IntelliFlow ®
Series A2C-M1
Automatic Washing Machine
Water Shutoff Valve with Leak Sensor
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
IntelliFlow
® ’s 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 or unattended.
Features
• 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 sen-
sor, 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.
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 stan-
dard three-prong 120 VAC washing machine power cable. The
valve shall actuate both the hot and cold water valves simultane-
ously 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 120 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 maxi-
mum pressure rating of 150psi (10.3 bar) and a maximum tempera-
ture rating of 180°F (82°C). The valve shall be UL listed for appli-
ance 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

How It Works
The 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 comple-
tion 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.
