full pressure. The pump will automatically turn on
when the pressure decreases.
The Float Shut-Off
-
See Figure 1C
The float shut-off is in the recovery tank. When the liquid

Electric Circuit Locator
See Figure 1H
This unique, patented "smart system", operated by a solid
state circuit, will inform the operator when the two cords
are plugged into separate circuits by illuminating the
"Locator" indicator light. This helps prevent tripping circuit
breakers.
NOTE: Ground plug on the cord is required to allow
circuit locator to operate correctly. The system will
not function without proper ground.
