Internal Brixing System Brix Adjustment Instructions

1.Apply power to machine and turn on by pressing the power button.

2.Enter the display menu by pressing the “Gourmet” button for about 5 seconds. Press and release “Gourmet” button to step through the menu to the “Test Refill” screen. Press and release the “Ice” button to select YES.

3.The Activate Valve screen will allow you to test the pumping and refill circuit. Press and hold the ULTRA button to activate the left refill system. Confirm that the left side is filling when the ULTRA button is pressed. Release the ULTRA button to stop the filling process. Repeat this process for the right side by pressing the ICE button to test. Check for leaks at the hoses while pumping system is running.

4.Run each side until water and product are flowing freely.

5.Take a sample from each side (directly from the tubes going into the hopper) to check for proper brix ratio.

6.Make adjustments to the brix/ratio by turning the screw/valve adjuster on the water side at the top of the motor cover. Turning the screw clockwise will decrease the water flow. Counter-clockwise will increase the water flow. The flow rate on the syrup side is not adjustable.

7.Once the testing is complete, exit the programming menu.

8.The auto fill feature can be turned on by pressing the auger button for each side until the display reads

“AUGER REFILL ON”.

NOTE: Some models also include a “Delay Refill” option. This feature is used to dose in small amounts of new product while delaying between doses. This can help the already frozen product from becoming deluted and not ready to serve. These delay and fill times are to be determined and set based on each application as desired by the end user.

NOTE: Refill system includes a “Maximum Fill Time” in the software. If the time to fill the hopper exceeds this limit, the hopper lights will flash and a “Refill Fault” will be displayed on the screen. If this accurs, check the product supply to ensure the BIB is not empty. (Change BIB if empty). Then press the “ULTRA” button for 3 seconds to clear the fault and restart the refill system.
