• Taylor C602 59 Model C602 Systems, Controls and Operations 040608 Syrup Calibration Calibrating the syrup flow should be performed weekly when the syrup system is cleaned. It is vital that the correct amount of syrup be incorporated into the frozen mix to obtain a quality shake. To determine the rate of syrup flow, you will need a calibration cup indicating fluid ounces. The proper rate of syrup flow is 1 fl. oz. (30 ml) of syrup in 5 seconds. For Triple Thick Shake syrups, the proper syrup flow rate is 1 fl. oz. +/- 1/8 fl. oz.
