Piston Assembly/Seal And Spacer Cartridge Replacement - Pentair FLECK 2815 Service Manual

PISTON ASSEMBLY/SEAL AND SPACER
CARTRIDGE REPLACEMENT
1. Turn off water supply to valve.
2. Open/remove powerhead assembly cover.
3. Cycle valve to backwash position. Wait until there is no
water flow at the drain to ensure the unit is depressurized
then cycle valve to service position. If you are unable to
advance the valve to the backwash position, open a water
line to depressurize the system.
4. Remove electrical plug from outlet.
5. If present, detach the meter cable from the meter cap.
6. Detach the spring clip securing the timer to the powerhead
assembly backplate and swing timer out of the way.
7. Remove the connecting rod spring pin from piston rod.
8. Remove the two bolts (10mm nut driver) securing the
motor assembly to the end plug assembly.
9. Swing motor out of the way (depending upon the wire
harness length tension you may need to disconnect/remove
the wiring harness)
10. Remove the three bolts (10mm nut driver) from the end
plug assembly.
11. Install the connecting rod spring pin back into the piston
rod.
12. Using a needle-nosed pliers and the connecting rod spring
pin as an anchor point, remove the endplug and piston
assembly. Alternatively, you may pry the end plug assembly
loose using a flat nosed screwdriver against the end plug
assembly inlayed grooves.
13. Carefully remove the seal and spacer cage assembly
14. Lubricate the inner diameter and outer diameter of the
new seal and spacer cage.
Only use 100% silicone lubricant that is approved for use with
potable water.
15. Install the new seal and spacer cage (either end can be
inserted; orientation is interchangeable)
16. Install the piston assembly and end plug (by lining up to the
three bolt holes and noting the orientation of the two motor
assembly bolt holes). The end plug will not be flush with
the backplate until all three bolts are tightened.
17. Install the three bolts by hand only to hold the end plug
assembly in place so you may adjust the piston rod in
alignment with the motor assembly drive link. Swing motor
asssembly into place and adjust piston rod as needed.
Keep in mind the piston rod, motor assembly drive link,
and clip pin all need to align.
18. Swing motor assembly out of the way and begin tightening
the three end plug bolts. Tighten the three bolts evenly in a
criss-cross sequence.
19. Swing the motor back into place, align the motor assembly
drive link with the slotted piston rod and secure with the
connecting rod spring clip.
20. Secure the motor assembly to the backplate using the two
motor assembly bolts.

with the spring clip. Set time of day.
22. If present, reattach meter cable to meter cap.
23. Plug electrical plug into power outlet.
24. Restore water supply to valve (purging air). Cycle valve
to backwash to purge the air from the system. Refer
to startup instructions for more information about
pressurizing the system.
25. Check for leaks.
26. Close powerhead assembly cover.

4. Remove electrical plug from outlet.
5. Remove brine line
6. If present, detach the meter cable from the meter cap.
7. Detach the spring clip securing the timer to the powerhead
assembly backplate and swing timer out of the way.
8. Remove the connecting rod spring pin from piston rod.
9. Remove the two bolts (10mm nut driver) securing the
motor assembly to the end plug assembly.
10. Swing motor out of the way (depending upon the wire
harness length tension you may need to disconnect/remove
the wiring harness)
11. Remove brine nut using crescent wrench
12. On valve, remove the three bolts securing the injector
assembly using an 8mm socket wrench
13. Slide injector assembly and brine assembly out of
backplate
14. Remove the H-clip connecting the injector assembly to the
