Grohe SENSE GUARD 22 503 Manual De Instrucciones página 8

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 22 603, available in the GROHE
product range.
It is essential that the provided screen 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.
Before and after the GROHE Sense Guard, a shut-off valve
must be installed.
If further components are installed, please note the correct
installation position:
Water meter unit Filter
For further components like water softener please observe the
special notes in GROHE Sense Guard Individual Installation
Guide. 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.
Pressure-
reducing GROHE Sense Guard
valve
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:
• Operating pressure:
• Test pressure:
• Flow rate:

• Rated surge voltage:
• Temperature for ball impact test:
The test for electromagnetic compatibility (interference
emission test) was performed at the rated voltage and rated
current.
