IntelliFlow

Automatic Washing Ma chine

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 low 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 sen-

sor protect against catastrophic water damage should a washing

machine inlet hose burst while the machine is in use or unattended.

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.

Specifications

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 simultaneously

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 maximum pres-

sure rating of 150psi (10.3 bar) and a maximum temperature rating

of 180°F (82°C). The valve shall be UL listed for appliance 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 Intelliflow

WARNING

† It is suggested that the electrical power source be ground fault

protected. In accordance with National Electric Code, 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 elec tric cur-

rent sensing device. When the washing machine starts a wash cycle,

the IntelliFlow

senses the electric current flowing to the washing

machine and opens the supply of water to washing machine. Upon

completion of the full wash cycle, the washing machine shuts off and

returns to original current level. The IntelliFlow

senses the low cur-

rent and closes both the hot and cold water supplies.

Leak Sensor Used in conjunction with the A2C-M1 or A2C-WB-M1, the leak sensor provides the maximum level of protection. Should water be detected at the leak sensor at any time, the water flow to the washing machine hoses will be cut off immediately. This protects against catastrophic water damage regardless of the operating cycle of the washing machine. Optional Accessories Leak Sensor A2-IntelliTimer: A remote timer which allows the IntelliFlow® to be used with 240 VAC powered appliances.
