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 Foot control 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 Foot control sensing it will be opened, and if the
solenoid valve is already open it will be closed.
Specifications
• Flow pressure:
- min. 0.05 MPa
- recommended 0.1 - 0.5 MPa
• Operating pressure max. 1.0 MPa
• Test pressure 1.6 MPa
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!
• Max. flow 6.6 L/min or 1.75 gpm/0.41 MPa
• Hot water supply temperature: max. 158 °F
- Recommended (energy saving): 140 °F
- Thermal disinfection possible
• Ambient temperature: 39 - 104 °F
• Relative humidity: max. 80%
• Voltage supply: 6 V lithium battery (type CR-P2)
• Rated power: 1.4 W
• Automatic safety shut-off after contact: 60 s
• Three water pulses indicate that a battery change is
necessary.
• Type of protection control: IP 44
• Water connection cold - right
hot - left
Installation
Refer to fold-out page I for hose lengths and installation
dimensions.
Caution: The control should be easily accessible.
Flush piping system prior and after installation of faucet
thoroughly
!
Install faucet, see fold-out page I, Figs. [1] to [6].
Connecting faucet
Install bracket with control and connect, see fold-out pages I
and II, Figs. [7] to [11].
The sensor plate must be mounted on plastic or wooden
surfaces. The distance to metal surfaces must be taken into
account, see Fig. [8].
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 fold-
out page II , Fig. [12].
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. [14].
The spout must always be positioned above the
sink to prevent water damage.
Ensure free runoff.
Insert battery, see fold-out page II, Figs. [13] to [16]. The
sequence is important and must be observed.
The electronics will detect ambient conditions. During this time
the control indicator lamp flashes. The fitting must
not be
activated (for approx. 1 min.).
Check connections for leakage.
Check for proper function , see Fig. [17].
Adjusting of Foot control parameters to ambient conditions,
see fold-out page III, Fig. [18].
- The release varies depending on ambient temperature
and air humidity.
- Foot control parameters: 5 highest value... 1 lowest value...
- A value that is too high leads to the risk of continuous
operation.
The menu is started by pressing the button at the control unit
for at least 10 seconds.
• The indicator lamp flashes once.
• 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.
• The selected level is indicated by the number of flashes.
- If no further buttons are pressed, the indicator lamp signals
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. [19] to [21].
Shower jet diverter see Fig. [21].
Flow rate limitation, see Fig. [22] and [23].
Hygiene flushing , see Fig. [24].
Hygiene flushing serves to ensure water hygiene if the fitting is
not used for a long time.
By initiating the Foot Control function and then pressing the
button at the control unit, a flushing for a period of 10 minutes
takes place.
If the faucet is activated during this period again, the flow
will be stopped, the hygiene flushing failed and has to be
restarted.
