SCRUBBING SYSTEM OPERATING INSTRUCTIONS
THE SCRUBBING SYSTEM - HOW IT WORKS
There are two scrubbing systems available for the CR 1500 machine, the non-recycling
or standard scrubbing system and the recycling or ESP scrubbing system.
THE NON-RECYCLING OR STANDARD SCRUBBING
SYSTEM - HOW IT WORKS
During the scrubbing process (shown in Figure 13), detergent solution water from the
solution tank is fed to the solution line. There it is fed to the fl oor where three disc
scrubbing brushes work to dislodge soil.
After scrubbing, the dirty solution is vacuumed from the fl oor and discharged into the
containment chamber in the forward portion of the recovery tank, where a system of
baffl es helps to clarify the solution. Sensors in each tank will indicate by lights on the
control panel when the water in the solution tank is too low or when the water in the
recovery tank is too high.
