5.3 Water Flow Rate and Brix
The water flow rate and brix for each barrel must be verified and adjusted for optimal performance. Use the following
procedure to adjust the water flow rate and set the brix for each barrel:
For multi-flavor dispensers, the flavor injection modules will also need to be calibrated. Please refer to the Multi-Flavor
Merchandiser Manual (24-M4MF-0001) for the calibration procedure.
The target brix for most sugar flavors is between 13.5 and 15. The target brix for most “light” flavors will be lower, usually
between 9 and 10. Check the specifications for the flavors if unsure of the target brix
Note: Light or diet products have a low brix and can cause problems with the dispenser if not properly set up. Although
these products contain ingredients that ensure the sugars freeze, they can still create excessive ice if not carefully brixed
according to their specifications. Low brix issues will be associated with events such as audible ice scraping during freeze
and low beater error problems.
1 Turn the syrup shuto valve to the OFF position (Figure 5.2).
2
Adjust the water ow rate to 1.5 oz/sec (44.4 ml/sec) by dispensing water from the solution module
through the sample port for 10 seconds into a measuring cup. The amount measured should
be 15 oz (444 ml). Turn the ow control clockwise to increase the ow and counterclockwise to
reduce the ow.
Note: The WATER AND BRIX CALIBRATION screen under the MAINTENANCE MENU can be used to
help with timing.
3
Turn the syrup shuto valve to the ON position and dispense a cup of uid from the sample port
to establish a stable ow.
4
Once a good water and syrup mixture is obtained, dispense a 16 oz sample and measure the
sample brix with a refractometer. Be sure to thoroughly mix the sample rst by pouring back and
fourth between two cups.
5
Turn the syrup ow control counterclockwise to decrease the brix. Turn the syrup ow control
clockwise to increase the brix.
6 Dispense and discard several samples after adjusting the brix.
