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
EQUIPMENT HAZARD
It is very important for safety
and for proper operation that the
brewer is level and stable when
standing in its nal 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.
Bloomeld 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 ush 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 ow thru the
valve.
The provided water line strainer must be installed in the supply
line, between the shutoff valve and inlet tting. Note FLOW
arrow marking on strainer body.

In some areas, local codes require a backow preventer (check
valve) to be installed on the inlet water line. If a backow
preventer is used, you must install a water hammer arrester in the
incoming line, between the backow 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.
Models 1883 and 1883CA 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: Fill the water tank before energizing this unit:
1. Insert the brew chamber (empty) and place an empty airpot

2. Plug the unit into an appropriate receptacle.
3. Be sure the brewer is “off” (I.e. no LEDs are lit).
4. Press BREW key three (3) times.
5. Press CANCEL key once.
IL2680
6. When water starts to ow from the brew chamber, press
POWER key once. Unit will begin heating water in
preparation for the rst brew.
NOTE: This equipment must
be installed to comply with
applicable federal, state and
local plumbing codes and
ordinances.
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.
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: Do not connect
brewer to electrical power until
you are ready to ll the tank.
See instructions at left.
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 t an
existing receptacle. Contact a
licensed electrician to install the
proper circuit and receptacle.

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.
WATER FLOW
AUTOMATIC OPERATION
Pressing the BREW key energizes the
solenoid valve, allowing water from an
external water supply to ow into the water
tank. The incoming water forces heated
water out of the tank to perform the brew.
The solenoid uses a ow control device so
that ow 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. After the solenoid closes, water
will continue to ow to the brew chamber
until the water level in the tank falls below the
brew pickup, breaking the siphon.
OPERATION (continued)
