Type approvals

The GROHE Red boiling water storage heater

with filter

system must be installed the safety assembly with

expansion

vessel

provided.

The boiling water storage heater

with filter system

may only be
operated together with an original GROHE Red boiling water
fitting.

Application

The GROHE Red boiling water fitting supplies boiling water in
addition to hot and cold tap water. Boiling and mixed water
flows into the GROHE Red fitting through separate pipes and
flows out through two separate areas of the flow straightener.

The GROHE boiling water storage heater is designed to heat
and store drinking water in pressurised systems.

The GROHE boiling water storage heater is suitable for
connection to a mains system with a maximum water pressure
of 0.8 MPa.

It must not be connected to hot water.
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 water filtrate is classified as Category 2 according
to EN 1717.

Safety notes

GROHE Red boiling water storage heater:

This device is not intended for use by persons
(including children) with physical, sensory or mental
impairments or a lack of experience or knowledge in
using devices of this type.

Children must be supervised to ensure that they do
not play with the device.

Risk of electric shock. Avoid damaged power supply
cable. In case of damage, the boiling water storage
heater must be replaced by the manufacturer or its
customer service department or an equally qualified
person.

Caution, risk of scalding! Escaping water is boiling
hot. Never touch the end of the spout in order to
swivel the spout as it becomes extremely hot.

•The boiling water storage heater must be connected
to a permanent power supply with earth wire.

• Installation is only possible in frost-free rooms.

• The boiling water storage heater is only suitable for

indoor use.

• The boiling water storage heater must be placed in an

upright position.

• The boiling water storage heater and plug must not be

directly or indirectly sprayed with water when cleaning.

• The boiling water storage heater must not be opened.

• Use only genuine replacement parts and accessories.

The use of other parts will result in voiding of the warranty
and the CE identification, and could lead to injuries.

If the boiling water storage heater is to be drained, the safety
assembly

with

expansion vessel of the boiling water storage
heater must be removed. Invert the boiling water storage
heater and allow the water to run out.

However, we strongly advise against draining the boiling
water storage heater. There is a significant risk of
damaging the boiling water storage heater.

• Extension cables are not permitted between the electrical

socket and boiling water storage heater connection.

Installation

Refer to the dimensional drawing on fold-out page I.
Installing fitting, see fold-out page II, Figs. [1] and [2].

Insert fitting in sink hole. This will require leading through the
hoses one at a time.

Note: If there is no need to fit support plate (A), the clamping
length may be increased by 15mm, see Fig. [1].

Mount safety relief valve kit to the waste pipe, see Figs. [3]
to [6].

Mount wall holder, see Figs. [7] and [8].
Mount compression couplings (B) and tighten nipple, see

Fig. [9].

Fix expansion vessel (C) with safety assembly to the wall
holder, see Fig. [10].

Connect filter head and filter, see technical product

information for the filter head and the filter cartridge and fold­out page III, Fig. [11]. Note direction of flow.

1. Install pressure hose (D) to the inlet of filter head.

2. Install sensor (E) at outlet of filter head. The sensor (E) must
be installed horizontally.

3. Install display unit (F).

Use suitable screws and wall plugs (not included in the scope
of delivery).

Connect filter system, see Fig. [12].

1. Connect adaptor (G) on the cold-water service valve.

2. Screw pressure hose (D) of filter system onto adapter (G).

3. Screw hose (H) onto sensor (E).

Connect storage heater, see Figs. [2] and [13].
Install storage heater taking into consideration the

available hose lengths.
Do not connect voltage supply yet.

Flush pipes thoroughly before and after installation

(observe EN 806).

1. Connect expansion vessel (C), see Fig. [13].

2. Screw hose (H) to expansion vessel (C).

3. Screw storage heater pressure hose (I) marked blue to
expansion vessel (C) using the seals provided.

4. Connect copper pipe (not in the scope of delivery) to
the Ø15mm compression connection (J) of the expansion
vessel (C) and tighten.

Connecting fitting, see fold-out page III, Fig. [14].

1. Screw fitting pressure hose (K) marked blue to adapter (G).

2. Screw red marked pressure hose (L) of the fitting onto the
hot-water service valve.

3. Connect the fitting pressure hose (M) marked 99 °C to
connection (N) on the storage heater.

Open the service valve and check connections for
watertightness.

Filling storage heater with water, see Figs. [15] and [16].

1. Pull button (O1) on handle (O) of fitting outward and turn the
handle anti-clockwise, see Fig. [15].

2. Fill the storage heater until water comes out the spout of
the fitting.

3. Connect voltage supply via mains plug (P), see Fig. [16].

4. Press and hold button (Q) on storage heater for at
least 2 seconds to switch on the storage heater. The red
indicator lamp (Q1) indicates that the storage heater is
switched on.

Important!
The spout must not be fitted with any downstream

resistances in the form of air bubblers (e.g. mousseurs) or
components reducing flow (e.g. restrictors) as these will
result in damage to the storage heater.

Set water hardness at filter head, see fold-out page IV,

Fig. [17].
Set water hardness at bypass setting of filter head to local
conditions, see table column A on page 4.
The relevant water supplier can provide information on the
water hardness.
The bypass value setted to the filter head must also be set on
the display unit (F), see Fig. [18].

Setting the litre specification (factory setting is 600 litre),
see Fig. [18].
The value for the litre specification depends on the water
hardness as per table column B on page 4:

The GROHE Red boiling water system is now fully
installed and ready for operation.

disconnect the mains plug.

Wait until the storage heater and fitting have cooled down.
Open the lever to depressurise the storage heater.

Inspect and clean all parts, replace as necessary and lubricate
with special grease.

I. Filter

See technical product information of filter cartridge for
information on replacing the filter cartridge.

Resetting the filter capacity at the display unit (F), see fold­out page IV, Fig. [18].
After a new filter cartridge is inserted, the filter capacity must
be reset as follows:

Note: The litre specification programmed for the filter cartridge
is retained.

Battery (F1), see fold-out page IV, Fig. [19] and [20].
The battery must be replaced 7 years after commissioning the
