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 CO2. Use this process before filling the barrel. If the air is
not replaced with CO2 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 CO2 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.
