Calibrating Flow Rate; Enable Brewlogic - Bunn Axiom Series Technical Training Manual

Calibrating Flow Rate

Prior to programming the machine or brewing any coffee a flow rate calibration must be done. Flow rates will vary
from machine to machine, location to location, even from one end of a building to another.
Step 1: Enter Level 2 programming.
Step 2: Scroll to the Calibrate Flow screen. This test is used to capture water from the sprayhead during a pre-deter-
mined 60 second dispense valve cycle.
CALIBRATE FLOW ?
NO
Step 3: Ensure the sprayhead and funnel are in place and put a container, measuring pitcher or server, underneath
the funnel, select Yes.
CONTAINER RDY ?
QUIT
Step 4: To activate the flow rate check, press the Brew button.
Step 5: The valve will open for 60 seconds. Once all of the water has dripped out, use the (-) or (+) buttons to input
the volume collected and select Done.
ENTER OZ:
(-) DONE
It is very important to be accurate when performing this test as it will control the pot level during normal operation.

(Optional)
®
BrewLOGIC is a system that monitors output of water flow from the tank. This can be helpful when the equipment
®
is placed in a high lime environment. As the flow rate begins to slow the system will compensate by increasing brew
times as needed to maintain the proper pot levels. If enabled, the Calibrate Flow screen will not be visible.
Step 1: Ensure the brewer is in it's final location and is level.
Step 2: Enter Level 2 programming.
Step 3: Scroll to Enable BrewLOGIC
