BYPASS VALVE OVERVIEW

Bypass Valve
The Bypass Valve can isolate the appliance should appliance malfunction or leak. It can also
permit the use of untreated water for watering plants, shrubs, or lawns.
The Bypass Valve is attached to the main control valve. To engage Bypass Valve, remove
the cabinet cover and locate the knob. Turn knob to the left until it hits the stop. The
appliance will be bypassed and all water to the home is raw, untreated water. To prevent
untreated water from entering the home, water should not be used inside the home when
the appliance is in Bypass Mode. Ensure that the appliance is returned to Service Mode
when the appliance is repaired or the use of untreated water is complete by turning the
black knob to the right until it hits the stop.
