INSTALLATION INSTRUCTIONS
READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION
IMPORTANT:
Unpack the unit. Inspect all components for completeness and
condition. Ensure that all packing materials have been removed
from the unit.
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:
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.
CAUTION: Equipment
Electrical Damage
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.
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.
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
CAUTION: Unstable
Equipment Hazard
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.
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.
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.
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 waterline filter is recommended in areas where water quality
may cause taste and/or odor problems.
4
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: 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
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.
ELECTRICIAN’S INSTALLATION INSTRUCTIONS
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.
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 1080 and 1082 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.
Models 1086 & 1088 must be wired by an electrician, and
require a 115/230V 20A circuit (50/60 Hz, 2 hot legs / 1 neutral
leg, 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 3500 Watts.
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
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. For Models 1086 & 1088, 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
“HEAT” LED will go out.
6
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 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
OPEN.

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

OPERATION (continued)
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.
Quality Timer
Coffee looses its 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
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

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:
If the original cause of the
problem has not been
addressed, the brewer will
once again go into Over
Temperature mode four
minutes after being reset.
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.

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.
Run several cycles to check amount of water delivered.
DRIPOUT TIME ADJUSTMENT
Water delivered to the brew chamber will take a while to drip
through as coffee. The time between the end of a brew and
when a new brew can be initiated is controlled by the BREW
SIGNAL TIMER. Adjust the BREW SIGNAL TIMER dial on the
controller to account for the dripout time. Replace button plug.
