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.

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,

Time Functions

After Hours™ is an energy saving mode. When After Hours™ is activated, the E-Max™ will allow the water temperature to drop by 20ºF before reheating, and in the case of Decanter Brewers, will turn off any warmer plates that are turned on.

Coffee loses freshness as it sits on the warmer. The Countdown Quality Timer™ provides a visual indication that previously brewed coffee has expired.

The timer will turn the E-Max™ off at the end of the day, and turn it back on so that the brew water will be hot and ready for

the rst brew of the morning.

Time for the E-Max™ is maintained with a battery backup system that will last up to 20 years. This system also

handles power uctuations

by maintaining time settings during power outages. The E-Max™ battery backup system maintains the proper time except while in the Time Functions menu. If a prolonged period of time is spent in this menu, it will be necessary to adjust the time before ending programming.

The day and time can be set without going into the programming mode. See “Changing Day and Time” in the Operator Level section of this manual.

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. If a lter is used input the number of

gallons of capacity, the indicator reports in increments of 100 gallons.

· “Reset Totals:”. To clear out totals for volume and brew

cycles.

· “Srv” – Service Number. Displays the service phone that

will display when a diagnostic message is on the LCD. Can only be loaded with the PC upload/download program.

· “Temp. Unit:” – Temperature Unit. Set to “F” for ºF and

“C” for ºC.

· “Vol. Unit:” – Volume Unit. Set to either “oz” for ounces or

“L” for liters. (For Tea Brewers this is set to gallons.)

· “KeyPadLock:” Turn to “On” or “Off”. If “On” the keypad

switches can only be activated by pressing and holding the CANCEL key for 6 seconds. Then the keypad will be active until a brew has been completed. Or if a brew is not started the keypad will revert to the locked mode after 60 seconds.

· “MaxWt.Temp:” – Maximum Water Temperature. The

maximum water temperature is factory set at 208ºF degrees, but can be adjusted up as high as 210ºF. The brew temperature cannot be set any closer than 5º below the maximum temperature. Maximum temperature should be set at least 2ºF degrees below the boiling point. The E-Max™ will go into the “overheat error” if the water temperature in the tank is sensed to be at or above the Maximum Water Temperature level. Therefore in higher altitude locations, adjust the Maximum Water Temperature down.

See temperature charts, page 15.

· “Mode:” – Operating Mode. Set this to operate as

“Decanter” or “Thermal”.

In “Decanter” mode, the 3 keys on the right operate as

warmer plate switches.

In “Thermal” the 3 keys on the right operate as volume

selection switches.

Tea Brewers are pre-set to tea brewer mode.

· “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.

· “Load Defaults?” Reloading of default settings will reset

many of the programmed settings to those outlined in the programming table. In the table those items with “No Default” noted in the Default column would not be reset when defaults are re-loaded. Where a value is noted, this would be the re-loaded value if defaults are loaded. Re-loading of defaults should be used only if major programming problems have occurred and it is necessary to return to factory settings.

PROGRAMMING - PROCEDURES (continued)

Factory Settings

The factory settings menu can only be accessed by going into the programming mode:

Press and hold the 4th and 6th keys for 3 seconds until the LCD reads “BREW SETTINGS”.

Then, press the 1st key until the LCD reads “MACHINE SETTINGS”; then,

Press and hold the 4th and 6th keys for three seconds until the LCD reads “FACTORY SETTINGS”.

Only qualied personnel should

make changes to these settings.

Timer Status 1: If set to “1” the timer will automatically turn the machine on and off, until the “OFF” key is used to turn it off. The machine will then remain off until it is manually turned on. Timer status 1 should only be used in circumstances where the machine will not get turned off accidentally. (Manual OFF overrides Timer)

Timer Status 2: (Factory Setting.) If set to “2” the timer will automatically turn the machine on and off. If the brewer is turned off manually it will remain off until the next scheduled on time; or if it is turned on manually it will remain on until the next scheduled off time. (Timer overrides manual ON/OFF).

· “InRate:” – Inow Rate. The inow 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 Inow Rate can be changed.

· “Calibration”. To access the calibration program press the

4th key when “Calibration” is on the screen. The probe is factory set and should not need resetting, unless the controller board or probe is changed. See Calibration Instructions following the Factory Settings menu items for detailed instructions.

· “TotalVol:” – Total Volume. Total water volume is stored in

the Factory Settings menu as well as in the Service & Counters menu. This total is not re-settable.

· “BrewCycs:” – Brew Cycles. Total brew cycles is stored in

the Factory Settings menu as well as in the Service & Counters menu. This total is not re-settable.

· “InletValvTime:” – Inlet Valve Time. The inlet valve time

is important to gaining proper brew volume in varying water

pressure and ow conditions. When the water in the tank

drops below the liquid level sensor, the inlet valve will come

on and ll to the sensor (which will take a few seconds due to meniscus) then continue lling for the number of seconds

programmed for the INLET VALVE TIME. The factory setting is 3 seconds that will cover most conditions. However,

if water pressure and ow is low increase the value to 6 or 7 seconds. Conversely if pressure and ow are high decrease

the setting to 1 or 2 seconds. See Adjusting “Inlet Valve Time – Determining Pressure and Flow” below for more details on

how to get the proper setting for specic water conditions.

· “Valve Delay”. The valve delay time is the amount of time to

delay turning on the inlet valve after water has dropped below the liquid level sensor. Factory setting for this is “0” seconds.

