Waterguard+ installed on cold and hot water (kitchen)

System for detecting water leakage and automatic kitchen water supply shut-off.

Waterguard+ is well suited for detecting water leaks in kitchens with automatic shut-off of the kitchen's supply of both cold and hot water.

A modern kitchen usually has access to both hot and cold water. It is necessary to turn off both water sources to prevent leaks. Many water connections (sink, dishwasher, refrigerator, coffee maker, etc.) make the kitchen particularly vulnerable to leaks and water spills. Without a drain and membrane, a leak can lead to damage to floors, walls and kitchen furniture. The installation described in this article ensures that water leaks are detected and prevents major damage.

This installation detects and prevents bigger leakages and it satisfies the Norwegian building regulation for water installations (TEK17 §15-5 - Requirement for automatic leakage detection and water shut-off system in wet rooms). PS! This regulation only applies in Norway.

Water is detected by Water Sensor Tape and the Linkbox+ will automatically close the valve (1/2" or 3/4" mounted on the kitchen water intake) and the water supply.  The system alerts the user immediately with sound, light and push-notification in the Abralife app.

The system also allows the user to control the valve manually (physically or via app) if needed (e.g. longer absence from the home or cabin).

The Waterguard valves perform an automatically exercise if not used in 7 days. This ensures a healthy and operational valve.

Description

Icon	Product	Description
	Linkbox+ (Central Unit)	The Linkbox+ (B) is installed in a suitable place in or behind the kitchen furniture using the included bracket. The inluced Linkbox+ power adapter is inserted and the Cat6 cable is connected between the valve actuator and the Linkbox+
	Ball Valve (1/2" or 3/4")	The valve (C) is installed by a authorized plumber on the kitchen cold-water intake.
	Water Sensor Tape	The self-adhesive Water Sensor Tape is connected to the Linkbox+ (3,5 mm Jack) and brought down under the furniture and fastened to the floor where any water is predicted to end up in case of a leakage. For the tape to be properly fastened, ensure the surface is clean before application.

Additional information

Before the Linkbox+ (B) is mounted, ensure correct placement based on:

• Distance to the valve (the Cat-cable included is 2 meters long. If not possible to install within 2 meters, the Cat-cable must be replaced with a longer (optional product)
• Distance to power outlet (The power adapter cable is approx. 1,5 meter)
• The coverage area of the Water Sensor Tape (The tape is 3 meter long and should cover the area where the risk of leakage is big)

PS! If the include Water Sensor Tape does not cover the full area (e.g. the kitchen has an kitchen island or the distance between the water-connected products is large), you can add wireless WaterSensor+ or extend the Sensor Tape. See chapter Additional Products and Options below for more information.

Additional products and options

• If the included Water Sensor Tape is too short, the Sensor Tape Extension Connector or Sensor Tape Splitter can be used for connection one additional Tape (2 x 3 meter)
• Additional wireless sensors (WaterSensor+) can be added to the system if the Sensor Tape is not sufficient or the user want to measure temperature or humidity in other areas of the home.
• The system can be extended with one additional valve (e.g. kitchen warm water intake) by using a Valve Cable Splitter.
• Linkbox+ can control other smart products and solutions for the home. For more information, visit www.abralife.com
