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 rotor, make sure the system is depressurized. Turn the red arrow shaped handles toward 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 tighten 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
pointers 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 accidentally reinstalled 180° from their correct orientation. To install the
red 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

softening. Reset the time of day.
