Installation

Prior to installation, go through the individual installation

guide and read the instructions in full!

Installation, see page 2 or 3

Prior to installation, the water supply must be disconnected.

GROHE recommends the installation of the GROHE Sense

Guard downstream of a whole house water filter system.

In the case that other pressure effective devices are installed

at the premises it is required that the GROHE Sense Guard is

installed downstream of those devices. Pressure effective

devices could include but are not limited to pressure reducers,

booster pumps or water softeners.

Failure to comply with the above recommendation may

adversely affect the microleakage measurement of the

GROHE Sense Guard.

GROHE recommends fitting GROHE Sense Guard in

combination with bracket 22 501, available in the GROHE

product range.

It is essential that the provided filter and seal are used, see

page 2, Fig. [1] and page 3, Fig. [1] and [2]. The use of other

materials, such as hemp, will result in leakage.

Observe the prescribed sequence when fastening the nuts.

See page 3, Fig. [1] to [3].

Observe the correct installation position.

Observe the fitting sequence for other components:

Leakage protection is provided as soon as GROHE Sense

Guard is connected to the power supply.

If the GROHE Sense Guard does not have a power supply, it

cannot shut off the water supply.

Applications

The GROHE Sense Guard constantly checks water

consumption, flow rate and temperature and stores collected

data on the device and in online storage (GROHE Ondus

cloud).

Through constant monitoring, leakages are detected in good

time and water damage can be reduced by using automatic

shut-off or smartphone warnings.

A 100% protection against water damage cannot be

guaranteed for system-related reasons.

GROHE Sense Guard detects everyday water consumption

and saves this as consumption data. On this basis GROHE

Sense Guard responds to unusual situations.

There are many types of possible deviations:

• Pipe burst: an excessively large amount of water flows

through the GROHE Sense Guard. The water supply is

immediately shut off and a push notification is sent to the

connected smartphone.

• Unusual water consumption: if a lot of water is taken in one

discharge operation or there are small flow rates over

several hours, a push notification is sent to the connected

smartphone. In addition, the consumption is constantly

measured and additional tests are carried out several times

each day.

• Micro leakage: minute quantities of water leak out and a

push message is sent to the interconnected smartphone.

The micro-leakage test is carried out once every 24 hours.

In the event that the measurement could not be completely

carried out multiple times, a notification is likewise sent.

The results of the measurement may be influenced by the

characteristics of the pipe system or overlapped tapping

processes.

The speed of detection depends on the previous

consumption behaviour of the household, the length and

type of the pipe system and the water flow rate and

pressure.

In order to increase the detection speed of the leaks, a flood

sensor (available in the GROHE product range) can

additionally be used. If water flooding is detected, this sends

an optical or acoustic alarm signal and sends a message of

the detected event to the GROHE ONDUS app and GROHE

Sense Guard, following which the water supply is

automatically shut off. It must be ensured that both devices

have a stable internet connection.

Operating conditions

Interference sources

The transmitter/receiver unit operates in the ISM frequency

band (2.4 GHz). Installation in proximity to devices with the

same frequency band (e.g. WLAN devices, HF components,

etc. [observe manufacturer documentation!]) should be

avoided.

Obstructions/barriers

Wireless reception can be impaired and interrupted under

unfavourable surrounding conditions, in buildings/rooms with

reinforced concrete walls, steel and iron frames or in proximity

to obstacles (e.g. furniture) made of metal. Where necessary,

a WLAN repeater must be connected to the main router in

order to increase the range of the radio signal.

Technical data

• Flow pressure: min. 0.05 MPa /

recommended: 0.1–0.5 MPa

• Operating pressure: max. 1 MPa

• Test pressure: 1.6 MPa

• Flow rate: 2–85 l/min

• Water temperature: 3 °C–40 °C

• Ambient temperature: 3 °C–40 °C

• Voltage supply: DC 12 V 2.5 A

• Power consumption: 30 W

• A pressure-reducing valve must be fitted in the supply line if

static pressures exceeds 0,5 MPa to satisfy noise level

ratings.
