Automatic Washing Machine Shutoff Valve Model A2C-M1, A2C-WB-M1

Important! Read instructions completely before proceeding.

Note: This unit is not compatible with 240VAC powered wash-

ing machines or combination washer/dryers that are 240VAC powered. A Watts A2-IntelliTimer (purchased separately) may be used with the IntelliFlow ers that are 240VAC powered. (See page 5)

*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 A2C-M1 IntelliFlow

WARNING:

Power MUST be off during installation or

servicing of the valve!

IMPORTANT: Do not plug valve into supply circuit

until completion of assembly.

For Vertical Installation Only!

1. Shut off electrical power supply.

2. Shut off both hot and cold water supply lines.

3. If retrofitting to an existing installation, disconnect the washing machine hoses from the existing shutoff valve(s).

4. Loosen the two (2) adapter nuts and remove both adapters from IntelliFlow

5. Place adapter nuts over piping prior to soldering adapters.

6. Solder adapters onto piping. Note: Piping must be 23⁄8" on center (Figure 3).

7. Place O-rings on adapter grooves (Figure 3A).

Align and slip the valve body over adapters. Tighten adapter nuts.

Caution: Do not over-tighten nuts. Caution: To avoid cross threading, check thread alignment.

9. Connect the washing machine hoses to the IntelliFlow and cold water outlets.

10. Plug the washing machine into the IntelliFlow Note: Appliance current rating must not exceed 15 amps.

11. Plug the IntelliFlow receptacle (Figure 4). Note: The IntelliFlow®requires a 120VAC, 60Hz, 15 amp ground-fault protected receptacle.*

Installing the IntelliFlow®Wall Box Unit (A2C-WB-M1)

WARNING:

Power MUST be off during installation or

servicing of the valve!

IMPORTANT: Do not plug valve into supply circuit

until completion of assembly.

For Vertical Installation Only!

1. Shut off electrical power supply.

2. Shut off both hot and cold water supply lines.

3. Remove trim plate (Figs. No.5 & 6) and set aside until you’ve completed wall finishing (painting, wall papering, paneling, etc.).

4. Install the four mounting tabs provided in slots on the sides of the wall box enclosure (Fig. No. 7).

5. Position the A2C-WB-M1 between the wall studs as shown in Fig. No. 7. Check that it is level and fasten the mounting tabs to the studs.

6. Remove drain plug knock out. Install drain piping and water supply piping to the appropriate IntelliFlow Either IntelliFlow

connection may be used for the hot or

cold water supply. Caution: Excessive heat from soldering can damage plastic components. Use a heat sink to prevent damage.

7. Place O-rings on adapter grooves (Figure No. 3A).

Align and slip the valve body over adapters. Tighten adapter nuts.

Caution: Do not over tighten nuts. Caution: To avoid cross threading, check thread alignment.

9. Prior to installing wall materials, turn on water supply (both hot and cold) and test for leaks. Test drain piping for leaks.

10. Turn off water supply until you’ve completed installing wall materials. Note: Installation must comply with local codes and ordinances. Inspection and approval of installation by local authorities may be required prior to installation of wall material. Check with local plumbing authorities for requirements.

11. Once you’ve finished the wall, install trim plate, connect washing machine water supply hoses to the IntelliFlow valve and to the washing machine.

12. Plug washing machine into the IntelliFlow Note: Appliance current rating must not exceed 15 amps.
