Bypass Valve
The working parts of the bypass valve are the rotor assemblies 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 centre 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 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. The handle pointer are lined up with the control valve body arrows, and the rotor seal o-
ring and retainer on both rotors face to the right when being viewed from the front of the
control valve; or
2. Arrows point toward each other in the bypass position.
Since the handles can be pulled off, they could be accidentally 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) at the circuit board and plug back in. This resets the electronics
and establishes the service piston position. The display should flash all wording, then flash the
software version and then reset the valve to the service position.
