Clean the Screen/Replace the Piston

NOTE: A screen (part of the piston assembly) is provided to keep
debris from clogging the bleed hole. The screen may require
periodic cleaning.
Perform the following steps in order to clean the screen or replace
the piston:
Close the control stop valve (refer to the "Control Stop Valve
Operation" section).
NOTE: If the unit has not flushed since the stop valve was closed,
the inlet arm may still be pressurized. Use the manual flush button
to release pressure.
Use a 3/32" hex wrench to remove the setscrew from the cap.
Remove the cap from the valve body.
Disconnect the DC sensor connector from the solenoid connector
by pulling the connectors apart.
Temporarily store the cap and DC sensor in a safe place.
Use a large adjustable wrench to remove the large retaining nut
from the valve body.
Remove the piston cover by pulling up gently on the solenoid.
Remove the piston from the valve body.
