STARTING FCB AND ADJUSTING WATER-TO-SYRUP “RATIO” (BRIX) OF DISPENSED PRODUCT

1.Open shutoff valve in city plain water line connected to the Unit. Check for water leaks and tighten or repair

leaks if evident. ‘‘H2O OUT’’ fault message should have gone out but ‘‘SYRUP 1’’, and ‘‘SYRUP 2’’ fault mes- sages will continue to be displayed.

IMPORTANT: Product shutoff valves, located in lines leading from product blender tanks to freeze cylinders (see Figure 2 and 6), must be closed at this time. Closing valves prevents product from filling freeze cylinders while checking BRIX of product in product blender tanks.

2.Close product shutoff valves, located in lines leading from product blender tanks to freeze cylinders, to pre- vent product from entering cylinders.

IMPORTANT: The following CO2 and liquid disconnects disconnecting and connecting procedure for soft drink tank replacement or filling soft drink tank in place must be performed in order as follows:

To disconnect soft drink tank from Unit syrup system.

A.Disconnect liquid disconnect from soft drink tank. NOTE – Disconnecting liquid quick disconnect from soft drink tank first prevents syrup from backflowing through Unit syrup flow regulator which may alter regulator adjustment.

B.Second, disconnect CO2 quick disconnect from soft drink tank.

To connect soft drink tank into Unit syrup system.

A.First, connect CO2 quick disconnect to soft drink tank to pressurize the tank.

B.Second, connect liquid quick disconnect to the soft drink tank.

3.Pressurize soft drink tanks containing syrup, then connect tanks into Unit syrup systems.“OFF 1”, “OFF 2”, “SYRUP 1”, and “SYRUP 2” fault messages will continue to be displayed.

4.The following steps A through J are instructions for adjusting the Water-to-Syrup “Ratio” (BRIX) of the dispensed product on one of the systems.

NOTE: The Unit control panel assembly is equipped with a hidden “SECURITY SWITCH” located be- tween “FILL 1” and “ERROR RESET” control switches (see Figure 3). Pressing in and holding the “SECURITY SWITCH” for 3 seconds deactivates the control switches preventing tampering with Unit normal operation. To reactivate the control switches, press in and hold the “SECURITY SWITCH” for 3 seconds.

NOTE: The adjustable carbonated water flow regulators (see Figure 2 and 12) located in their respective systems, control carbonated water flow rate to the product blender tanks. The water flow regulators are factory adjusted at 1.3 ￿ 0.05 oz/second and should not normally require adjustment. If adjustment is necessary, adjust as instructed.

A.Press ‘‘FILL 1’’ switch to fill No. 1 syrup system sold-out float. ‘‘SYRUP 1’’ fault message will go out and ‘‘FILL 1’’ fault message will come on. ‘‘OFF 1’’, ‘‘OFF 2’’, and ‘‘SYRUP 2’’ fault messages will continue to be displayed.
