Calibrating Commercial Barista
There is a need to calibrate your machine at your installation. This step lets your machine know what type of water
volume flow is going through your machine at your location. Once this step is done, your machine will program
easier.
To get into calibration mode you need to turn off your machine and hold in the cancel button as you turn on the
machine. Continue to hold the cancel button in till you get past all the flashing lights and beeps, this takes about 5
seconds. Now release the cancel button. Now push and hold the cancel button again for about 15 seconds. After
15 seconds has past you should be able to release the button. This takes you into program mode, but this time you
will have four (4) extra steps.
The program mode will start as always with 1A. To advance past 1A push the cancel button again and you should
see 1B. Pushing your cancel button again will get you to the next four (4) steps, 1C, 1D, 1E,and 1F, which are your
calibration steps. So push your button again and lets get started.
At 1C a two-minute time will be displayed and the Brew 1 button will be lit. This button, when pushed, will begin the
process of calibrating the volume for one dump valve. You will need to capture the water that will be dispensed
when you push the button. You will also need to measure the water that is dispensed. You will get about 2 quarts
(32 ounces) +/- 10 ounces. Be prepared to capture this much water.
At 1D you will record how much water you captured at 1C. If the volume displayed is greater than the volume you
caught, lower it by pressing the Brew 2 button (-). If the displayed volume is less than the captured water, raise the
volume by pressing the Brew 1 button (+). Now the machine is calibrated for dump valve #1, press your cancel
button to move to step 1E.
At 1E a two-minute time will be displayed and the Brew 2 button will be lit. This button, when pushed, will begin the
process of calibrating the volume for dump valve #2. You will need to capture the water that will be dispensed when
you push the button. You will also need to measure the water that is dispensed. You will get about 4 quarts (64
ounces) +/- 10 ounces. Be prepared to capture this much water.
At 1F you will record how much water you captured at 1E. If the volume displayed is greater than the volume you
caught, lower it by pressing the Brew 2 button (-). If the displayed volume is less than the captured water, raise the
volume by pressing the Brew 1 button (+). Be prepared to capture this much water.
Now that machine is calibrated, turn off the machine for 2 seconds and turn it back on. This will get the machine out
of calibration mode allowing no else to get into this program.
To return to calibration mode, just repeat the above steps.
