash
(Brew Waiting Mode) until the water reaches setpoint temperature,
then the indicator will glow and brew will commence. If the main
warmer is off, it will be energized automatically.
At the conclusion of the brew cycle, three beeps will sound.
NOTE: To override Brew Waiting Mode, press and hold the BREW
key for 3 seconds while the BREW indicator is flashing. Brew will
begin regardless of water temperature. To avoid under-temperature
brews, this feature should only be used when setting brew volumes.
NOTE: Brew Waiting Mode (BREW indicator flashing) prevents
multiple, unattended brews. While the BREW indicator is on or
flashing, any additional strokes of the BREW key will be ignored (there
will be a beep each time the key is pressed, however). Another brew
cannot be initiated until the previous brew is complete.
The Brew Waiting Time, also called Dripout Time, (interval between
when the brew is initiated and the audible signal sounds at the end
of the brew) may be adjusted between 2 and 8 minutes at the Brew
Signal Timer dial on the controller. See page 16.
Brew Cancel
To cancel a brew in progress or a brew in waiting, press the CANCEL
key. Two beeps will sound and the BREW indicator will go out.
NOTE: If a brew in progress is cancelled, coffee will continue to flow
until all water delivered has dripped through the brew chamber.

OPERATION (continued)
Quality Timer
Coffee looses freshness as it sits on a warmer. The Quality Timer
flashes the warmer lights 30 minutes after the last brew to remind you
that the coffee is nearing the end of its useful life.
After Hours™ Operation
During normal operation, the controller will maintain the precise
brewing temperature. If, however, if the BREW key in not pressed for
3 hours, the brewer goes into After Hours™ mode; any warmer left on
will be turned off; and, the temperature will only be maintained to within
20ºF. This feature prolongs component life and saves energy.
As soon as the BREW key is pressed, the brewer returns to normal
operation, heating the water to the precise temperature before
beginning the brew. The brewer will return to After Hours™ mode only
if three hours pass without a brew being initiated.
Disable/Enable After Hours™ Feature
To disable After Hours™, press the ON/OFF key to turn the brewer
Press and hold the CANCEL key until two beeps sound, and the HEAT
indicator flashes twice. This feature is now disabled.
To re-enable After Hours™, press the ON/OFF key to turn the brewer
OFF. Press and hold the CANCEL key until three beeps sound, and the
POWER indicator flashes twice. This feature is now enabled, however,
it will not be activated unless no brew is initiated for three hours.
Over-Temperature and Temperature Fault Protection
Should the water temperature exceed 214ºF (101ºC), or if the controller
does not detect a 2ºF (1ºC) rise in temperature within four minutes of
calling for heat, the brewer will go into Over Temperature Mode; the
heating element is turned off, all warmers are disabled and all lights will
flash.
Possible causes of Over Temperature condition:
• Setpoint is in the boiling range.
• Heating element or temperature probe has malfunctioned.
• Excessive scale buildup is preventing the element from heating the
water.
• Heating element relay fails in the “on” state.
• No water in the tank.
• Hi-limit safety tripped (must be manually reset)
To reset the brewer:
• Determine the cause of the failure and take appropriate remedial
action to rectify the problem.
• Press and hold the CANCEL key for three seconds. Four beeps
645 75908 Owners Manual E.B.C. Dual Airpot/Thermal Brewer
will sound and the brewer will resume normal operation.
OFF.
Quality Timer is normally
set for 30 minutes. It can
be set for 20 minutes by
moving a jumper on the
controller. See page 19.
After Hours™ is an energy
saving feature. The
brewer will enter After
Hours™ mode if it is not
used for three hours.
Press the BREW key to

ERROR DETECTION
This brewer is designed to perform a continuous internal
diagnosis, and to signal faults by flashing all the lights. In fault
mode, warmers, heating element and water fill solenoid are turned
“off”, and most keypad functions are disabled.
Error detection (all lights flashing) will occur under two conditions:
• Anytime a temperature in excess of 214ºF is detected.
• Temperature does not change by at least 2ºF within 4 minutes
of tank heater being energized (HEAT light on).
Live electrical circuits may
be exposed while performing
these procedures.
These procedures are to be
performed by qualified
technical personnel only.
CAUTION:
SHOCK HAZARD
To reset the brewer after the fault has been corrected, press and
hold the CANCEL key for 3 seconds, or disconnect the brewer from
electrical power for three seconds.
WHAT TO CHECK DESCRIPTION CORRECTIVE ACTION
Has the water tank
been properly filled?
On initial startup, an attempt to heat a
dry tank will be detected as too high a
temperature or insufficient temp rise, or
Tank must be properly filled as
detailed on page 6.
Check hi-limit (see below)
will trip the high limit.
Has hi-limit safety
thermostat tripped
off?
Brewer may have been started without
water in the tank, or the temp control
thermostat may require adjustment.
Access hi-limit by removing front
panel. Hi-limit is on the left side of
the tank. Use an insulated tool to
push the red button in until it “clicks”
and stays. Reset per above.
Check control board
and temp probe.
Check power board
and heating element.
Is the brew
temperature properly
645 75908 Owners Manual E.B.C. Dual Airpot/Thermal Brewer
adjusted?
Brewer will go into error mode
immediately if either the control board
or temp probe is defective.
Temp probe electrical resistance is
approximately 30KΩ at room temp, and
2KΩ at boiling. Replace temp probe if
less than 1KΩ.
Brewer will go into error mode 4 minutes
after energizing the heating element if
insufficient heat rise is detected. The
heating element is energized by an
electronic power board, and protected
by the hi-limit safety.
Heating element should receive full line
voltage (i.e. 120V, 208V or 240V).
Be sure the hi-limit safety is reset.
The brewer may occasionally go into
error mode if the brew temperature is
set too high.
Reset by holding the CANCEL key for
3 seconds. If lights continue to flash:
Disconnect temp probe from control
board.
a. If lights continue to flash, unplug
brewer and replace control board.
b. If lights stop flashing, unplug
brewer and replace temp probe.
Reset by holding the CANCEL key
for 3 seconds. If lights resume
flashing after 4 minutes:
Check the voltage across the heating
element terminals:
a. If no voltage is present, unplug
brewer and replace power board.
b. If proper voltage is present,
unplug brewer and replace tank
heating element.
See page 15 for temperature
adjustment procedure.
