10.9 Maintenance Menu
NF*
The MAINTENANCE MENU has two sections to choose from (Figure 10.10):
• PURGE/FILL/DRAIN BARREL
• WATER AND BRIX CALIBRATION
PURGE/FILL/DRAIN BARREL (Figure 10.11) – Provides three semi-automatic routines that eliminate the need to manually
turn solenoids on and off. Follow the on-screen prompts to complete each process. All processes may be terminated at
any time by pressing the END button.
• GAS PURGE: This procedure must be used after the faceplate has been removed and there is air in the barrel.
It will purge the air from the barrel and replace with CO. Use this process before filling the barrel. If the air is
not replaced with CO in the barrel, then the drink quality of the first few drinks from the barrel will be negatively
affected. The process will fill the barrel with CO three times before automatically ending.
• DRAIN BARREL: This process will assist in draining a liquid barrel (defrost first if needed). The user must
terminate this process by pressing the END button once the barrel is empty.
• FILL BARREL: This process fills the barrel with product. The user must terminate this process by pressing the
END button once the barrel is full.
WATER AND BRIX CALIBRATION (Figure 10.12) – Provides a step-by-step process for calibrating the flow controls for the
solution modules. Images and instructions are provided in each step.
