Grohe 22 513 Manual page 50

• 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.
For more detailed information see online TPI or GROHE
ONDUS app under Menu -> Help -> Frequently asked
questions
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.
Installation,
see page 2 or 3
Prior to installation, the water supply must be disconnected.
GROHE recommends fitting GROHE Sense Guard in
combination with bracket 22 501, available in the GROHE
product range.
Use the filter provided and seal. See page 2, Fig. [1] and
page 3, Fig. [1] and [2].
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.

A function test should be carried out upon installation:
1. Shut off the water supply to the GROHE Sense Guard.
2. Drain off water from the closed pipe system.
3. Use the app to check whether the water pressure falls.
If the water pressure remains constant, then installation has
failed. Check the flow direction.
Follow the set-up instructions on the app.
