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
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.
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.
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.

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:
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.
NOTE: This equipment must
be installed to comply with
applicable federal, state and
local plumbing codes and
ordinances.
WARNING:
SHOCK HAZARD
IL1615
Fig. 2 Water Supply Installation
645 p/n DD-75908 Owners Manual Dual Airpot And Thermal Coffee 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.
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.
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).

OPERATION
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.
•
•
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.
Be sure the water supply is properly connected and the water
supply valve is turned ON.
Be sure the WATER TANK IS FILLED

645 p/n DD-75908 Owners Manual Dual Airpot And Thermal Coffee Brewers
Fig. 4 Brewer Operation Diagram
OPERATION (continued)
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.
Fig. 5 Heat Control Diagram
WATER FLOW
POUR-OVER FEATURE
Pouring any amount of water into the pourover opening and into the basin pan forces
an identical amount of heated water out of the
tank and through the spray head.
645 p/n DD-75908 Owners Manual Dual Airpot And Thermal Coffee Brewers
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.
Fig. 6 Water Flow Diagram
Hot water is provided at the faucet, at supply
water pressure, any time the faucet shut-off
valve is OPEN.

OPERATION (continued)
IMPORTANT:
DO NOT energize this
brewer until the water
tank has been filled. Dry
firing will damage heating
elements. See page 6.

At the conclusion of the brew cycle, three beeps will sound.
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.

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 immediately return
the brewer to normal
operation.
645 p/n DD-75908 Owners Manual Dual Airpot And Thermal Coffee Brewers
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.
IMPORTANT:
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 will

SYMPTOM
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).
CAUTION:
SHOCK HAZARD
Live electrical circuits may be
exposed while performing
these procedures.
These procedures are to
be performed by qualified
technical personnel only.
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 will trip the high limit.
Tank must be properly filled as
detailed on page 6.
Check hi-limit (see below)
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.
Brewer will go into error mode
immediately if either the control board
or temp probe is defective.
Temp probe electrical resistance is
approximately 30KW at room temp,
and 2KW at boiling. Replace temp
probe if less than 1KW.
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.
Check power board
and heating element.
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.
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.
Is the brew
temperature
properly adjusted?
The brewer may occasionally go into
error mode if the brew temperature is
set too high.
See page 15 for temperature
adjustment procedure.

Fig. 13 Checking and Adjusting Brew Temperature
645 p/n DD-75908 Owners Manual Dual Airpot And Thermal Coffee Brewers
Pull vent tube out of tank lid and insert a thermometer of known
accuracy in vent hole. Reconnect brewer to electrical power.
Place empty container under brew chamber. Energize brewer
and pour one decanter (64 oz.) of cold water into pour-over
opening. When HEAT light goes out, read the temperature
displayed on thermometer.
Adjust WATER TEMP dial on controller; clockwise increases
temperature. Refer to Table 1 below for proper brewing
temperature based on altitude.
NOTE: Optimum brewing
temperature is 195ºF to 205ºF
(90ºC to 96ºC).
Maximum temperature setting
should be no more than 205ºF
(96ºC).
Table 1
IMPORTANT:
An electronic temperature controller will maintain
temperature within ±2ºF.
To prevent boiling water in
the brewer, controller should
be adjusted to a maximum
temperature equal to the local
boiling temperature minus 2ºF,
or 205ºF, whichever is less.
Boiling Temperature by Altitude
Upon completion, remove thermometer and reinstall vent tube.
15
SERVICING INSTRUCTIONS (continued)
IMPORTANT: Water pressure
must be between 20 p.s.i and
90 p.s.i. flowing pressure. If
water pressure exceeds this
value, or if water pressure
varies greatly, a pressure
regulator must be installed in
the water supply line.
BREW TIME ADJUSTMENT
The amount of water dispensed automatically during a brew cycle
is controlled by the SOLENOID TIME dial of the controller.
Place empty decanter under brew chamber. Press BREW
button. Brewer should dispense one full decanter of water. To
adjust amount:
Remove brew chamber and button plug. On the controller, adjust
SOLENOID TIME dial (BREW TIME); clockwise increases time.
