Removal and Installation
Solution Solenoid
The solution solenoid is located in the center of
the scrub deck on the rearward side of the deck.
If the purpose for servicing the solenoid is to
clean the valve seat, you may choose to separate
the top and bottom while still in the machine, as
described in step 5.
1. Close the manual shutoff valve located at the
front-right side of the solution tank.
2. Disconnect the electrical connector (B) from
the top of the solenoid.
3. Loosen the hose clamp (C) and remove the
solution supply hose (D) from the solenoid
inlet.
4. Loosen the nut (E) that secure the solenoid
to the scrub deck frame, and lift the solenoid
upward to remove it from the outlet hose (F).
5. If necessary, separate the upper and lower halves of the solution solenoid by twisting the upper half
counterclockwise. This permits cleaning of the valve seat.
