Reattach the main piston to the drive cap assembly. Reattach the regenerant piston to the main piston. Do not
lubricate the piston rod, main piston or regenerant piston. Lubricant 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 the special wrenchor 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 moulded 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 SET HOUR and DOWN

buttons for 3 seconds or unplug power source jack (black wire)
at the circuit board and plug back in. This resets the electronics and establishes the service piston position.
Spacer Stack Assembly
To access the spacer stack assembly remove the drive assembly, 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 with 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 (15.9mm (5/8”) to 28.6 mm (1-1/8”) in diameter)
to push the centre of the assembly into the control valve body. The assembly is properly seated when at least
four threads are exposed (approximately 15.89 mm (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 piston(s) and the drive assembly.

Injector Cap, Screen, Injector Plug and Injector
Unscrew the injector cap and lift off. Loosen cap with special wrench or pliers if necessary. Attached to the
injector cap is a screen. Remove the screen and clean if fouled.
The injector can be pried out with a small screwdriver. The injector consists of a throat and a nozzle.
Chemically clean the injector with vinegar. The holes can be blown out with air. Both pieces have small
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 parameters of the injector. Push the injector
firmly in place, replace the screen and hand tighten the injector cap.
Two holes are label “DN” and “UP”. Check for compliance. See Compliance table
