IntelliFlow™ Automatic Washing Machine Shutoff Valves
Protect your home or business against water damage.
A burst washing machine hose can discharge 500 gallons of water in one hour and cause a flood of problems.
The Intelliflow's™ automatic operation protects against catastrophic water damage, should a water inlethose burst while the machine is not in use and unattended.
Protect your home or business with the IntelliFlow™ automatic washing machine shutoff valve and enjoy peace of mind.
How It Works
The Watts IntelliFlow™ Automatic Washing Machine Shutoff Valve uses a state-of-the-art electronic control device that senses the washing machine current flow. When the washing machine is turned on, the controls detect the current flow to the washer, opening both hot and cold water inlet valves to allow water to flow to the washing machine. When the washing machine completes the full cycle the device senses the lack of current and closes the water inlet valves. These valves remain closed until the machine is used again. The IntelliFlows™ automatic operation and floor mounted leak sensor protect against catastrophic water damage should a washing machine inlet hose burst while the machine is in use.
The contractor shall install an electrically actuated washing machine shutoff valve on the hot and cold water supply as indicated on the drawings. The electrically actuated washing machine valve shall be normally closed. The electrically actuated washing machine valve shall contain an integral electrical outlet capable of receiving a standard three-prong 115 VAC washing machine power cable. The valve shall actuate both the hot and cold water valves simultaneously upon detection of current flow at the integral electrical outlet which shall remain actuated until the detection of the interruption of current flow at the integral electrical outlet.
The valve shall be equipped with a 5 foot 14 AWG power cable. The valve shall be rated for 115 VAC, 60 Hz with a maximum standby current draw of less than one (1) ampere and a maximum appliance current draw of 15 amperes. The valve shall have a maximum pressure rating of 150psi (10 bar) and a maximum temperature rating of 180°F (82°C). The valve shall be UL listed for appliance controls. The electrically operated washing machine shutoff valve shall be equipped with a leak sensor. Upon detection of water at the leak sensor, current flow to both the hot and cold water valves shall be immediately interrupted. The valve shall be a Watts Intelliflow™ Model A2C-M1 surface mount unit or Model A2C-WB-M1 wall box unit.
Leak Sensor (A2C-LS)
Used in conjunction with the A2C-M1 or A2C-WB-M1, the leak sensor provides the maximum level of protection. Should water be detected at the leak sensor at any time, the water flow to the washing machine hoses will be cut off immediately. This protects against catastrophic water damage regardless of the operating cycle of the washing machine.
The Watts A2-IntelliTimer is used in conjunction with the Watts IntelliFlow™ Automatic Washing Machine Shutoff Valve. It is a remote timer which allows the IntelliFlow™ to be used in applications where the washing machine or a combination washer/dryer is 220 VAC powered. (The IntelliFlow™ is not compatible with 220 VAC powered appliances). The timer initiates a two-hour cycle when the button is depressed. The A2-IntelliTimer low voltage power supply is plugged into the IntelliFlow™ power outlet. The remote solid-state timer is installed in a location that is convenient to the user and connected to the low voltage power supply.
Activation of the push button on the timer causes current flow, which is detected by the IntelliFlow™. The IntelliFlow™ then actuates the solenoid valves, allowing water to flow to the washing machine. This also begins a timing sequence of two hours, which, upon its completion, deenergizes the IntelliFlow™, shutting off the flow of water to the washing machine. The timing sequence can be interrupted by activating the push button a second time. A Green LED is illuminated whenever the A2-IntelliTimer is energized.
- Easy installation
- Silent reliable operation
- Replaceable internal strainer screen
- The new Intelliflow™ Models A2C-M1 and A2C-WB-M1 also include a leak sensor. The water sensor is placed on the floor behind the washing machine.
- Upon detection of water at the sensor, the IntelliFlow™ automatically shuts off the water supply to the washing machine.
- This provides an additional level of security, should a hose burst while the washing machine is in operation.
