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 12 feet and 3/8” for
more than 12 feet from a 1/2”
water supply line.
REFER TO EXPLODED VIEWS Pages 18 thru 20 for
COMPONENT NAMES/NUMBERS
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.
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.

IL2681
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
643 2M-Z17088 Owners Manual 1883 E.B.C. Lo-Profile Airpot Brewer,
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.

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.
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.

The hot water will be forced into the brew head where it will spray over the bed of grounds. Freshly brewed coffee will begin to fill the container under the brew chamber.
At the end of the brew cycle, plus an amount of time set to allow all water to drip out of the brew chamber, two beeps will sound. 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 glows, the brewer is ready for another brew cycle.
NOTE: The brewer will not
initiate a second automatic
brew cycle until the current
cycle plus the drip-out time
is completed. If the BREW
key is pressed during this
time, the BREW light will
flash, indicating a brew in
progress.
NOTE: Water for the hot
water faucet is heated in
a coil inside of the water
