Service Instructions
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 and the water meter and power
plugs.
If a water meter wire is not visible, then a plug is installed not
a water meter.
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 bear-
ings 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 unac-
ceptable lubricants on the o-ring. A silicon 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 pipe wrench
to tighten nut.

The working parts of the bypass valve are the rotor assem-
blies that are contained under the bypass valve caps. Before
working on the rotors, make sure the system is depressurized.
Turn the red arrow shaped handles towards the center of the
bypass valve and back to the arrow direction several times to
ensure rotor is turning freely.
The nuts and caps are designed to be unscrewed or tightened
by hand. If necessary a pliers can be used to unscrew the nut
or cap. Do not use a pipe wrench to tighten or loosen nuts or
caps. Do not place screwdriver in slots on caps and/or tap
with a hammer.
To access the rotor, unscrew the cap and lift the cap, rotor and
handle out as one unit. Twisting the unit as you pull it out will
help to remove it more easily. There are three o-rings: one
under the rotor cap, one on the rotor stem and the rotor seal.
Replace worn o-rings. Clean rotor. Reinstall rotor.
When reinstalling the red arrow handles be sure that:
1. O-rings on both rotors face to the right when being viewed
from the front of the control valve when the handle point-
ers are lined up with the control valve body arrows; or
2. Arrows point toward each other in the bypass position.
Since the handles can be pulled off, they could be accidental-
ly reinstalled 180° from their correct orientation. To install
the red arrow handles correctly, keep the handles pointed in
the same direction as the arrows engraved on the control
valve body while tightening the bypass valve caps.
After completing any valve maintenance, press and hold
NEXT and REGEN buttons for 3 seconds or unplug power
source jack (black wire) and plug back in. This resets the
electronics and establishes the service piston position. The
display should flash all wording, then flash the software ver-
sion (e.g. 154) and then reset the valve to the service position.