· “Timer Status”. If the timer (in the Time Functions Menu) is

on, this setting can be used in two different ways.

654 p/n 73674 E-Max™ Programming Manual

PROGRAMMING - PROCEDURES (continued)

1. Remove the top cover of the brewer. Identify and locate the

vent, or overow 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.

Adjust Inlet Valve Time

Determining Pressure and Flow

NOTE: The following proce-

dure must be performed by a

qualied technician!

This adjustment will help maintain consistent volume in situations where water pres-

sure and ow is exceptionally

high or low. This technique also helps in determining the actual

pressure and ow.

IMPORTANT: DO NOT adjust the inlet valve time if water pressure at this location

uctuates high to low.

6. When the inlet valve comes on, stop drawing water from the faucet, and count the number of seconds before the wa-

ter reaches the vent or overow tube. (The tubing is clear

enough that water will be visible when it starts to go into the vent tube – count the number of seconds to when water is

rst visible at the tube, not when the tube has lled.) Note

the number of seconds the valve was on until water becomes visible at the vent tube.

7. The Inlet Valve Time should be 1/3 to ½ of the number of

seconds in #6 above. As an example, if it took 12 seconds before water was visible at the vent tube, then the Inlet Valve Time should be set between 4 and 6 seconds.

8. Repeat the above if necessary to conrm initial ndings.

9. Turn brewer off, enter programming, then factory settings, and set “InletValvTime” to proper time. Press 3rd key to register change in memory, then 2nd key to exit programming mode.

654 p/n 73674 E-Max™ Programming Manual

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. Access the programming mode, go to Factory Settings, go to Calibration and press the 4th key to access calibration.

4. Using an accurate thermometer, determine the actual tank temperature by measuring the temperature of the water coming out of the faucet. It is important to run the water over the thermostat long enough to get a proper reading. (An alternate method of establishing water temperature is to remove the top cover of the brewer, then pull out the level sensor. Insert the thermometer into the brewer. Allow time for the thermometer temperature to stablize.)

5. Once the actual tank temperature has been established, look at the values on the screen. As an example, it may read “199F Corr. + 0” This would indicate that the water temperature in the tank is 199ºF with no correction (or calibration) of the probe. If the actual temperature according to the thermostat was:

HIGHER by 3ºF (i.e. 202ºF in this example), press the 6th key

3 times until the screen reads as follows: “202F Corr. + 3”.

LOWER by 3ºF (i.e. 196ºF in this example), press the 5th key

3 times until the screen reads as follows: “196F Corr. – 3”.

6. Make sure the temperature on the left of the screen agrees with the actual temperature of the water determined with the accurate thermostat. Once this has been completed the E-Max™ will maintain the calibrated setting.

7. Once calibrated press the 3rd key to continue in the Factory Settings menu, press the 1st key to return to Brew Settings menu, or press the 2nd key to exit programming.

654 p/n 73674 E-Max™ Programming Manual

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.

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. This capability will allow for longer contact with the coffee or tea if higher extraction rates are required.

3. Prevent Brew Basket Overow (or Flooding).

The pulse feature allows the delivery time of the water to be

extended. Overow problems can also be experienced if particularly nd grind coffee is used. The E-Max™ can be

programmed to extend the delivery of the water over a longer

period of time, thus preventing any overow problems.

1. Select the Brew Volume that will be using the “pulse” brew feature. (i.e. go to selected volume — BrewVol1, 2, 3 or 4 in the Brew Settings menus.)

2. With the selected volume on the screen (BrewVolX:), change volume if necessary (must not be “0”) and press the 4th key to go to the Pulse Programming options (as opposed to pressing the 3rd key which would bypass Pulse Programming).

Applications

Access the Pulse Feature

3. The rst three menu items below will appear in this order

(followed by “Total Valve” and “Drip Out Time” which are used for both the pulse and regular brewing mode):

· Init Vlv Time: Initial Valve Time (seconds) to open before

pulse cycle(s) begin.

· Pulse Delay: Number of seconds valve is closed beginning

pulse cycle(s).

· Pulse Valve On: Number of seconds valve is open during

pulse cycle(s).

· Total Valve: Total number of seconds valve is to be open

(pulse + initial).

· Drip Out Time: Time after valve is closed before brew is

complete and all water has dripped out as coffee or tea.

PULSE BREW AND PRE-INFUSION (continued)

Pulse Feature Operation

Water Outow

(Delivery)Rates

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”. The pulse cycle (Pulse Delay plus Pulse Valve) will be repeated continuously until the brew valve has been opened for the “Total Valve” Time. The E-Max™ will calculate the number of seconds for the full brew and display it on the LCD to begin the brew and it will also calculate how

many pulse cycles are required to complete the brew. (If a nal

partial “Pulse Valve On” is required this will also be calculated automatically.)

The outow rate of water from the spray head is required to calculate valve time for different volumes. Spray head outow

rates are based on the standard 64-ounce coffee brew requiring

156 seconds of the brew valve being open. This is an outow

rate of 0.410 ounces per second. To calculate Total Valve time the ounces required should be divided by 0.410 oz/second.

Each brewer may have a slightly different ow rate based on

whether the brewer is level, scale build up on lines, etc. Minor adjustments may be required to get precise volume. Examples of different volumes and valve times are as follows:
