Water Meter
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 disconnect 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.
THIS WATER METER SHOULD NOT BE USED AS THE PRIMARY
MONITORING DEVICE FOR CRITICAL OR HEALTH EFFECT APPLICATIONS.

If no water meter wire is 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, gently pull forward on the turbine to remove it from the shaft.
Do not use a wire brush to clean the turbine. 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 unacceptable lubricants on
the o-ring. A silicone lubricant may be used on the black o-ring.
Reinsert the water meter into the side slot. Hand tighten the nut. Do not use a pipe wrench to tighten nut.
