Section-10: Alarms
10.1 An Alarm is indicated when the Red LED labeled ‘PRESERVING’ is flashing.
There are two modes of flashing, fast (½ second) and slow (2 seconds).
10.2 Fast flashing indicates that the system is unable to reach the pressurized state.
This can be caused by either a leak or an empty gas tank.
10.3 Slow flashing indicates that the system is unable to release pressure and reach
the unpressurized state. This can be caused by a failure of the vent valve to open.
