YOUR GUIDE TO THE GROHE SENSE GUARD INSTALLATION

For safety advices, please see the product manual included in the packaging (sensecheck.grohe.com/manual)

The GROHE SenseCheck is designed to help installers and end users with the installation of the GROHE Sense Guard. We recommend that the SenseCheck is done by an installer together with the inhabitant of the house/end user where the Guard is being installed.

CAN THE GROHE SENSE GUARD BE INSTALLED AT THE LOCATION?

PLEASE NOTE THAT THE GROHE SENSE GUARD HAS BEEN DEVELOPED FOR THE FOLLOWING SITUATIONS:

single family houses

only one person is able to decide to shut off the water supply, without negative impact on other inhabitants

BE AWARE THAT THE GROHE SENSE GUARD CANNOT BE INSTALLED:

on hot water pipes

outside the house

in rooms with frost risk

when flow pressure is below 0.05 Mpa/0.5 bar/7 psi

when flow pressure is higher than 1 Mpa/10 bar/145 psi (can be solved by pressure reducer)

in high pressure gravity pumped water systems

General remark: The micro-leakage test is limited to the cold water pipe. Smaller leakages on the hot water pipe may not be detected.

1. PLAN

1.1 Is there enough room?

(between water meter and where pipe splits to the heating system)

The GROHE Sense Guard needs to be installed between the water meter and the junction between hot and cold water. GROHE Sense Guard needs to be installed as close to the water meter as possible for maximum water security.

Please consider the dimensions below and make sure that there is enough room to install the device downstream. Please note that room for 2 stop valves (to be installed before and after the GROHE Sense Guard) is needed. We recommend to install the GROHE Sense Guard with a wall mount set to ensure an easy and stable installation (product

# 22501000).

Material needed for installation:

□Adapter for different pipe sizes

□Other material: ___________________________________________________________________________.

1.2 Is there a power outlet available to power the GROHE Sense Guard, located above the water pipe?

The power plug needs to be installed above the level of the water pipe. The provided cable has a length of 70cm. If the length is too short, please make sure to order the extension cable (product #22521LNO) or have an extra power plug installed.

1.3 Is there a stable Wi-Fi signal at the potential location of the GROHE Sense Guard?

First, make sure that:

your smartphone is connected to the internet via Wi-Fi or mobile data.

your router doesn’t have any offline times or shifts to battery saving mode during night.

Please check the Wi-Fi connectivity at this location with your smartphone:

OPTION 1: Download a Wi-Fi analyzer app (e.g. Android: Wi-Fi analyzer, iOS: Wi-Fi SweetSpot) and check for connectivity stability for 5 minutes on the app.

OPTION 2: Use a mobile phone’s connectivity indicator. Check for connectivity stability for a period of 5 minutes.

1.4 Which of the following main heating devices for heating water is installed in the house?

Devices in the water system?	What to do?
□ Flow heater	 Turn off the micro-leakage test later in the device settings of the GROHE
	ONDUS app. With flow heater, the micro-leakage test that is done via
	pressure measurement might not work properly.

□ Central heating  Only install GROHE Sense Guard on a cold water pipe.

 With a central heating system, separate hot and cold water pipes enter the apartment. GROHE Sense Guard cannot be installed on the hot water pipe. Therefore, any leakage on the hot water pipe cannot be detected.

□ Hot water boiler	 Hot water boiler with pressure compensation container:
	 No further changes needed.
	 Hot water boiler without pressure compensation container:
	 Turn off the micro-leakage test later in the device settings of the
	GROHE ONDUS app. With a hot water boiler without a pressure
	compensation container, the micro-leakage test that is done via
	pressure measurement might not work properly.

1.5 Check if the flow pressure is between 0.05 and 1 MPa (0.5 and 10 bar/7 and 145 psi).

GROHE Sense Guard operates ideally with an incoming flow pressure between 0.1 and 0.5 MPa (1 and 5 bar/7 and 145 psi). If you are not sure about the water pressure in the house, please contact your water utility.

1.6 Are any pressure-influencing devices installed downstream of the potential GROHE Sense Guard location?

The GROHE Sense Guard measures the downstream water pressure in the system. All pressure-influencing water appliances need to be installed upstream of GROHE Sense Guard. In case these appliances cannot be installed upstream of the GROHE Sense Guard, the Micro-Leakage detection might be influenced and therefore needs to be turned off. Exception: Upstream the hot water system, backflow preventers / pressure compensation containers are needed to ensure functionality of the GROHE Sense Guard.

Please check for any appliances downstream the potential location of the GROHE Sense Guard that might affect the water pressure.

Devices in the water system?		What to do?

□	Water filters	Guard
□	Backflow preventers	 OPTION 2: No micro-leakage test possible, turn micro-leakage test off
□	Booster pumps	 OPTION 3: Install pressure-influencing devices upstream

□Water softeners

1.7Are any devices installed that have a cyclic or permanent flow of water? (downstream of the potential location of the GROHE Sense Guard)

GROHE Sense Guard measures water flow to detect leakages. If appliances permanently or cyclically consume water this functionality cannot work properly.

Devices in the water system?		What to do?
□ American fridges/permanent ice makers		 OPTION 1, for devices with cyclic water draw off:
□ Aquariums with permanent fresh water flow		 Modify the GROHE Sense Guard settings,
□ Permanent garden drop sprinklers		see instructions below1.
□	Drinking water sprinklers	 OPTION 2, for devices with permanent water draw

		Please note that leakages in pipes that

bypass the GROHE Sense Guard cannot be detected.
