Water Meter or Meter Plug
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 in 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 through the drive back plate and side of the drive assembly. Reattach the drive assembly and the water meter and power plugs.
If no water meter 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 be- tween 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 bear- ings are prelubricated. Do not use Vaseline, oils, or other unacceptable lubricants on the
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.
Bypass Valve
The working parts of the bypass valve are the rotor as- semblies that are contained under the bypass valve caps. Before working on the rotors, make sure the system is de- pressurized. Turn the red arrow shaped handles towards the center of the bypass valve and back 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 ro- tor, 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
When installing the red arrow handles be sure that:
1.The handle pointers are lined up with the control valve body arrows, and the rotor seal
2.Arrows point toward each other in the bypass position.
Since the handles can by pulled off, they could be ac- cidently reinstalled 180º 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 soft- ware version and reset the valve to the service position.
