Solution System
Functional Description
The solution system supplies the detergent to the brush when cleaning the oor. 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 detergent quantity is adjusted by the operator with the solution ow switch (SW3). The solution ows
from the tank to the tap, through the lter and solenoid valve (EV) and then to the brush deck.
The solenoid valve (EV) is driven by the program selection knob/rotary switch (SW1) when it is turned to 1 or
2, and the machine start-up enabling push-button (SW2).
When the solution ow switch (SW3) is open the solenoid valve (EV) is driven by solenoid valve timer (KT1)
(2 sec. ON - 2 sec. OFF). When the solution ow switch (SW3) is closed the solenoid valve (EV) is always on
(by-pass the solenoid valve timer).
The circuit is protected by the function selector fuse (F3) on the LED electronic board (EB1).
The solenoid valve (EV) opening and closing time, according to the water ow, are shown below:
