Water Temperature Adjustment
Brew water temperature can be adjusted by turning the knob on the main controller located behind the controller
access panel. Temperature adjustment range is 175
o
F - 202
o
F. Adjustment for temperature should be made after
measuring the temperature of the water dispensed from the sprayhead by the following procedure:
1) Remove the sprayhead from the brewer and set aside.
2) Place a shuttle without the lid under the outlet.
3) Press Start and, using a thermometer, measure the temperature of the water being dispensed.
4) If a higher temperature is desired, rotate the Temperature Adjustment knob clockwise. If a lower temperature is
desired, rotate the Temperature Adjustment knob counter-clockwise.
5) If water temperature setting has been increased, wait until heater has cycled and then follow steps 3 and 4
again. If water temperature setting has been decreased, brew a large portion of water and repeat steps 3 and 4.
6) Continue this procedure until desired brew temperature is achieved.
7) Replace sprayhead.
Brew Timing/Brew Volume Adjustment
Brew volume is adjusted by adjusting the timer values of the controller (refer to
Temperature and Timing Controls
section
).
Before adjusting brew timing, brew a batch of water and measure the brew volume. Record this value.
To adjust brew timing:
1) Remove the controller access panel.
2) Slide the brewer selector switch to the appropriate position.
3) Press the Select button momentarily; a LED will light up to indicate which timing selection is being displayed on
the alphanumeric display. Scroll down the selection list to the timer to be adjusted. Note the timer value displayed.
The new timing should be calculated by the following:
Desired brew volume
Desired brew time =
—————————— X
Current brew time
Current brew volume
4) After selecting the appropriate side and portion timer, adjust the timer value to the desired value by pressing the
Up or Down buttons on the controller. Increasing the timer value increases the brew dispensing time; decreas-
ing the number decreases the time. Hold down the Up or Down button to scroll quickly to the desired value.
Once the desired value is displayed, then press the Select button on the controller to save this new value.
5) Brew a batch of water and measure volume dispensed. Repeat procedure as necessary until desired volume is
dispensed.
6) Replace the access panel.
