Application
The filter system may only be operated together with an
original GROHE Red boiling water storage heater and fitting.
The filter system measures the flow rate using a sensor and
from this calculates the remaining capacity of the filter
cartridge as a function of the set litre capacity. If the filter
cartridge litre capacity set on the display unit is exceeded, the
values are displayed as negative values.
The sensor also monitors the maximum service life of the filter
cartridge. If the maximum service life of 12 months is
exceeded, the remaining capacity of the filter cartridge flashes.
The filter system reduces the carbonate hardness and must be
used in regions with a carbonate hardness exceeding 12° dH.
The water filtrate is classified as Category 2 according
to EN 1717.

Approval and conformity
This product conforms to the requirements of the
relevant EU guidelines.
The conformity declarations can be obtained from the following
address:
GROHE Deutschland Vertriebs GmbH

Installation
Refer to the dimensional drawing on fold-out page I.
Connect filter head and filter, see technical product
information for the filter head and the filter cartridge and fold-
out page II, Fig. [1]. Note direction of flow.
1. Install pressure hose (A) to the inlet of filter head.
2. Install sensor (B) at outlet of filter head. The sensor (B) must
be installed horizontally.
3. Install display unit (C).
Use suitable screws and wall plugs (not included in the scope
of delivery).
Connect filter system, see Fig. [2].
1. Screw pressure hose (D) onto sensor (B).
2. Screw pressure hose (A) of filter system onto adapter (E)
[Duo] or directly onto cold water connection [Mono].
3. Install the GROHE Red boiling water system as per the
technical product information enclosed with the product.
Do not connect the voltage supply to the GROHE Red
boiling water storage heater yet.
Open cold water supply and check connections for
watertightness.
Set water hardness at filter head, see Fig. [3].
Set water hardness at bypass setting of filter head to local
conditions, see table column A on page III.
The relevant water supplier can provide information on the
water hardness.
0.2 – 0.5 MPa
max. 0.2 – 0.8 MPa
3 V lithium battery (type CR 2032)
The bypass value setted to the filter head must also be set as
litre specification on the display unit (C), see Fig. [4].
Setting the litre specification (factory setting is 600 litre),
see Fig. [4].
The value for the litre specification depends on the water
hardness as per table column B on page III:

Maintenance
Filter
IPX4
See technical product information of filter cartridge for
IPX8
information on replacing the filter cartridge.
Resetting the filter capacity at the display unit (C), see
fold-out page II, Fig. [4].
After a new filter cartridge is inserted, the filter capacity must
be reset as follows:
Button
Display flashing
(negative litre specification, e.g. -1 or
remaining capacity e.g. 150 flashing)
Press RESET button for 3 seconds
(rESEt appears)
The data for time and litre capacity is
reset
Note: The litre specification programmed for the filter cartridge
is retained.
Battery (F), see Fig. [5] and [6].
The battery must be replaced 7 years after commissioning the
fitting, at the latest.
Button
BATT display flashes
(battery is discharged and needs to be
replaced)
1. Loosen screw (G) and remove cover (H), see Fig. [5].
2. Remove battery (F) and replace, see Fig. [6].
Important: Note correct polarity.
Note: No settings saved by the user will be lost when
changing the batteries or if the battery discharges.
Assemble in reverse order.
Disposal note
