INSTALLATION INSTRUCTIONS
READ THIS CAREFULLY BEFORE STARTING THE INSTALLATION
IMPORTANT:
UNPACKING & INITIAL INSPECTION
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:
1. Unpack the unit. Inspect all components for completeness
and condition. Ensure that all packing materials have been
removed from the unit.
2. (See page 13) Verify that the Spray Head and Spray Head
Gasket are properly installed.
LEVELING THE UNIT
CAUTION: Equipment
Electrical Damage
1. Verify that an adjustable leg is installed at each corner of the
brewer.
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.
2. Set Brewer in its operating location.
3. 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.
4. 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.
CAUTION: Unstable
Equipment Hazard
PLUMBER’S INSTALLATION INSTRUCTIONS
1. Brewer should be connected to a POTABLE WATER, COLD
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.
WATER line. Flush water line before connecting to brewer.
2. 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.
3. 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 filters, lines
and solenoid.
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.
4. 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.

INSTALLATION INSTRUCTIONS (continued)
For ‘Filter-Ready” units, refer to filter installation and hook-up
instructions packed with the brewer.
NOTE: This equipment must
be installed to comply with
applicable federal, state and
local plumbing codes and
ordinances.
5. 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.

6. In some areas, local codes require a backflow preventer
(check valve) to be installed on the inlet water line. If a back
flow 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.
Electrical shock will cause death
or serious injury.
IMPORTANT: Do not attempt to
override the automatic tank fill
feature which requires that the
tank must be full of water to
start operations. Any attempt to
override this feature will void
the warranty.

KEY: two beeps will sound and the “Brew” light
will go out. Water flowing to the brew chamber
will be stopped immediately, but if there is
already water in the brew chamber, it will take a
few moments before this drips through as
coffee.
The brew key is disabled
during a brew cycle. This
minimizes the possibility
of double brewing.
When the “Brew” light is
on or flashing, repeated
pressing of the BREW
switch will be ignored,
(there will be a beep each
time it is pressed). A
Brew will only be activated
when the “Brew” light is
off.
4. Normal Operation (Non Brewing): When the unit is not brewing,
the E-Max™ maintains the water temperature at the Precise
Temperature for Brewing™ (PTB™). The heating element will
cycle on and off automatically to maintain this temperature.
5. After Hours Mode: If no brew is detected for a pre-selected length
of time, the brewer will enter the After Hours mode. Temperature
will be allowed to drop to save energy. Pressing the BREW KEY

Temporarily Overriding the Automatic ON/OFF function. While in the automatic timed OFF
mode the brewer can be started by depressing the ON/OFF switch. The brewer will remain
ON until the automatic programmed off time, when it will turn OFF and resume normal
automatic timed functioning. Similarly, if turned OFF during the automatic timed ON mode
the brewer will remain OFF until the next programmed on time, when it will turn on and
resume normal automatic timed functioning.
5. Automatic Start-Up in Previous Mode: If the E-Max™ automatic timer is OFF (the factory
setting) and power is disconnected, the brewer will start up when power is restored, in the mode
it had been in prior to the power disconnection. If the E-Max™ has the timer setting ON and
power is disconnected, the brewer will start up in the mode that it should be in at the time the
power is restored.
6. Viewing Programmed Brew Volume: The E-Max™ can have up to 4 different brew volumes.
When a volume other than the standard, or first brew volume, is selected, the E-Max™ will
complete that volume and then automatically reset to the standard, or first brew volume. With the
brewer ON, press and hold the CANCEL key. The 1st, or standard, volume will be displayed for

