Watts A2CWB-0004646 IntelliFlow Wall Box Washing Machine Water Shut-Off Valve

The Watts A2CWB-0004646 IntelliFlow Wall Box Washing Machine Water Shutoff Valve with Leak Sensor is used in residential applications to protect against catastrophic water damage from a burst inlet hose connected to a washing machine in use or unattended. The A2CWB-0004646 IntelliFlow senses when the washing machine is on or off, and then opens or closes the hot and cold inlet valves as needed to allow or prevent water from flowing to the washer. If the A2CWB-0004646 detects a leak, current flow to both the hot and cold water valves are immediately interrupted and closed. It consists of an electrical three-prong outlet to receive a washing machine power cable, wall box, leak sensor, a power cord, and a replaceable internal strainer screen.

Features:

• Easy installation
• Silent reliable operation
• Replaceable internal strainer screen
• Leak sensor
• Maximum Pressure: 150 psi (10.3 bar)

*NOTE: It is suggested that the electrical power source be ground fault protected. In accordance with National Electric Code, NFPA 70, Section 210.11 Branch Circuits Required, at least one 20-ampere branch circuit shall be provided to supply the laundry receptacle outlets(s) required by Section 210.52(F).

How It Works
A2CWB-0004646 IntelliFlow DrawingThe Watts IntelliFlow® is equipped with a state-of-the-art electric current sensing device. When the washing machine is turned on, the IntelliFlow® senses the current flowing to the washing machine and opens the supply of water to washing machine. Upon completion of the full wash cycle, the washing machine shuts off, cutting off the current. The IntelliFlow® senses this lack of current and closes both the hot and cold water supplies.
