Brew at Temperature
Ideal brew water temperature is 200°F/93°C. After brewing, brewers can take time to
recover the hot water tank temperature and signal READY to brew. This is called
“recovery time”. The lag in recovery time is caused by rapid brewing cycles in a rush, low
power heating elements, low incoming electrical voltage, water supply temperature, even
the barometric pressure.
Operators will adjust the “Brew At” temperature to allow the brewing at lower
temperatures. This will allow a slightly faster recovery time and give a small increase in
brew cycles per hour.
Reduced brew temperature will always compromise the quality of the finished brew and
lower the temperature of the customers coffee.

How to calibrate the flow rate
Set the flow rates of the brewer valves to adjust for over or under potting.
Built-in algorithms in brewer controller software corrects brew parameter to customer preferences or to trim variations in flow control components
The control software uses the new flow rate entered in the CALIBRATION screen to adjust and correct the amount of water delivered by the valve
Increasing the flow rate value DECREASES the volume of brew water dispensed
Decreasing the flow rate value INCREASES the volume of brew water dispensed
Flow rate adjustment will control all batches made by the valve. All batches on the side of the valve will be adjusted, (left or right)
-Obtain the VOLUME DISPENSED of water only, by brewing a batch without coffee or filter paper.
-Obtain the PROGAMMED VALUE of the same brew. This is displayed on the home screen in the batch box
-Obtain the CURRENT SETTING for the flow rate from the brewer. Do this by entering PROGRAMMING and
Tap to “CALIBRATION” then, tap “Flow Rates” and then “Water Valves”. The valves f
low rate is in the top right corner.
Using the values obtained above to obtain the new flow rate setting to correct the volume dispensed:
Divide the volume dispensed by the programmed volume and then multiply by the current setting
VOLUME DISPENSED
PROGRAMMED VALUE ×CURRENT SETTING
=
NEW FLOW RATE SETTING
-Enter programming mode, tap to “CALIBRATION”
-Tap back to “Flow Rates” and then to “Water Valves”
-Enter the new flow rate into the calibration slider for the valve tested
Note: values for brewers set in gallons are in decimal format. Place all quantities in ounces and divide by 128 (One gallon =128 ounces)
to obtain decimal format 3 quarts delivered=96oz, 96oz÷128=0.75 gal.
