Prior to installation
This GROHE fitting can be used in conjunction with
a pressurised storage heater or an instantaneous heater.
Operation with unpressurised storage heaters
( = open water heaters) is not possible.
To ensure correct operation of the fitting, the flow
pressure should be between 1 and 5 bar.
It is recommendable to install a pressure-reducing valve
in the case of higher flow pressures.
In the case of new installations, flush the cold
and hot water lines thoroughly until the water is
completely free of contamination before and
after installation. Otherwise any residues
remaining in the lines may block the fitting and
contaminate the drinking water.
Make sure that you do not damage the fitting
surfaces with the tool during installation. For this
reason, never use toothed pliers.

1 Installation on the worktop: Feed the spray hose A
through the mixer body from above. Push O-ring B
onto the fitting. Insert the fitting through the hole in
worktop C. Fit sealing washer D and mounting set E
from below. Fasten the fitting using nut F.
2 Installation on the sink: Feed the spray hose A
through the mixer body from above. Push O-ring B
onto the fitting. Insert the fitting through the hole in
sink G. Fit support plate H, sealing washer D and
mounting set E from below. Fasten the fitting using
nut F.
Connect pull out spray J without using any additional
3
seals. Fit one side of the stop K and spring L over the
spray hose A from below. Pass the end of the spray
hose A through the other hole in the stop K. Screw
snap coupling M onto spray hose A.
Pull sleeve N of snap coupling M downwards and
4
attach it to union O.
In order to ensure that pull out spray J is correctly
5
seated, lugs P on the outlet must engage in the
groove on the pull out spray J1.
Ensure that you do not bend or twist the fitting
6
pressure hoses.
Screw the fitting pressure hoses with the seal R to the
7
service valves.
Open the cold and hot water supply and check
the connections for watertightness.

Flow rate limitation, Page 4
This fitting is equipped with a flow rate limiter, permitting
an infinitely variable individual reduction in flow rate.
The highest possible flow rate is set at the factory before
despatch.
The use of flow rate limiters in combination with
hydraulic instantaneous heaters is not
recommended.
Lever out the plug S. Remove the set screw T using
0
a 3mm allen key and remove the lever U. Remove the
cap V.
Change the flow rate by turning the adjusting screw
a
using a 2.5mm allen key.
Troubleshooting, Page 2
Fault: Flow rate noticeably reduced or changed spray
pattern
1. Insufficient supply pressure. Check the upstream
installation.
2. Mousseur (46 711) blocked/dirty: Clean or replace the
mousseur. To clean the pull out spray, simply rub with
the fingers.
3. Non-return valve (08 565) blocked / dirty: Clean or
replace the non-return valve.
4. Snap coupling with non-return valve (46 338) blocked/
dirty: Clean or replace the snap coupling.
Fault: Fitting housing leaking
1. Cartridge (46 374) screw coupling (46 759) loose:
Tighten the cartridge screw coupling.
2. Seals at cartridge base damaged or dirt particles on
sealing surfaces. Close the cold and hot water supply.
Check and clean sealing surfaces, or replace
cartridge completely.
3. Impermissible operating conditions, such as hot water
temperature above 80 °C, pressure surges in
upstream installation. Ensure that the operating
conditions are in order. Replace cartridge completely
if necessary.
Please contact your installer in the event of faults not
described here.
Care and recycling
For directions on care, please refer to the accompanying
