Safety notes
Prevent danger resulting from damaged voltage supply cables.
If damaged, the voltage supply cable must be replaced by the
manufacturer or his customer service department or an equally
qualified person.
• Installation is only possible in frost-free rooms.
• The optional voltage supply unit is only suitable for indoor use.
• The plug-in connectors must
not
be directly or indirectly sprayed with
water when cleaning.
• The voltage supply must be separately switchable.
• 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.
Application
Thermostatic mixers are designed for hot water supplies from pressurised
storage heaters and offer the highest temperature accuracy when used in
this way. With sufficient power output (from 18 kW or 250 kcal/min),
electric or gas instantaneous heaters are also suitable.
Thermostats cannot be used in connection with unpressurised storage
heaters.
All thermostats are adjusted in the factory at a flow pressure of 0.3 MPa
on both sides.
Operating conditions
The maximum permissible distance between the digital controller/diverter
of the functional unit and the transceiver is 5 m. The best wireless
reception is achieved when the transceiver is surface-mounted.
Sources of interferences
The transceiver operates in the ISM-frequency range (2.4GHz). The
installation in the vicinity of equipment with the same channel occupancy
(eg wireless devices, RF components, etc. [observe the manufacturer´s
documentation!]) should be avoided.
Obstructions/barriers
For operation under adverse environments, in buildings / rooms with
reinforced concrete walls, steel and iron frame, or near of obstructions
(eg furniture) of metal, the radio reception can be disturbed and
interrupted.

Electrical installation
Electrical installation work must only be performed by a
qualified electrician. This work must be carried out in
accordance with the regulations to IEC 60364-7-701
(corresponding to VDE 0100 Part 701) as well as all national
and local regulations.
Rough installation
•
The functional unit must be accessible for maintenance work,
Required dimensions inspection chamber, see fold-out page II, Fig. [1]
to [3].
To simplify the maintenance, GROHE recommends the installation of
isolating valves and detachable connections in the inspection chamber.
• The plug-in connectors and the transceiver
must
be accessible.
• The functional unit must
not
be installed with the lid facing downwards.
• A vacant tube
must
be used to connect the functional unit to the voltage
supply unit and to the transceiver.
Prepare the wall for the installation, refer to the dimensional drawing on
fold-out page I and Figs. [1] to [3] on fold-out page II.
- Prepare holes for the functional unit as well as slots for the pipes and
empty conduit.
Flush pipes thoroughly before and after installation
(observe EN 806)
.
Install functional unit,
see fold-out page II, Figs. [4] to [7].
- Route the mixed water outlet to the points of discharge,
outlet 1 must
be engaged mandatory,
see Fig. [5].
Do not solder the connections.
- For sealing a unused outlet the supplied plug (A) can be used.
Flush the functional unit,
see fold-out page II, Fig. [8] and
fold-out
page III, Figs. [9] and [10].
Close the cold and hot water supply. Assemble in reverse order.
Final installation
Insert batteries into digital controller/diverter,
see fold-out page III,
Figs. [11] to [15]. Grease seals. Insert batteries with correct polarity.
The digital controller/diverter is registered with the functional unit in the
factory.
Secure digital controller/diverter,
see Fig. [16a] or [16b] to [19].
Open the hot and cold water supply and check that the connections
are watertight.
Establish voltage supply via voltage supply unit
(not included in the
scope of delivery),
see fold-out page IV, Fig. [20].
The indicator lamp (B) of the transceiver then flashes one after another
blue, green and red.
The buttons of the digital controller/diverter are now inoperative for 3
minutes.
