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

ashing). 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.

1. Energizing the Brewer: When electricity has been connected to

the unit, there will be a momentary ash of the power light. Turn

the brewer on by pressing the POWER key. The

brewer will start to ll the tank. With the proper water supply the tank should be lled in about 2½ minutes. Once lled, 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 ashing. 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:

The brew key is disabled during a brew cycle. This minimizes the possibility of double brewing.

When the “Brew” light is

on or ashing, 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.

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 owing 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.

PROGRAMMING FEATURES AND OPTIONS

1. View Water Temperature in Tank: To view the water temperature on the screen, the brewer

brewer must be ON, and not brewing or in the lling mode. Press and hold the 4th key, and

depress the 6th key. The actual water temperature will be displayed for 3 seconds.

2. Daily Brew Count: The brewer maintains a count of the number of completed brews for a 7-day period. To access the count, turn the brewer OFF by pressing the 3rd key. In the OFF mode, press and hold the 2nd (CANCEL) key for 3 seconds. The current day and brew count will be displayed. Depress the 3rd key repeatedly to view each preceding day. When all 7 days have been displayed a 7-day total will be displayed. If you wish to exit the daily brew count before viewing all of the days, press the 2nd key.

3. ON/OFF – Non Automatic Timer: To turn the brewer OFF, press the 3rd key (ON/OFF ): 2 beeps will be heard and the brewer will be turned OFF, indicated by all lights being off, (including any warmer plates on decanter brewers). To turn the brewer ON, press the 3rd key: 2 beeps will

sound, all lights will ash once, then the “Power” light will remain on, (the “Heat” light may come on if

water temperature is too low).

4. ON/OFF – Automatic Timer Feature: The factory programmed brewer has the automatic timer turned off. To set the automatic timer, refer to page 13, “Time Functions” Menu. If the Automatic Timer feature is programmed off, the brewer can be turned on and off by depressing the 3rd (ON/OFF) key, as noted above.

* When the Automatic Timer feature is programmed ON, the brewer will turn on and off

automatically, at a programmed time, Monday to Friday; with a separate on and off programmed time schedule for Saturday and Sunday.

* Temporarily Overriding the Automatic ON/OFF function. While in the automatic timed OFF

mode the brewer can be started by depressing the 3rd (ON/OFF) key. 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 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 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: (Airpot & Thermal Brewers Only) The brewer can have

up to 4 different brew volumes. When a volume other than the standard, or rst brew volume, is selected, the brewer will complete that volume and then automatically reset to the standard, or rst

brew volume. With the brewer ON, press and hold the 2nd key. The 1st, or standard, 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 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 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 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.

PROGRAMMING - OPERATOR LEVEL (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 ashing. 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 ashing. 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 reheat less frequently – this feature saves energy and extend component life. While in the After Hours mode, the power light will ash 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 ash 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 ash continuously until reset. While the light is ashing 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 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 that the second programmed brew volume has utilized the pulse or preinfusion program options.

11. Keypadlock™: This feature is OFF in the standard factory settings. To set the feature refer to 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). 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.

12. View Filter Statistics: To view lter 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 lter that has been used. (If the lter option is used, the lter life volume needs to be

entered in the program – see page 14, 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, ash 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 ve minute period, the unit will go

into the Over Temperature Mode with all lights ashing. When in this mode the brewer turns off the heating elements, the solenoid valves are turned off; the switches disabled; (and all lights ashing 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 ashing, 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 lling for the rst time, the inlet valve

will remain open for 4¼ minutes, (the screen will read “lling…”). 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 ash alternately with the

Heat light, until the brewer is reset. To reset press and hold the 2nd key for 3 seconds, or

re-energize the brewer. (Possible causes of the problem are: no incoming water; slow ow 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 the 2nd key for 3

or re-energize the brewer. (Possible causes of the problem are: no incoming water; slow ow

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 ash alternately and the brewer will turn off all valves and elements. Press and

hold the 2nd 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,