also be done in the regular programming mode. Consult the E-Max™ Programming Manual)
C. After Hours™: Consult the E-Max™ Programming Manual to set the After Hours™ mode.
The factory programming has the After Hours™ mode turned OFF. The After Hours™ can be
programmed to come on from 1 to 6 hours after the last brew. When the E-Max™ goes into
the After Hours™ mode, any warmer plates left on will be turned off (on decanter brewers),
the water in the tank will be allowed to drop from the normal brewing temperature and will re
heat less frequently – this feature saves energy and extend component life. While in the After
Hours mode, the power light will flash continuously. When the BREW switch is pressed the
E-Max™ automatically reverts back to normal operation, heating the water to the Precise
Temperature for Brewing™ (PTB™), before starting the brew. (The power light will be on
continuously and the Brew light will flash until the correct water temperature is reached.)
9. Countdown Quality Timer™: The E-Max™ factory programming has the Countdown Quality
Timer™ turned OFF. Consult the E-Max™ Programming Manual to activate the Countdown
Quality Timer™ feature:
This feature offers independent Countdown Quality Timers for each warmer plate. The count
down timer can be set from 20 to 360 minutes (in 5-minute increments). When a warmer plate is
turned on (or, for the main warmer, as soon as a brew is complete,) the countdown time begins.
At the end of the selected time there will be two beeps and the warmer plate light will flash
continuously until reset. While the light is flashing the heating element for the warmer plate
remains on. Push the warmer plate switch to turn the warmer off, and switching it again will
re-start the countdown time.
10. Pulse or Pre-Infusion Volume Options: To set these features, refer to E-Max™ Programming
Manual, Brew Settings Menu. If a particular brew volume has utilized the pulse or pre-infusion
option, that volume will be displayed with an asterisk (*) after the volume. As an example
“Volume#2 64oz*” would indicate that the second programmed brew volume has utilized the
pulse or pre-infusion program options.
11. Keypadlock™: This feature is OFF in the standard factory settings. To set the feature refer to
E-Max™ Programming Manual, Machine Settings Menu. If the Keypadlock™ feature is activated,
there will be no response by the brewer when the keys are depressed (except for the beep after a
key is depressed). To temporarily “unlock” the keypad, press and hold the CANCEL key for 6
seconds. A beep will be heard indicating the keypad is now “unlocked”, — a brew can be initiated,
warmer plates turned on or off, etc. The keypad will remain unlocked until the brew is completed,
then automatically return to keypadlock™ mode. If a brew is not initiated 60 seconds after
“unlocking”, the system will time out and return to the “locked” position.

13. Diagnostic Messages – Programmed Safety Features: When the E-Max senses a problem,
it will automatically turn off all elements and valves, flash lights, display the message
“Call For Service” and display one of the messages below. (Additionally: a service phone
number may appear if it has been programmed into the system.)
*To reset the brewer it can be re-energized (or press and hold CANCEL for 3 seconds for all
faults except the Valve Fault, which must be reset by re-energizing). The brewer will try to
re-start, but if the same problem persists, the appropriate error message will appear again.
Consult the Trouble Shooting section to determine how to solve the problem.
A. “Probe/Heater Error”: Overheating Detection (1): If the heating element is on for 5 minutes
and the temperature does not change by +2°F (1°C) in the five minute period, the unit will go
into the Over Temperature Mode with all lights flashing. When in this mode the brewer turns
off the heating elements, the solenoid valves are turned off; the switches disabled; (and all
lights flashing continuously). The LCD display will read “Probe/Heater Error”, followed by the
message “Call for Service”, and then the service phone number (if it has been entered into
memory). To reset press and hold CANCEL for 3 seconds, or re-energize the brewer.
(Possible causes of problem: high limit needs to be re-set; defective high limit, element, triac,
water level probe or control board.)
B. “Overheat Error”: Overheating Detection (2): If the E-Max™ senses a temperature over the
Maximum Temperature set in the program (factory set at 208ºF or 98ºC) it will go into the over
temperature mode as above with all lights flashing, except the LCD will read “overheat error”,
and “Call for Service”. To reset press and hold CANCEL for 3 seconds, or re-energize the
brewer. (Possible cause of problem is a defective triac, temperature probe or related wiring
and connections.)
C. “No Water Sensed” — Time-Out —Inlet Valve: When filling for the first time, the inlet valve
will remain open for 4¼ minutes, (the screen will read “filling…”). If water is not detected at
the end of this time the E-Max will shut down with the message “no water sensed”. The
valves and all elements are turned off, and the Brew and Power light flash alternately with the
Heat light, until the brewer is reset. To reset press and hold CANCEL for 3 seconds, or
re-energize the brewer. (Possible causes of the problem are: no incoming water; slow flow of
incoming water (i.e. less than 45 oz/minute); sensor not reading (check for placement,
connections or lime scale).
D. “No Water Sensed” — Time-Out – Brew Valve: During the brew the inlet solenoid valve
cycles on intermittently to maintain the proper level in the tank. If the valve is open for
60 seconds without water being detected at the proper level, the brewer will go into the same
error mode as above (“no water sensed”). To reset press and hold CANCEL for 3 seconds,
or re-energize the brewer. (Possible causes of the problem are: no incoming water; slow flow
of incoming water, sensor not reading, etc.).
E. Keyswitch Locked: If a key switch is depressed for 10 seconds this error message will
occur. Lights will flash alternately and the brewer will turn off all valves and elements. Press
and hold the CANCEL key for 3 seconds to reset the brewer (or re-energize the brewer). If
the problem re-occurs this indicates a defective switch on the key pad.
F. “Valve Fault”- Faulty Valve Detection: When an electric or switching problem is detected
with either the inlet or brew valve the brewer turns off all elements and valves and displays
“valve fault…”. All of the lights will be turned on. Before re-setting the brewer the valves
must be checked to determine the problem. The brewer must be re-energized to re-set,
(pressing CANCEL for 3 seconds will not reset a valve fault).

