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 soft ware version and then
reset the valve to the service position.
Injector Can. Screen Injector Plug and Injector
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 screwdriver. 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 bisulfite. 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.
Two holes are labeled DN and UP. Check for compliance with one of the following:
for down flow systems, the appropriate size injector in located in the “DM’ hole, a plug is in the “UP”
hole and that the piston is a combination of the down flow main piston and the regenerant piston.
for up flow systems, the appropriate size injector is located in the “UP” hole, a plug is in the “Whole and
that the piston is a combination of the up flow main piston and the regenerant piston; or
for backwash only systems, a plug is in the “DN” hole and in the “UP” hole, and that the piston only has
a down flow main piston (the regenerant piston must be removed) and a plug is in the refill flow control
position.
Push the plug(s) and/or injectors firmly in place, replace the screen and hand tighten the injector cap.
Refill Flow Contrpl Assembly or-Refill Port Plug
To clean or replace the refill flow control, pull out the elbow-locking clip and then pull straight upon the
elbow. Replace the elbow locking clip in the slot so that it is not misplaced. Twist to remove the white
flow control retainer. The flow control can be removed by prying upward through the side slots of the
retainer with a small blade flat screwdriver.
Chemically clean the flow control or the white flow control retainer using dilute sodium bisulfite or
vinegar. Do not me a wire brush. If necessary, replace the flow control, wring on the flow control
retainer, or the 0-ring on the elbow.
Reseat the flow control so the rounded end is visible in the flow control. Reseal the white flow control
retainer by pushing the retainer into the elbow until the wring seats. Remove locking clip, push down on
elbow to reseat and insert locking clip.
Do not use Vaseline, oils, or other unacceptable lubricants on o-rings. A silicon lubricant may be used on
the n-ring on the elbow or the white retainer.
