PULSE BREW SETUP PROCEDURE
The pulse brew parameters (initial fill time, off times, and remaining on times) are entered using the following set-
by-example process.
1. First set the brew volume using the standard procedure in
Brew Volume Setup.
2. Position an empty container under the sprayhead. Allow the tank to finish refilling. Make sure that the READY
lamp is on, or that the BREW LOCKOUT function is turned off.
3. Press and hold the "ON/OFF" button. The brew valve will turn on after 10 seconds. Release the button. This
begins the initial on-time setting. When the spray has continued for the desired time, momentarily press the
"ON/OFF" button.
4. The spray is now stopped and the off time setting has begun. Press the "ON/OFF" button momentarily to end
the off time .
5. The spray is now on again and the remaining on time setting has begun. Press the "ON/OFF" button
momentarily at the end of the desired remaining on time .
6. The setup is now complete and the parameters are stored in memory. The spray will continue the off and on
cycles until the brew volume of step 1 is complete. Pressing the "ON/OFF" button again will terminate the
brewing cycle, with the parameters stored in memory.
7. If only a preinfusion is desired, i.e. an initial on time followed by one off period, use the same procedure, but
stop after step 4 and allow the brew to finish the volume set in step 1. This will store the initial on time and off
time in memory.
Procedure for Disabling Pulse Brew or Preinfusion:
1. Position an empty container under the sprayhead. Allow the tank to finish refilling. Make sure that the READY
lamp is on, or that the BREW LOCKOUT function is turned off.
2. Press and hold the "ON/OFF" button. The brew valve will turn on after 10 seconds. Release the button.
3. Allow the spray to continue and press no buttons until spray stops. The pulse and preinfusion functions are
now disabled.
NOTE: When the brewer has been set up for pulse or preinfusion, the adjustment of brew volume is done the same
as always and has no effect on the pulse brew parameters. The pulsing is temporarily disabled while adjusting the
brew volume and automatically returns during normal brewing.
