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.  
4
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.

SUPPLY  
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.  
ELECTRICIAN’S INSTALLATION INSTRUCTIONS  
REFER TO ELECTRICAL SPECIFICATIONS - Page 1  
IMPORTANT:  
Before connecting to electricity,  
make sure the E-Max™ has

NOTE: Models 2012 & 2072 require a 115 - 125 V 15A circuit  
(50/60 Hz, 2 wire plus earth ground, with  
IMPORTANT:  
NEMA 5-15R or 5-20R Receptacle)  
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.  
Models 2016 & 2074 require a 120/240V 20A circuit  
(50/60 Hz, 2 hot legs / 1 neutral leg, plus earth ground).

1. Energizing the Brewer: When electricity has been connected to  
the unit, there will be a momentary flash of the power light. Turn  
the brewer on by pressing the POWER key. The  
brewer will start to fill the tank. With the proper  
water supply the tank should be filled in about 2½  
minutes. Once filled, the heating element will come  
on until the proper tank temperature has been  
reached, (which will take about 20 minutes on  
120-Volt models or about 12 minutes on 120/240  
Volt models).  
tested and set at the factory  
If programming adjust-  
ments are necessary,  
refer to the E-Max™  
Programming Manual  
(p/n/73674).  
.
To over-ride the Brew  
Wait mode, press and  
hold the BREW key for  
3 seconds when the  
brewer is in Brew Wait  
mode (i.e. when brew light  
is flashing). The brew will  
proceed immediately  
regardless of water  
2. Brewing (Precise Temperature for Brewing™ — PTB™): In the  
regular operating mode, the E-Max™ maintains the tank  
temperature within +/- 1ºF of the brew temperature.  
Normally this will mean that a brew will be started  
as soon as the BREW key is pressed. However,  
there may be a slight delay if the BREW key is  
pressed immediately after a brew has been  
temperature. This feature  
should only be used when  
testing water volume,  
otherwise the brew will  
proceed with the water  
below the precise brew  
temperature.  
completed (notably on 120 volt models). If the tank  
temperature is below the brew temperature, the  
brew will be delayed, going into the “Brew Wait”  
mode, with the brew light flashing. As soon as the  
correct temperature is reached the brew will  
commence with the brew light on continuously during the brew. When  
the brew begins the main warming station will be turned on  
automatically (if it is not already on). During the brew cycle, if the  
BREW key is pressed, it will be ignored. Only when the brew is  
complete can another brew be started.  
Note: the following  
safety features have been  
incorporated to prevent  
multiple unattended  
brews:  
3. Brew Cancel: To cancel a brew in progress, press the CANCEL  
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  
returns the brewer to normal operation.

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  
3 seconds (i.e. Volume #1 64 oz)., and then the day and time will be displayed.  
7. Changing Brew Volume: As outlined above, display the current brew volume and, before the  
display changes to day and time, depress the CANCEL key momentarily, (not for 3 seconds).  
The next programmed brew volume (e.g. Volume#2 32 oz.) will be displayed on the LCD for  
3 seconds, after which the display will return to the day and time. Repeatedly press CANCEL  
while programmed volumes are shown to view all brew volumes. (If there is only one brew  
volume programmed, only that volume will be displayed.) The last brew volume displayed, before  
the LCD returns to the day and time, is the brew volume that the E-Max™ will brew the next time  
the BREW switch is depressed. When a brew volume other than the 1st brew volume is  
selected, the E-Max™ will complete the brew then return to the 1st or standard brew volume  
automatically.

OPERATION (continued)  
8. Clock  
A. Time – Battery Backup. The E-Max™ has a battery backup system which will maintain the  
proper time during power failures, or when the brewer is unplugged (even for very prolonged  
periods of time). Normally there will not be a need to set the time except for Daylight Saving  
Time changes, or moving the brewer to different time zones.  
B. Changing Day and Time: To change time, turn the E-Max™ off. Press the 2nd key twice  
followed by the 1st key twice to access the time change mode, (i.e. press CANCEL, CANCEL,  
BREW, BREW). In the time change mode the screen will read “Day:” followed by the current  
day setting. Use the 6th key to advance the day, or the 5th key to reverse. When day has  
been properly set, press the 3rd key. The screen will now read “Time:” with the set time on  
the screen, the hour and am or pm flashing. Use the 5th key to go back or the 6th key to  
advance the hour, making sure that the am or pm is correct. When the hour and am/pm is  
correctly set, press the 3rd key, and the screen will read “Time:” with the set time on the  
screen, minutes flashing. As previously use the 5th or 6th keys to adjust the minutes, and  
press the 3rd key when complete. The E-Max will return to the off mode. (Changing time can  
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.

OPERATION (continued)  
12. View Filter Statistics: To view filter statistics, turn the brewer off. Press and hold the 1st key  
(Brew), and depress the 3rd (ON/OFF) key. Total water volume will be displayed (TotalVol.).  
Press the 3rd key to view the Filter Life (FltrLife:). Press the 3rd key to view the percentage of  
the filter that has been used. (If the filter option is used, the filter life volume needs to be entered  
in the program – see E-Max™ Programming Manual, Service & Counters Menu.)  
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).

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
