Automatic Washing Machine Shutoff Valve
Model A2C-M1, A2C-WB-M1
NOTICE
This unit is not compatible with 240VAC powered washing
machines or combination washer/dryers that are 240VAC pow-
ered. A Watts A2-IntelliTimer (purchased separately) may be
used with the IntelliFlow
®
with washing machines or washer/dry-
ers that are 240VAC powered. (See page 5)
A2C-M1 IntelliFlow
®
Patent Number 6,003,536
Leak Sensor
IS-A2C-M1/A2C-WB-M1
*This valve requires a 120VAC, 60 Hz,
20 amp ground fault protected circuit.
*Ground Fault Interrupter – A GFI circuit is not
required for proper operation of the IntelliFlow
®
, but is
strongly recommended as a safety device.
Operating Instructions
The Watts IntelliFlow
®
Automatic Washing Machine Shutoff Valve is equipped with a
state-of-the-art electric current sensing device. When the washing machine is turned
on, the device senses current flow to the washing machine. This causes it to actuate
its solenoid water valves, allowing water to flow to the washing machine. When the
washing machine shuts off upon completion of the full wash cycle, the device senses
the lack of current and closes the water valves. The IntelliFlow
®
remains closed until
the next time you turn the washer on.
The leak sensor provides additional protection from water damage while the washing
machine is in operation. Water detected at the sensor results in immediate shut off of
water flow to the washing machine hose.
By installing an IntelliFlow
®
, you are protecting your home from potential major water dam-
age from a burst or leaking washing machine inlet hose.
