Prior To Installation - Grohe Start Eco 23 269 Manual De Instrucciones

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.
Never install shut-off valves in the outlet pipe
(mixed water) downstream of any concealed
mixer.

Drill the hole for the fitting and cut the slots for the
pipes in the installation wall.
Align the fitting using a spirit level. The arrows on the
1
fitting template A must point upwards.
Install the fitting using the fitting template B. Ensure
2
that the finished surface of the wall C lies within the
area X of the fitting template.
Apply sealing compound at the cold, hot and mixed
3
water connection pipes in accordance with their
overall installation. Screw the connection pipes into
the fitting body before installing the fitting.
- Attach the connecting pipes to the overall installation.
Note that soldered connections are not
permitted as otherwise built-in seals may be
damaged.
Open the cold and hot water supply and check
the connections for watertightness.
- Shut off the hot and cold water supply again.
- Only remove the fitting template for final
installation.
- Plaster and tile the wall.
Flow rate limitation, Page 2
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.
Change the flow rate by turning the adjusting screw
4
using a 2.5mm allen key.
Final installation, Page 2
Screw on the cap D with the seal. Grease the seal E.

Push on the escutcheon F and secure it with
screws G.
If you cannot push the escutcheon far enough onto
the cap D, you must install an extension, see
Replacement Parts, Page 1 (46 191 = 25mm
or 46 343 = 50mm). If the wall surface is uneven, the
top edge of the escutcheon must additionally be
sealed with silicone.
Fit the insulator H onto the cartridge switch lever and
6
secure it using the screw I.
Fit the lever J and fasten it with the loosely fitted set
screw K and insert the plug L.
Operate the fitting as shown.

Troubleshooting, Page 1
Fault: Flow rate noticeably reduced
1. Insufficient supply pressure:
Check the upstream installation.
Fault: Fitting housing leaking
1. Cartridge (46 048) screws loose: Tighten the cartridge
screws alternately.
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
