Spacer Stack Assembly
Disassembly and Inspection:
To access the spacer stack assembly remove the drive assembly, drive cap assembly
and piston. The spacer stack assembly can then be pulled straight out. Inspect the black o-rings and inner seals for wear
or damage; replace the entire stack if necessary. Do not disassemble the stack. The spacer stack assembly may be
chemically cleaned (in dilute sodium bisulfite or vinegar) or wiped with a soft cloth.
Reassembly:
The spacer stack assembly can be pushed into the control valve body bore by hand. 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 insertion of the entire stack.
Reattach the drive cap assembly and piston(s) and the drive assembly.
After completing any valve maintenance, press and hold NEXT and REGEN buttons for 3 seconds or unplug power
source jack (4 pin, black cable) and plug back in. This resets the electronics and establishes the service piston position.
The display should flash all wording, then flash the software version and then reset the valve to the service position.
Injector Cap, Screen, and Injector Plug
Disassembly and Inspection:
The injector can be accessed at the back of the valve by removing the threaded injector
cap. The cap is removed by using the V3193-02 service wrench (figure 1). Once the cap is removed, use the open end
of the V3193-01 service wrench at an angle to pry out the injector. The injector plug should not need to be cleaned, just
verify that it has both o-rings on the plug and that it is fully seated.
Reassembly:
Press the injector plug into its bore hole and press until seated all the way down. Replace the injector cap.
Refill Port Plug
Disassembly and Inspection
: Refill port plugs should not need to be serviced. O-rings may be replaced if necessary.
Pull out the locking clip and then pull the fitting straight out. Remove the flow control retainer. If necessary, replace the o-
rings. A silicone lubricant may be used, but do not use Vaseline, oils, or other unacceptable lubricants on o-rings.
Reassembly:
Insert the flow control into its seat, confirming correct flow control orientation. Reseat the flow control
retainer and reassemble the fitting (see diagram in the exploded view section). 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 the retainer, but not on
the flow control or its seat. Refill port plugs should not need to be serviced. O-rings may be replaced if necessary.
Drain Line Flow Control
Disassembly and Inspection:
Depending on the flow control installed on the unit, remove the red plastic retaining clip
(plastic flow control) or the (4) screws (stainless steel flow control) to expose the flow control and retainer. The flow
controls can be removed by flexing the washer with a small screwdriver being careful not to mar the plastic seat. The flow
control and retainer may be chemically cleaned using dilute sodium bisulfite or vinegar, do not clean with abrasive
methods.
Reassembly:
Insert the flow washers back into their respective bores, confirming correct flow control orientation (see
diagram in the exploded view section). Place back into the housing and reassemble the housing /fitting. Do not use
Vasoline, oils or other unacceptable lubricants on o-rings. A silicone lubricant may be used on the o-ring of the elbow or
the retainer, but not on the flow control or its seat.
Meter Assembly Service Instructions
Service or replace turbine by:
Turn the bypass for the system on and relieve the pressure on the system before removing the meter.
Press downward on the remote meter assembly to relieve tension on the retaining clip. Remove the clip and take the
meter assembly out of the housing.
Remove the bend from the two exposed tips of the retaining clip and remove clip.
Service or replace the turbine assembly and place it back on the turbine shaft.
Insert the turbine clip and re-bend the exposed ends of the clip. The turbine has a groove to line up with the turbine
clip.
Insert meter assembly back into the meter housing.
Reinstall the meter retaining clip.
Open the bypass for the system slowly to bring back into service and check to be sure you have no water leaks.
