7.9 Maintenance Menu
The MAINTENANCE MENU has three sections to choose from (
Figure 7.11
): PURGE/FILL/DRAIN BARREL, WATER AND
BRIX CALIBRATION, and LINE VOLTAGE CALIBRATION.
PURGE/FILL/DRAIN BARREL (
Figure 7.12
) – 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 it with gas. Use this process before filling the barrel. If the air
is not replaced with gas, then the drink quality of the first few drinks from the barrel will be negatively affected.
The process will fill the barrel with gas three times before automatically ending.
•
DRAIN BARREL: This process will assist in draining liquid from a 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.
