Solution System

Functional Description

The Solution System is a gravity-feed system that supplies cleaning solution to the scrub brush/pad on the
scrub deck. The Solution Solenoid Valve controls the solution flow to the scrub deck. The A1 Control Board
sends a pulsed voltage signal to the Solution Solenoid Valve that opens and closes the Valve to regulate the
solution flow according to the flow rate selected with the solution flow adjustment switch.
The Solution System includes the Solution Tank, Water Filter, Solution Solenoid Valve Assembly and
associated valves and hoses.
