HOW TO CALIBRATE SPRAYHEAD FLOW RATE
This function allows the operator to test and enter the actual flow rate of water coming out of the sprayhead(s).
The procedure includes a 1-minute dispense of hot water to determine the actual flow rate. Ensure that the brewer
is heated to brewing temperature before performing a sprayhead calibration.
1. Place a container, accurately graduated with a minimum capacity of 60 ounces, under the funnel.
2. Touch the BUNN logo for 2 seconds to enter SERVICE ACCESS.
3. Select the ADVANCED icon.
4. At the PASSWORD ENTRY screen, select ENTER. (If a password is required, enter the code at this screen).
5. At the SERVICE MENU screen, select the CALIBRATION icon.
6. For Single ITCB models, there is only 1 sprayhead to calibrate. For Twin ITCB models, there is a left and a
right sprayhead to calibrate. Ensure the container is under the correct sprayhead for calibration.
7. Select the START button to begin a 1-minute dispense of hot water from the sprayhead.
8. The display will show the time remaining for dispense along with the option to stop the dispense if necessary.
The 60-second timer on the display will count down to zero.
9. When the counter reaches zero, measure the amount of water in the container and select the white text area
on the screen to enter the value to match the amount in the container.
10. Select SAVE. The display should now show the actual flow rate of the sprayhead.
11. Repeat steps 1-7 to calibrate the other side. (Twin ITCB models only)
