Maintenance And Cleaning - Grohe 31 727 Bedienungsanleitung

Technical data fitting:
• Flow pressure:
• Operating pressure:
• Test pressure:
To comply with noise levels if static pressure exceeds 5 bar, a
pressure reducing valve must be fitted.
Avoid major pressure differences between hot and cold water
supply.
• Flow rate at 3 bar flow pressure:
• Temperature
– Hot water inlet:
– Recommended (energy saving):
Water connection:
Thermical disinfektion of the fitting is possible.
GROHE Watersystems app and connection to the
internet
An under-sink device connected to the Internet via Wi-Fi can be
integrated and configured in the GROHE Watersystems app. This
app can be used to deliver messages in the form of push
notifications.
A WLAN router with internet access
(2.4 GHz, IEEE 802.11b/g/n) is required.
Only WLAN channels 1 – 11 can be used.
Installation of the app:
Apple: Android:
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 and commissioning
Flush pipes thoroughly before and after installation
(observe EN 806)!
Adjust bypass of filterhead according to local carbonate
hardness and connect filter cartridge.
The carbonate hardness can be tested by using the enclosed test
strip or the relevant water supplier can provide information on the
carbonate hardness.
Note: Make sure that the water inlet hose does not come loose
by movement when installing the under-sink device.
When transporting or installing the under-sink device,
cooling fluid may have run into the lines.
In order to ensure that the cooling fluid has run back, the
cooler/carbonator may only be installed following a pause
of 24 hours.
When carbonate hardness 9° the use of activated carbon filter
(Order no.: 40 547) is recommended.
The under-sink device is set for operation with the S-size filter
cartridge (prod no.: 40 404) at the factory.
0.2 – 0.9 MPa
For operation with another filter cartridge, the under-sink device
max. 1 MPa
must be adjusted accordingly.
Note:
1.6 MPa
In order to prevent incorrect operation and for protection against
injury, we recommend affixing the sticker provided.
approx. 5,6 l/min
CAUTION!
Risk of damage!
max. 70 °C
60 °C
Always disconnect the power supply and interrupt the CO
cold - right
supply before carrying out maintenance work on the
hot - left
system. The plug-in connector can then be disconnected.
Clean under-sink device
For hygienic reasons, GROHE recommends cleaning the
under-sink device every time the filter is changed or at least
once a year. Cleaning must be performed before changing the
filter cartridge, in order to prevent contamination of the
replacement filter cartridge.
GROHE recommends removing dust from the dust filter for the air
supply at the rear of the under-sink device after each cleaning
operation.
Note: The cleaning kit (Prod. no.: 40 434) and the accompanying
adapter (Prod. no.: 40 694) can be ordered at
www.shop.grohe.com.
If work is performed on mains power supply or in case of
any maintenance work, the GROHE under-sink device
must be bled as otherwise blasts of steam could form as a
result.
• Draw off boiling water from the storage heater until just cold water
flows.
• Close the service valve and disconnect the mains plug.
• Open the tap lever handle to depressurise the storage tank.
• Draining the storage tank (not required each time maintenance is
performed)
Remove the cap on the under-sink device and empty the storage
tank via the drain plug (underside of the device).
• Inspect and clean all parts, replace as necessary and lubricate
with special fitting grease.
Service
The GROHE under-sink device may only be repaired by GROHE
customer service.
Environment and recycling
For reasons of hygiene, it is not possible to recycle used filter
cartridges. Used filter cartridges can be disposed of hazard-free as
residual waste.
In the European Union, you can send the filter including the
hygiene cap back to GROHE for recycling.
