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.

rod into the fitting and screw it to the bottom part
B
or
install the retractable chain set.

3
Ensure that you do not bend or twist the fitting
pressure hoses.
4
Screw the fitting pressure hoses with the seal
H
to the
service valves.
5
Install the pop-up waste.
Seal the rim
J
to the basin using sealing
compound (available in specialist shops) and
the enclosed O-ring
K
.

Press the ball-joint rod
K
of the pop-up waste
downwards. Insert the bottom of the lift rod
B
into the
hole in the hinged socket
M
and press downwards
until the stop is reached. Tighten the screw(s)
N
while
holding the bottom part of the lift rod
B
in a vertical
position.
Open the cold and hot water supply and check
the connections and the pop-up waste for
watertightness.
6
Operate the fitting as shown.
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.

Fault:
Flow rate noticeably reduced or changed spray
pattern
1. Insufficient supply pressure: Check the upstream
installation.
2. Mousseur (13 961/48 159) blocked/dirty: Clean or
replace the mousseur.
Fault:
Fitting housing leaking
1. Cartridge (46 374/46 580) screw coupling
(46 460/46 715) 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.
For directions on care, please refer to the accompanying
Care Instructions. Observe the valid national regulations
when disposing of the fitting.
