Installing the Watts Model A2-LS Leak Sensor
Description
The Watts Model A2-LS Leak Sensor plugs into the receptacle on the front panel of the
Watts IntelliFlow Series A2C-SC / A2C-SC-WB. The base of the sensor is placed on the
floor close to the washing machine. Upon detection of water at the sensor, the IntelliFlow
immediately shuts off the water supply to the washing machine hoses in order to prevent
catastrophic water damage.
Installation
1. Insert the leak sensor contacts into the two holes on the top of the sensor base until the
plug comes to a stop (Figure 2).
2. Place the sensor base on the floor behind the washing machine as close to the fill hoses as
possible. Ensure that the sensor base is lying flat with all feet in contact with the floor sur-
face.
3. Insert the leak sensor plug (Figure 1) into the leak sensor receptacle on front panel
(Figure 2).
Note: Some washing machine models include circuitry that causes a slight current draw at all
times. These models when connected to the IntelliFlow can cause the water supply to
be energized continuously (Yellow LED: ON). The IntelliFlow can be reset by unplugging
and reinstalling the leak sensor.
