PULSE BREW AND PRE-INFUSION (continued)

Pulse Feature Operation

Water Outflow (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 final partial

“Pulse Valve On” is required this will also be calculated

automatically.)

The outflow rate of water from the spray head is required to

calculate valve time for different volumes. Spray head outflow

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

156 seconds of the brew valve being open. This is an outflow

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 flow 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:
