ESP SYSTEM OPERATING INSTRUCTIONS
THE RECOVERY OR ESP AND AUTOFIL SYSTEM - HOW IT WORKS
During the scrubbing process, filtered water from the solution tank is fed to the solution line, where it combines with detergent from the metering pump. This mixture is then fed to the floor where three disc scrubbing brushes work to dislodge soil.
After scrubbing, the dirty solution is vacuumed from the floor and discharged into the recovery tank. At inter- vals, a float switch activates the recycling pump, which sends filtered solution from the recovery tank to the solution tank. Detergent is added continuously to solution water from the flow valve.
The autofil system distributes water from the supply hose into the recovery and solution tanks. Then a solenoid valve is closed when the proper level in the solution tank is reached.
NOTE
Both tanks must be drained and cleaned before filling.
