INJECTOR CAP, SCREEN, INJECTOR PLUG AND INJECTOR:
Unscrew the injector cap and lift off. Loosen cap with optional maintenance wrench or pliers if necessary. A screen is
attached to the injector cap. 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 consist of a throat and a nozzle. Chemically clean the injector with vinegar or dilute sodium bisulfite.
The holes can be blown out with air. Both pieces have small diameter holes that control the flow rates of the water to insure
that the proper concentration of the 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. For down flow systems, the appropriate injector is located in the “DN” hole, a plug is in
the “UP” hole. Push the plug and injector 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 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
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 silicone lubricant may be used on the o-ring on
the elbow or white retainer.
WATER METER OR METER PLUG:
The water meter assembly is connected to the PC board by a wire. If the entire water meter assembly is to be replaced,
remove the control valve cover and remove the power source and water meter plugs from the PC board. Unlatch the drive
assembly and lean it forward. Unthread the water meter wire from the side of the drive assembly and through the drive plate.
To reinstall, rethread the water meter wire through the drive back plate and the side if the drive assembly. Reattach the drive
assembly and the water meter and power plugs.
The water meter wire does not need to be removed from the PC board if the water meter is only being inspected and
cleaned. To remove the water meter assembly, unscrew the meter cap on the left side of the control valve. Pliers may be
used to unscrew the nut if necessary.
With the nut removed, a slot at the top of the water meter is visible. Twist a flat blade screwdriver in the slot between the
control valve body and the meter. When the meter is part way out it is easy to remove the water meter from the housing.
Once the water meter is removed from the control valve body, use your fingers to gently pull forward on the turbine to
remove it from the shaft.
Do not use a wire brush to clean. Wipe with a clean cloth or chemically clean in dilute sodium bisulfite or vinegar. The turbine
can be immersed in the chemical. Do not immerse electronics. If the turbine is scored or damaged or the bearings on the
turbine are worn replace the turbine.
Do not lubricate the turbine shaft. The turbine shaft bearings are pre-lubricated. Do not use Vaseline, oils or other unacceptable
lubricants on the o-ring. A silicone may be used on the black o-ring.
Snap the turbine on the shaft and reinsert the water meter into the side slot. Hand tighten the nut. Do not use a pipe wrench
to tighten nut.
