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

NFPA 70, Section 210.11 Branch Circuits Required, at

least one 20-ampere branch circuit shall be provided to

supply the laundry receptacle outlets(s) required by

Section 210.52(F). This circuit shall have no other outlets.

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.
