Installation
Flush pipes troroughly!
GROHE recommends installing isolating valves upstream of
the Base Unit to facilitate servicing.
Base Unit
The Base Unit of the system can be installed in the following
orientations: vertically, horizontally front side up, on inclines.
Location suggestions:
1. Under the bath.
2. Above the ceiling.
3. In an adjacent room.
The Base Unit must be screwed down.
Refer to the dimensional drawing on fold-out page I.
1. Align Base Unit (A) horizontally and vertically, then mark out
holes for screws, see fold-out page II, Fig. [1].
2. Drill holes for Base Unit and insert wall plugs (B) if
necessary, see Fig. [2].
3. Fasten Base Unit (A) to wall or floor with screws (C),
see Fig. [3].
Connect the cold and hot water supply pipes to the Ø 15mm
connections of the Base Unit (A), see Fig. [4].
Do not solder the connections.
The hot water supply must be connected to the inlet
marked HOT, the cold water to the inlet marked COLD.
Connect mixed water outlet to the shower set.
For mounting the shower set, refer to the relevant technical
product information.
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 364-7-701-1984 as well as
all national wiring rules!
Connecting to the power supply
Always switch off the power supply before
making electrical connections.
Open cold and hot water supply.
Check the supply pipes and connections to the shower set for
leaks.
Outlet temperature synchronisation
In cases where there is a distance of several metres between
the Base Unit outlet and the shower, compensation for cooling
of water can be carried out using the SYNCHRO function of
the Main Controller, see also technical product information of
the Main Controller.
1. Run the shower at 38 °C for a few minutes.
2. Measure the actual water temperature at the shower outlet.
3. Switch off, enter the setup mode and select SYNCHRO.
4. Adjust the indicated temperature to the same as that
actually measured.
5. Press Pause to confirm.
6. Exit the setup mode.
Main and Remote Controllers
The Main Controller can be installed inside cubicle or over the
bath.
The Remote Controller can be installed inside or outside the
bathroom or in the bedroom.
The maximum installation distance from the Base Unit
(depending on the wall type, thickness and construction)
is 10 metres for both controllers.
The Main and Remote Controllers are not intended as
hand held devices - they must be fitted to the wall using
the brackets supplied.
Refer to the dimensional drawing on fold-out page I.
Decide the best position. Pay attention to electrical wiring and
water lines.
1. Align wall bracket (D) vertically and mark out holes for
screws, see Fig. [5].
2. Drill holes for wall bracket (D) and insert wall plugs (E)
if necessary, see Fig. [6].
3. Fasten wall bracket (D) to wall with screws (F), see Fig. [7].
4. Place controller (G) in the wall bracket (D), see Fig. [8].
5. Secure controller (G) with retaining screw (H).

Maintenance

Check, clean and, if necessary, replace parts.
