SPACER STACK ASSEMBLY:
To access the spacer stack assembly remove the drive assembly, drive cap assembly and piston. The spacer stack as
-
sembly can be removed easily without tools by using your thumb and forefinger. Inspect the black o-rings and red or clear
lip seals for wear or damage. Replace the entire stack if necessary. The spacer stack assembly has been 100% tested at
the factory to insure proper orientation of one way seals.
DO NOT
disassemble spacer stack.
The spacer stack assembly may be chemically cleaned (dilute sodium bisulfite or vinegar) or wipe with a soft cloth.
The spacer stack assembly can be pushed into the control valve body bore by hand. Since the spacer stack assembly can
be compressed it is easier to use a blunt object (⅝” to 1⅛” 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 ⅝”)
DO NOT
force
the spacer stack assembly in. The control valve body bore interior can be lubricated with silicone to allow for easy inser
-
tion of the entire stack. Do not use silicone or any other type of lubricant on the red or clear lip seals or the piston.
Reattach the drive cap assembly and piston(s) and the drive assembly.
After completing any valve maintenance, press and hold
SET HOUR
and ▼ buttons for 5 seconds or unplug power
source jack (black wire) from the circuit board and plug back in. This resets the electronics and establishes the filtering
position. Reset the time of day.
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 at
-
tached 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.
METER PLUG:
This control valve does not come equipped with a meter, instead a plug is installed. The plug should not need to be ser
-
viced.
To remove the meter plug 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 meter plug is visible. Twist a flat blade screwdriver in the slot between the
control valve body and the meter plug. When the meter plug is part way out it is easy to remove the meter plug from the
housing.
DO NOT
use a wire brush to clean. Wipe with a clean cloth or chemically clean in dilute sodium bisulfite or vinegar.
DO NOT
use Vaseline, oils, or other unacceptable lubricants on o-rings. A silicone lubricant may be used on the black
o-ring.
Reinsert the meter plug into the side slot. Hand tighten the nut. Do not use a pipe wrench to tighten nut.
