IX. Airlock Release Program:
1. If the booster pump is running for more than two minutes, but the float switch does not
become engaged, the sparkling water reservoir will become airlocked with CO
2
. This is
caused by continuously pressing the dispense button with no water available, or if the
dispenser is improperly setup. The dispenser will recognize this and activate the Airlock
Release Program.
2. When activated, the green dispense button will continuously flash, indicating that the
dispense function is disabled. Pressing and holding the button for 5 seconds will start the
correction sequence.
3.
The high pressure gas solenoid will close, preventing CO
2
from entering the reservoir.
The dispense solenoid will then open, releasing the high pressure airlock. The booster
pump will engage and water will continue to flow until the reservoir is completely filled
with water.
4. When the float switch is engaged, the program will terminate and the dispenser will return
to normal operating conditions.
