Please read all instructions, identify all components and read all warnings prior to beginning the installation of this product.
This product is intended to prevent catastrophic water damage in the event of a water heater leak. 

Please Note: 

During an emergency operating condition, the temperature and pressure relief valve installed on your water heater can 

discharge an excessive amount of water. It is designed to protect your home or business from the potential danger of explosion. Upon 

detection of this discharged water, the FloodSafe

®

 Water Detector Shutoff shuts off both the supply of water and the source of power 

(gas, oil or electricity) to the water heater, preventing a very dangerous situation.
The FloodSafe

®

 Water Detector Shutoff also contains an audible & visual alarm and contacts for monitored alarm systems. It is a reset-

table device and can be tested at any time to ensure proper operation.

Parts Included

Important Note: 

Thermostat wiring is required and must be supplied by the installer.

Planning Your Installation:

The Water Detector Shutoff should be installed within 6 to 12 inches of the water heater on the cold water inlet supply pipe.

The Control Unit, which houses the circuitry for the operation of the valve, contains interlocking connectors for the Water Detector Pad, 

the Power Supply and remote alarm and the Power Cutout Module. The cables provided should not be cut or extended; therefore, 

remote installation is not recommended.
The Water Detector Pad supplied with the Water Detector Shutoff should be located as close to the water heater as possible. It is not 

necessary to remove the cover of the Control Unit to install the interconnecting cables.

 Dirt flooring –

 A metal or plastic drain pan must be installed under the water heater. Position the Water Detector Pad inside the 

drain pan.