FUNCTION
WARNING:
RISK OF INJURY
1. Pressing the POWER key energizes the unit. The
POWER LED will glow whenever the unit is ON.
The following servicing sections
are for operator reference only.
All servicing and/or repairs must
be performed by a qualified
technician
2. Automatic fill is accomplished via a FILL SOLENOID
(32) and a WATER LEVEL PROBE (7). The probe
senses ground through the water in the tank. When the
water level falls below the probe and ground is no longer
sensed, the CONTROLLER (20) energizes the fill
solenoid (32) until the water level again reaches the
water level probe.

SERVICING INSTRUCTIONS — DE-LIMING WATER HEATER TANK
CAUTION - CHEMICAL
BURN HAZARD
1. Disconnect brewer form the electrical supply. Turn off
the water supply and disconnect water supply from the
brewer inlet fitting.
De-liming chemicals are caustic.
Wear appropriate protective gloves
and goggles during this procedure.
2. Remove the top panel or top warmer section to gain
access to internal components.
3. Disconnect water level sensor and water temperature
sensor from the controller. On 120V units, slip hi-limit
thermostat from under its holder clip. Disassemble the
three lid clips and lift the lid off of the water tank. Store
lid assembly in a safe location.
CAUTION - CHEMICAL
BURN HAZARD
Never siphon de-liming chemicals
or solutions by mouth.
This operation must only be
performed by qualified and
experienced service personnel.
4. Mix de-liming solution according to the manufacturer’s
directions. Add the de-liming solution to the water tank.
Set lid assembly back on tank. Allow to sit for 30
minutes, or as directed by the manufacturer.
5. At end of soaking period, remove lid assembly from tank.
Thoroughly rinse interior components of lid assembly
with clear water. Wipe temperature sensor and water
level sensor with a clean, soft cloth. Store lid assembly
in a safe location.
IMPORTANT: DO NOT spill,
splash or pour water or de-liming
solution into or over any internal
component other than the inside of
the water tank.
6. Using a stiff bristle brush, scrub the coils of the heating
element and the interior surfaces of the water tank.
IMPORTANT: DO NOT allow any
internal components to come into
contact with the de-liming solution.
Take care to keep all internal
components dry.
7. Siphon the used solution and loose lime/scale into an
appropriate container. Dispose of the used solution as
required by local ordinances.
CAUTION: Never siphon by mouth. Serious injury can
result!
NOTE: Repeat steps 4 thru 7 as
required to remove all scale and
lime build-up.
8. Fill the water tank with clean tap water. Rinse
thoroughly, then siphon the rinse water into an
appropriate container for disposal. Again, take care to
keep all internal components dry.
NOTE: Normally, silicone hoses
do not need to be de-limed.
Should de-liming hoses become
necessary, Bloomfield Industries
recommends replacing the hoses.
9. Reassemble the tank lid to the water tank. Make sure
the gasket is properly attached to the lid before
assembling the lid clips. Re-connect the water level and
temperature probes, then reinstall the hi-limit thermostat
(if removed). Verify that all internal components are dry,
then reinstall the top panel.
10. Reconnect brewer to water and electrical. Run and
discard at least three full decanters from the faucet.
Install the brew chamber without filter paper or grounds,
then run and discard at least three full decanters as
normal brew.
11. Brewer is ready to use.

TROUBLESHOOTING SUGGESTIONS
If the E-Max™ goes into the error diagnostic mode as outlined below, it will likely be necessary to
reset the brewer in order to test individual components. Note the reset procedure below:
*
For the first four error modes, press and hold CANCEL for 3 seconds, or RE-ENERGIZE the
brewer by disconnecting from electric power for 5 seconds, then reconnecting.
From “VALVE FAULT”, the brewer must be RE-ENERGIZED! Using the CANCEL button will not
reset the brewer from “Valve Fault”.
*
The Test Program will also assist in isolating and testing specific components. As an example to test
the three main components in the heater system, go to the test program and proceed to turn the
“heater on”. Use a meter or test light to determine if power is getting to and from: the triac, the high
limit and the element.
SUGGESTIONS FOR REMEDIAL ACTION
ERROR MESSAGE CAUSE
1. Temp Probe may not be connected properly, or may be defective. CHECK &
CORRECT. To test probe, go to Test Program and view probe value. A value
of over 155 indicates a defective probe; a value of under 15 indicates a bad
connection of the probe to the board. With an ohmmeter measure resistance of

3. Heating element defective. CHECK ELEMENT; REPLACE IF DEFECTIVE.
4. Hi-limit thermostat may be cutting out at too low a temperature. CHECK HI-
LIMIT THERMOSTAT; REPLACE IF DEFECTIVE. (Note; hi-limit will reset
itself if allowed to cool by 30ºF, making troubleshooting a challenge as the brewer
cools then functions normally.)
