Operating Instructions

The Series A2C-SC IntelliFlow® Washing Machine Smart Water Shutoff senses your washing machine’s current flow and shuts off the water supply if an inlet hose bursts. It can also connect to your local WiFi network to send you real-time text and email alerts in the event of a leak.
The IntelliFlow is equipped with a state-of-the-art electric current sensing device. When a wash cycle is started, the IntelliFlow senses the electric current flowing to the washing machine and opens the supply of water to the washing machine. Once the full wash cycle is complete, the device senses the low current and closes the water inlet valves, which remain closed until the machine is used again.
The floor-mounted leak sensor provides additional protection from water damage while the washing machine is in use. When water is detected at the sensor, water flow to the washing machine hose is immediately shut off.
By installing an IntelliFlow, you’re helping to protect your home from potential major water damage from a burst or leaking washing machine inlet hose.

½” solder connectors for exposed piping Standardly furnished with ½” solder copper adapters. Either connection may be used for the hot or cold water supply.

Includes wall mount box. Wall mount box has water inlet connection holes spaced 2 ⅜” center to center. Furnished with ½” solder connectors. Either connection may be used for the hot or cold water supply.

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 Series A2C-SC / A2C-SC-WB. 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 washing machine hoses in order to prevent 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. Ensure 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 the front panel (Figure 2).

Note: Some washing machine models include circuitry that causes a slight current draw at all times. These models when connected to the IntelliFlow can cause the water supply to be energized continuously (Yellow LED: ON). The IntelliFlow can be reset by unplugging and reinstalling the leak sensor.

Accessories: Watts A2-IntelliTimer

The Watts A2-IntelliTimer is an optional accessory used in conjunction with the Watts IntelliFlow Washing Machine Smart Water Shutoff. It is a remote timer which allows the IntelliFlow to be used in applications where the washing machine or a combination washer/dryer is 240VAC powered. (The IntelliFlow 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 the current to 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.

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 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 an injury can occur.
The IntelliFlow does not cause or change the electrical differential that exists.
