Maintenance Manual
Injector Cap, 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 re
-
place 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 param
-
eters of the injector.
Two holes are labeled DN and UP. Check for compliance with one of the following:
a. for down flow systems, the appropriate size injector is located in the “DN” 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;
b. for up flow systems, the appropriate size injector is located in the “UP” hole, a plug is in the “DN” hole and that the
piston is a combination of the up flow main piston and the regenerant piston; or
c. 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 Control Assembly or Refill Port Plug
To clean or replace the refill flow control, pull out the elbow-locking clip and then pull straight up on 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 con
-
trol 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 use a
wire brush. If necessary, replace the flow control, o-ring on the flow control retainer, or the o-ring on the elbow.
Reseat the flow control so the rounded end is visible in the flow control.
Reseat the white flow control retainer by pushing the retainer into the
elbow until the o-ring 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 o-ring on the elbow or the white
retainer.
