for 3 seconds or unplug power source jack (black wire) at the circuit board and plug back in. This resets the

Drive Cap Assembly, Main Piston and Regenerant Piston
The drive assembly must be removed to access the drive cap assembly. The drive cap assembly must be
removed to access the piston(s). The drive cap assembly is threaded into the control valve body and seals
with an o-ring. To remove the drive cap assembly use the special plastic wrench or insert a ¼” to ½” flat blade
screwdriver into one of the slots around the top 2” of the drive cap assembly so it engages the notches
moulded into the drive back plate around the top 2” of the piston cavity. The notches are visible through the
holes. Lever the screwdriver so the drive cap assembly turns counter clockwise. Once loosened, unscrew the
drive cap assembly by hand and pull straight out.
The drive cap assembly contains the drive cap, the main drive gear, drive cap spline, piston rod and various other parts that should not be
dissembled in the field. The only replaceable part on the drive cap assembly is the o-ring. Attached to the drive cap assembly is the main piston
(downflow) and a regenerant piston.
The regenerant piston (the small diameter one behind the main piston) is removed from the main piston by
pressing sideways and unsnapping it from its latch. Chemically clean in vinegar, or replace the regenerant
piston if needed. To remove the main downflow or upflow piston fully extend the piston rod and then unsnap
the main piston from its latch by pressing on the side with the number. Chemically clean in vinegar, or replace
the main piston.
