*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.
Surge Protection – Although a surge protector is not
required for proper operation of the IntelliFlow®, it is strongly
recommended, especially in areas where power surges or
lightning strikes frequently occur.
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.

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
WB-M1. 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 wash-
ing machine hoses preventing catastrophic water damage.
®
Series A2C-M1 or A2-
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. Insure that the sensor base
is lying flat with all feet in contact with the floor surface.
3. Insert the leak sensor plug (Figure 1) into the leak sensor
receptical on front panel (Figure 2).
IntelliFlow®Calibration Procedure
Some washing machine models include circuitry that causes a
slight current draw at all times. These models when connected
to the IntelliFlow
continuously (Yellow LED: on). Calibration allows the IntelliFlow
to “learn” the off or standby current draw of the washing
machine to prevent this condition.
Calibration: (Startup)
Calibration must be performed with the washing machine in the
off position.
1. Before plugging in the IntelliFlow
cal receptacle, ensure that the leak sensor plug (Figure 1) is
unplugged from the IntelliFlow
2. Plug the IntelliFlow
The green LED lamp should be on and stay on continuously.
The red LED lamp should light for a few seconds then start
to blink on and off, as an indication that the leak sensor is
not plugged in.
3. Be sure that the washing machine is
machine into the IntelliFlow
4. Plug the leak sensor plug into the leak sensor receptacle on
the front panel. This will calibrate the IntelliFlow
ing machine's off or standby position current draw. During the
calibration sequence, the red LED lamp will remain lit for
approximately 3-5 seconds. When calibration is complete the
red LED lamp will blink four (4) times and shut off.

Notes:
The IntelliFlow®is designed to maintain its calibration in the
event of a power failure. Should calibration ever be required, follow the procedure below.

Accessories: Watts A2-IntelliTimer
The Watts A2-IntelliTimer is an optional accessory used in conjunction with the Watts IntelliFlow
Shutoff Valve. It is a remote timer which allows the IntelliFlow
be used in applications where the washing machine or a combination washer/dryer is 240VAC powered. (The IntelliFlow
®
Automatic Washing Machine
®
®
is not
to
compatible with 240VAC 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 de-energizes 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.
Note: For calibration procedure see Page 4, “Calibration using
IntelliTimer Accessory”.

What is Surge Protection?
In many locations, changes in the AC voltage supply to the home by the
electrical utility company can occur. Both lower voltage (brownouts) and
high voltage (surges) can occur. Lightning strikes can also cause high
voltage spikes to occur.
All electronic equipment is designed to operate properly within a
voltage range. However, high voltage surges or spikes can damage sensitive circuitry within electronic equipment.
Surge protectors prevent voltage spikes from reaching
electronic equipment.
What is Ground Fault Protection?
In many locations, an electrical differential between an electrical ground
and a water pipe ground can exist. A person touching both grounds
could receive a shock that may cause injury or death. A ground fault
interrupter circuit (GFI) detects the differential and removes electrical
power before injury can occur.
The IntelliFlow®does not cause or change the electrical differential that exists.
