PROGRAMMING - OPERATOR LEVEL 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 filling 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.
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.
PROGRAMMING - OPERATOR LEVEL (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 page 14, Service & Counters Menu.) 13.
PROGRAMMING - ADVANCED ACCESS THE PROGRAMMING MODE 1. Turn the brewer off with the ON/OFF Key. 2. Press and hold the 4th and 6th Keys (from the left) for 3 seconds, until the LCD reads “BREW SETTINGS”. On Decanter brewers the 4th key is MAIN and the 6th key is REAR. On Thermal/Airpot brewers, and on Tea brewers with volume keys, the 4th key is STANDARD Volume and the 6th key is Large Volume.
PROGRAMMING - ADVANCED (continued) 1. Advance through all of the Menus and wraparound to the first MENU again, by continually depressing the 1st key – BREW (MENU). 2.

PROGRAMMING - PROCEDURES Brew Settings The brew temperature cannot be set any higher than 5ºF below the Maximum Water Temperature, which is factory set at 208ºF. This means maximum brew temperature will be 203ºF. Displayed “Brew Volume” shows a calculated value only. The “Valve Time” setting controls actual volume. TEA BREWERS ONLY · “ByPassDelay:” – By Pass Delay Time. This is the number of seconds after the brew has started to delay before allowing the cold water to begin mixing with the hot tea.
PROGRAMMING - PROCEDURES (continued) · · · “After Hours™:” can be turned off by setting to “0”. If this feature is desired, use the 5th or 6th key to select the number of hours of delay after last brew before After Hours™ is activated. “Quality Time:” – Countdown Quality Timer™.
PROGRAMMING - PROCEDURES (continued) Service & Counters Machine Settings Below are the boiling points for selected North American locations, and the recommended Maximum Water Temperature settings for the E-Max™: · “TotalVol:” – Total Volume. Indicates total water volume processed by the brewer. · “Brew Cycs:” – Brew Cycles. Displays total number of brew cycles since last reset. · “FltrLife:” – Filter Life.
PROGRAMMING - PROCEDURES (continued) “Brew Wait:” The Precise Temperature for Brewing™ feature can be overridden by setting Brew Wait to “N” for No. By doing this, the E-Max™ will start a brew whenever the brew switch is depressed. There will be no delay to heat to the proper temperature. This setting is not the recommended. The Brew Wait is factory set at “Y” for yes. In this mode the E-Max™ will only start a brew at the Precise Brew Temperature.
PROGRAMMING - PROCEDURES (continued) Factory Settings · “InflRate:” – Inflow Rate. The inflow rate is factory set at 0.70 gallons per minute. This value is required to calculate the water volume. Generally the 0.70 setting will be quite accurate unless there is unusually low or high water pressure and volume, in which case the Inflow Rate can be changed. · “Calibration”. To access the calibration program press the 4th key when “Calibration” is on the screen.
PROGRAMMING - PROCEDURES (continued) 1. Remove the top cover of the brewer. Identify and locate the vent, or overflow tube. 2. Access the programming mode, go to Factory Settings and then to “InletValvTime:” setting. Set to 25 seconds, press 3rd key to register change in memory, then 2nd key to exit programming mode. 3. Turn brewer on. 4. Place empty decanter (or airpot/thermal server) under the brew basket. 5. Place empty decanter or other vessel under the faucet and begin drawing water from the faucet.
PROGRAMMING - PROCEDURES (continued) Calibration The probe has been factory calibrated. If a controller board is changed it is recommended that the previous calibration be checked and entered on the new board. However this may not always be possible, or if a new probe is used, calibration should be completed as follows: 1. Turn brewer on and allow to heat to proper temperature, and the heat light will go out. 2. Turn brewer off. 3.
PULSE BREW AND PRE-INFUSION 1. Pre-infuse (or Pre-soak) the Bed of Coffee or Tea. The brew valve can be opened for a short period of time to allow the bed of coffee or tea to be pre-infused. After a delay while the pre-soaking is taking place, the brew valve can be opened to start and complete the brew. Applications 2. Extend Contact Time With the Coffee. The brew valve can be programmed to “pulse” by opening and closing for programmed periods during the brew.
PULSE BREW AND PRE-INFUSION (continued) Pulse Feature Operation The pulse feature will be activated if it has been accessed as above, and values have been programmed into the 3 pulse brew items. When the pulse brew begins, the brew valve will be opened for the number of seconds programmed for “Initial Valve Time” (Init Vlv Time). The valve will then close for the number of seconds in “Pulse Delay”, then open for the number of seconds in “Pulse Valve On”.
