AUTOMATIC WATER PURGE MODE
Overview of Purge Mode
When the drain tank fills with water, the upper float triggers a purge cycle, isolating the
vacuum tank from the drain tank, and draining the drain tank. As the water level falls, the
lower float turns the purge cycle off and the system is restored to normal mode.
