Float Cage and Ball
A shutoff Float Cage and Ball prevent the Recovery Tank from being overlled and stops any water from being
sucked into the Vacuum Motor. When the Float Ball rises (to full-tank level) it will seat itself inside the Cage
assembly and block off the Vacuum Motor airow. This causes a reduced Vacuum Motor current load which is
sensed by the A2 control board which automatically shuts off the vacuum and scrub systems.
The LCD will then display the recovery tank full indicator
icon to alert the operator that the recovery tank needs to
be drained.
