OPERATION
OPERATING INSTRUCTIONS
IMPORTANT:
All E-Max™ brewers are tested and set at the factory. If programming adjustments are necessary, refer to the appropriate section of this manual.
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 temperature. This feature should only be used when testing water volume, otherwise the brew will proceed with the water below the precise brew temperature.
Note: the following safety features have been incorporated to prevent multiple unattended brews:
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.
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).
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 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.
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.
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.

|
|
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 brewer 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 brewer has the timer setting ON and |
| <![if ! IE]> <![endif]>Manual |
|
power is disconnected, the brewer will start up in the mode that it should be in at the time the |
|
power is restored. |
|
|
|
|
| <![if ! IE]> <![endif]>Programming |
6. Viewing Programmed Brew Volume: (Airpot & Thermal Brewers Only) The brewer can have |
|
|
up to 4 different brew volumes. When a volume other than the standard, or first brew volume, is |
|
|
|
|
|
|
selected, the brewer will complete that volume and then automatically reset to the standard, or |
|
|
first brew volume. With the brewer ON, press and hold the 2nd key. The 1st, or standard, |
| <![if ! IE]> <![endif]>E-Max™ |
|
volume will be displayed for 3 seconds (i.e. Volume #1 64 oz)., followed by the day and time. |
7. Changing Brew Volume: (Airpot & Thermal Brewers Only) As outlined above, display the |
||
|
current brew volume and, before the display changes to day and time, depress the 2nd key |
|
| <![if ! IE]> <![endif]>73674 |
|
momentarily, (not for 3 seconds). The next programmed brew volume (e.g. Volume#2 32 oz.) |
|
will be displayed for 3 seconds, after which the display will return to the day and time. Repeatedly |
|
| <![if ! IE]> <![endif]>p/n |
|
press the 2nd key 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 |
|
| <![if ! IE]> <![endif]>654 |
|
displayed, before the LCD returns to the day and time, is the brew volume that the brewer will |
|
|
brew the next time the BREW switch is depressed. When a brew volume other than the 1st brew |
volume is selected, the brewer will complete the brew then return to the 1st or standard brew volume automatically.

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 page 13 “Time Functions” 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 page 13 “Time Functions” 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 |
<![if ! IE]> <![endif]>Manual |
|
re-start the countdown time. |
|
|
remains on. Push the warmer plate switch to turn the warmer off, and switching it again will |

|
Pulse or Pre-Infusion Volume Options: To set these features, refer to page 19, “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 |
|
11. |
Keypadlock™: This feature is OFF in the standard factory settings. To set the feature refer to |
<![if ! IE]> <![endif]>-Max™ |
|
page 14, “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 pressed). |
<![if ! IE]> <![endif]>E |
|
<![if ! IE]> <![endif]>73674 |
|
|
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 |
<![if ! IE]> <![endif]>p/n |
|
automatically return to keypadlock™ mode. If a brew is not initiated 60 seconds after “unlocking”, |
<![if ! IE]> <![endif]>654 |
|
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 the 2nd key 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 the 2nd key 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 the 2nd key 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 the 2nd key for 3 seconds, or |
|
| <![if ! IE]> <![endif]>Manual |
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). |
||
| <![if ! IE]> <![endif]>Programming |
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 the 2nd key for 3 seconds, |
|
| <![if ! IE]> <![endif]>Max™- |
or re-energize the brewer. (Possible causes of the problem are: no incoming water; slow flow |
|
of incoming water, sensor not reading, etc.). |
||
| <![if ! IE]> <![endif]>E |
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 |
||
| <![if ! IE]> <![endif]>73674 |
||
problem re-occurs this indicates a defective switch on the key pad. |
||
|
and hold the 2nd key for 3 seconds to reset the brewer (or re-energize the brewer). If the |
|
| <![if ! IE]> <![endif]>p/n |
F. “Valve Fault”- Faulty Valve Detection: When an electric or switching problem is detected |
|
| <![if ! IE]> <![endif]>654 |
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 the 2nd key for 3 seconds will not reset a valve fault). |
