Solenoid Valve
To adjust the water pressure lift the orange Range
Adjustment Knob upward, turn counterclockwise (-) to
decrease pressure and clockwise (+) to increase the
pressure. Snap the orange knob back down after adjusting.
In the event that maintenance is required on the reducing
valve, close the isolating valve prior to the reducer before
performing any maintenance. Use a wrench to unscrew the
Pressure Reducing
Cartridge. Remove
the cartridge by
pulling straight up. Clean cartridge with cold water only.
Clean and/or replace the Strainer Screen before re-
installing the cartridge. Screw the cartridge back into the
Valve Body and re-tighten to the following torque: 10
lb/ft. Be careful not to over tighten the cartridge and risk
cracking the valve body.
5.2.6 Solenoid Maintenance
The water solenoid valve controls the flow of water
through the EVOLUTION. It is a positive shutoff
valve, controlled by the electromagnetic coil on the
valve. Once power has been applied to the coil the
valve will allow water to flow thru the unit and out
the wash gun hose and wash gun, providing the push
button has been pushed on the wash gun. Once power has been removed the solenoid will
close and no water will flow. In the event that water continues to come out the wash gun after
the solenoid has been de-activated there is a good chance that trash in the valve is preventing it
from completely closing. This can be caused by improper clean up from plumbing connections,
trash in the system, or most likely a build-up of calcium deposits from “hard water”. The
following procedures will lead you through correcting this problem.
1. Remove the coil from the valve by loosening the screw on top of the coil.
2. Remove the stem by loosening the large brass
nut on the solenoid body.
3. Once you have the nut loose, then carefully pull
on the stem to remove the plunger. Place hand
under valve to catch any falling parts.
4. As you will see on the plunger it is shaped with a point. The point
goes into the seat and seals off the pressure on the valve. Clean any
debris from the seat and point on the plunger.
