30 - Solution System
Functional Description
The solution system supplies water and detergent to the brush when cleaning the floor. The solution tank is
also the main machine body There is a manual valve on the left side of the tank to close the water supply
whenever maintenance must be performed on the machine. The solution flows from the tank to the tap,
through the filter and solenoid valve (EV1) and then to the brush deck.
The detergent pump (M4), present only on EcoFlex systems, controls the flow of detergent from the EcoFlex
tank which is then transported to the flow in the main tube just before the solution enters the brush deck.
The EcoFlex system can be selected with the specific button on the User interface controller (EB3).
The quantity of detergent is defined by the operator via the buttons on the User interface controller (EB3).
Solution flow levels 1, 2 and 3 regulate the flow of detergent solution on the basis of the machine speed so as
to keep the quantity of solution dispensed per square metre of floor treated constant (for further details and
modifications, see the corresponding section in the chapter Control System).
Located centrally, below the tank, there is also a hole for draining any liquid in the battery compartment
The solution flow is regulated by various timed ON / OFF cycles, according to:
•
Water flow rate regulation (0 - 4)
• Solution tank level
Both the solenoid valve and detergent pump (when the EcoFlex system is enabled) follow the same timings
The solenoid valve and detergent pump operate only with the following inputs/conditions:
• Brush function on
• Forward paddle pressed
•
Battery level not in condition with flashing segments.
