The regenerant piston (the small diameter one behind the 

main piston) is removed from the main piston by press-

ing sideways and unsnapping it from its latch.  Chemically 

clean this in dilute sodium bisulfite or 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 this in dilute sodium bisulfite or 

vinegar, or replace the main piston.

Reattach the main piston to the drive cap assembly.  Reattach 

the regenerant piston (if needed) to the main piston.  Do not lu-

bricate the piston rod, main piston or regenerant piston.  Lubri-

cant will adversely affect the clear lip seals.  Reinsert the drive 

cap assembly and piston into the spacer stack assembly and 

hand tighten the drive cap assembly.  Continue to tighten the 

drive cap assembly using a screwdriver as a ratchet until the 

black o-ring on the spacer stack assembly is no longer visible 

through the drain port.  Excessive force can break the notches 

molded into the drive back plate.  Make certain that the main 

drive gear still turns freely.  The exact position of the piston is 

not important as long as the main drive gear turns freely.

Reattach the drive assembly to the control valve and connect 

all plugs.  After completing any valve maintenance, press 

and hold NEXT and REGEN buttons for 3 seconds or unplug 

power source jack (black wire) and plug back in.  This resets 

the electronics and establishes the service piston position.  

This display should flash all wording, then flash the software 

version and then reset the valve to the service position.

To access the spacer stack assembly remove the drive as-

sembly, drive cap assembly and piston.  The spacer stack 

assembly can be removed easily without tools by using thumb 

and forefinger.  Inspect the black o-rings and clear lip seals for 

wear or damage.  Replace the entire stack if necessary.  Do 

not disassemble the stack.

The spacer stack assembly may be chemically cleaned (dilute 

sodium bisulfite or vinegar) or wiped with a soft cloth.

The spacer stack assembly can be pushed in to the control 

valve body bore by hand.  Since the spacer stack assembly 

can be compressed it is easier to use a blunt object (5/8" to 

1-1/8" in diameter) to push the center of the assembly into the 

control valve body.  The assembly is properly seated when at 

least four threads are exposed (approximately 5/8".  Do not 

force the spacer stack assembly in.  The control valve body 

bore interior can be lubricated with silicone to allow for easy 

insertion of the entire stack.  Do not use silicone or any other 

type of lubricant on the clear lip seals or the piston.

Reattach the drive cap assembly and the piston(s) and the 

drive assembly.

After completing any valve maintenance, press and hold 

NEXT and REGEN buttons for 3 seconds or unplug power 

source jack (black wire) and plug back in.  This resets the 

electronics and establishes the service piston position.  The 

display should flash all wording, then flash the software ver-

sion and then reset the valve to the service position.

Unscrew the injector cap and lift off.   Loosen cap with special 

plastic wrench or pliers if necessary.  Attached to the injector 

cap is a screen.  Remove the screen and clean if fouled.

Reattach the drive cap assembly and the piston(s) and the 

drive assembly.

After completing any valve maintenance, press and hold 

NEXT and REGEN buttons for 3 seconds or unplug power 

source jack (black wire) and plug back in.  This resets the 

electronics and establishes the service piston position.  The 

display should flash all wording, then flash the software ver-

sion and then reset the valve to the service position.

Unscrew the injector cap and lift off.   Loosen cap with special 

plastic wrench or pliers if necessary.  Attached to the injector 

cap is a screen.  Remove the screen and clean if fouled.

The plug and/or injector can be pried out with a small screw-

driver.  The plug can be wiped clean.  If the plug leaks replace 

the entire plug.  The injector consists of a throat and a nozzle.  

Chemically clean the injector with vinegar or sodium bisul-

fite.  The holes can be blown out with air.  Both pieces have 

smaller diameter holes that control the flow rates of water to 

insure that the proper concentration of regenerant is used.  

Sharp objects, which can score the plastic, should not be 

used to clean the injector.  Scoring the injector or increasing 

the diameter of the hole could change the operating param-

eters of the injector.

Two holes are labeled DN and UP.  Check for compliance.   

See Table Below.

Push the plug(s)  and/or injectors firmly in place, replace the screen and hand tighten the injector cap.
