Safety notes
• Installation is only possible in frost-free rooms.
• The plug-in connectors must not be directly or indirectly
sprayed with water when cleaning.
Application
Can be used in conjunction with:
• Pressurised storage heaters
• Thermally/hydraulically controlled instantaneous water heaters
Operation with unpressurised storage heaters (displacement
water heaters) is not possible.
• The GROHE touch function for switching the water flow on
or off is based on the principle of electrical charge shifting on
metallic surfaces. If the solenoid valve is closed during touch
sensing it will be opened, and if the solenoid valve is already
open it will be closed.

Specifications

• Flow pressure:
- min.
- recommended
• Operating pressure
• Test pressure
A pressure reducing valve must be fitted in the supply line if
static pressures exceed 0.5 MPa to satisfy noise level ratings.
Avoid major pressure differences between cold and hot water
supply!
• Flow rate at 0.3 MPa flow pressure
- Shower spray:
- Mousseur:
• Temperature hot water inlet:
Recommended (energy saving):
• Thermal desinfection possible
• Ambient temperature:
• Relative humidity:
• Voltage supply: 6 V lithium battery (type CR-P2)
• Rated power:
• Automatic safety shut-off after contact:
• Three water pulses indicate that a battery change is
necessary.
• Type of protection control:
• Water connection

Installation
Refer to fold-out page I for hose lengths and installation
dimensions.
Caution: The control should be easily accessible.
Flush pipes thoroughly before and after installation
(observe EN 806).
Install the fitting, see fold-out page I and II, Figs. [1] to [9].
Connecting the faucet
Install bracket with control and connect, see fold-out page II,
Figs. [10] to [14].
Install weight on shower hose, see Fig. [15].

Important note
To ensure proper functioning when using metal sinks,
the sink must be connected to the control via the pre-
assembled yellow hose for potential equalisation,
see Fig. [16].
For all other sinks the yellow hose must be connected to
another suitable metal part for potential equalisation.
Country specific and local regulations must be
observed.
Putting into service
To prevent the risk of scalding, the outlet
temperature of the mixer unit should be set to
lukewarm.
Recommended maximum temperature: 38 °C,
see Fig. [18].
The spout must always be positioned above the
sink to prevent water damage.
Ensure free runoff.
Insert battery, see fold-out page II, Figs. [17] - [20].
0.05 MPa
The sequence is important and must be observed.
0.1 - 0.5 MPa
The electronics will detect ambient conditions. During this time
max. 1.0 MPa
the control indicator lamp flashes. The fitting must not be
1.6 MPa
activated (for approx. 1 min.).
Check connections for watertightness.
Check for proper function, see Fig. [21].
Adjusting of touch parameters to ambient conditions,
approx. 9 l/min
see fold-out page III, Fig. [22].
approx. 11 l/min
- The release varies depending on ambient temperature
max. 70 °C
and air humidity.
60 °C
- Touch parameters: 5 highest value... 1 lowest value...
- A value that is too high leads to the risk of continuous
4 - 40 °C
operation.
max. 80%
The menu is started by pressing the button at the control unit
for at least 10 seconds.
1.4 W
• The indicator lamp flashes once.
60 s
• The last stored value will then be displayed by flashing,
e.g. three times for level 3 (factory setting).
• Each time the button is pressed the value goes up one level.
IP 44
• The selected level is indicated by the number of flashes.
cold - right
- If no further buttons are pressed, the indicator lamp signals
hot - left
the last set value 2 more times. The lamp then emits a
continuous signal and the menu is exited. The last stored
value will be saved.
Operation, see fold-out page III, Figs. [23] to [26].
By touching the areas depicted in grey water can be drawn
without using the lever, see Fig. [23].
Note: Activation only by skin contact.
If the flow rate in the touch function is too high, exchange non-
return valve 08 565 with 64 689, see fold-out page II, Fig. [13]
and fold-out page IV.
Shower jet diverter see Fig. [26].
Flow rate limitation, see Fig. [27] and [28].
Cleaning mode, see Fig. [29].
Cleaning mode is started by grabbing the faucet for more than
5 seconds.
• Confirmation via a water pulse.
• In cleaning mode (approx. two minutes) the indicator lamp
flashes twice at the beginning and twice at the end of the
cleaning mode cycle.
Hygiene flushing, see Fig. [30].
Hygiene flushing serves to ensure water hygiene if the fitting is
not used for a long time.
By touching the faucet and then pressing the button at the
