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 main piston and the regenerant piston;
b. for backwash only systems, a plug is in the “DN” hole and in the “UP” hole, and that only the main
piston exists (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 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 vin-
egar. Do not use a wire brush. If necessary, replace the flow control, flow control retainer o-ring, or the
elbow o-ring.
Reseat the flow control so the rounded end with lettering is visible in the flow control retainer. Reseat
the white flow control retainer by inserting the retainer into the elbow until the o-ring seats. Remove
locking clip, insert elbow into valve body to reseat, and insert locking clip.
Do not use Vaseline or other petroleum based oils on o-rings. A silicone lubricant may be used on the
the elbow o-ring or the white retainer.
WATER METER OR METER PLUG
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.
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 back plate. To reinstall, rethread the water meter
wire through the drive back plate and the side of the drive assembly. Reattach the drive assembly,
water meter, and power plugs.
If there is no water meter wire visible, then a plug should be found in the meter location.
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 check
that the turbine spins freely. If it does not, use two fingers behind the blades to gently pull the turbine
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 prelubricated. Do not use Vaseline,
oils, or other lubricants on the o-ring. A silicone lubricant 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 wrench.
