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.

Description:

The Watts Model A2-LS Leak Sensor plugs into the receptacle on the front panel of the Watts IntelliFlow A2-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 washing machine hoses preventing catastrophic water damage.

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 receptacle on front panel (Figure 2).

Some washing machine models include circuitry that causes a slight cur rent draw at all times. These models when connected to the IntelliFlow cause the water supply to be energized continuously (Yellow LED: ON). The IntelliFlow

can be reset by unplugging and reinstalling the leak sensor. If this does not resolve this issue, the use of the A2 IntelliTimer is required with the system in use.

4. Unit feels warm: This condition is normal. Internal operating temperatures may cause unit to feel warm to the touch.

5. Unit cycles ON/OFF: Installation in a horizontal position can cause abnormal overheating of the unit which causes this cycling condition. Unit must be installed in an upright posi tion as shown on pages 2 and 3.

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

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.

BLINKING: Unit Timed Out – This lamp blinks whenever the internal timing circuit has timed out and has shut off the water supply to the washing machine hoses. Turning the washing machine Off then On will reset the timing circuit.

FAINT BLINK: (3-5 seconds) – This condition indicates the leak sensor is unplugged. To provide the maximum level of protection, it is recommended that the leak sensor be installed at all times.

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.
