Technical Data
Functioning Principle
The Grohsafe pressure balance valve is a
safety mixer designed to compensate for
fluctuations in the water supply pressures,
which would otherwise affect the mixed
water temperature.
This product is supplied with connectors to fit
ø 15mm pipework. Connection should be hot
left, cold right as viewed from the operating
position. The product is preassembled, as
standard, with the outlet up.
For bottom outlet installation refer to
page 7 and 10.
Plumbing Systems
Suitable for use with multi-point gas water
heaters or combination boilers with a modu-
lating hot water output. To maintain sufficient
hot water output ensure the combination
boiler temperature setting is on high. Also
suitable for mains pressure unvented and
instantaneous thermal hot water storage
systems.
Not suitable for instantaneous hot water
displacement heaters or gravity-fed plum-
bing systems with an open vented hot water
cylinder and cold water storage cistern.
Supply Pipework
Ensure the supply pipework is thoroughly
flushed before installing the mixing valve.
GROHE recommends installing isolating
valves upstream of the mixing valve for
servicing purposes, and in-line strainers to
prevent the ingress of water borne debris.
New Water Regulations
This GROHE-product is designed to comply
with the current Water Bylaw 17 and the new
Water Regulations covering back-flow pre-
vention. It must be installed in accordance
with local authority bye-laws. Incorrect instal-
lation could contravene bye-law installation
requirements.

Installation
Rough Installation
The pressure balance shower mixing valve
can be installed in two different ways. The
mixing outlet can be at the bottom for use
with a handshower or at the top for use with
a headshower.
The standard position is outlet up, if you
want to have the outlet down please refer to
chapter "Bottom Outlet Installation" on
page 11.
The concealed pressure balancing valve is
supplied with a bracket.
• With bracket mounted from the front the
valve can be used for installation into solid
and dry-lined walls.
• With bracket mounted from behind the wall
the valve can be used for installation into
the front face of a stud partition wall
structure or the rear face of a shower
cubicle or laminated panel.
Solid and dry-lined walls
Determine the route for the incoming hot and
cold water supply and for the outlet pipe-
work in accordance with the pressure
balance valve pressure balancing valve.
1.Mark a 160mm diameter hole for the valve
and mark the fixing hole positions for the
bracket (A), see Fig. [1].
2.Drill 6mm diameter holes and insert the
supplied wallplugs (A1), see Fig. [2].
3.Remove the plaster and brick or block.
Laminated panel walls
Determine the route for the incoming hot and
cold water supply and for the outlet pipe-
work in accordance with the pressure
balance valve.
1.Mark a 160mm diameter hole for the valve
and mark the fixing hole positions for the
bracket (A), see Fig. [3].

Installation
Preassemble Valve
1.Remove the two screws (B1) from the
fitting template (B), then remove the
template, see Fig. [4].
2.Install concealed pressure balance val-
ve in wall and thread the compression
fitting (C) into the valve body by use of
an additional sealing compound, see
Fig. [5].
2.Place the backplate (D) onto the mixer
body (E). Make sure that the locating pins
on the valve body slot into the apertures
on the back plate, see Fig. [6].
3.Screw backplate (D) to bracket (A) with
fixing screws (D1).
4.Fix the valve body (E) to the backplate (D)
with clips (F) and screws (F1).
Do not use excessive force to tighten the
screws (F1).
5.Align the valve with the bracket horizon-
tally, vertically and parallel to the wall by
using a spirit level.

Installation
6.Slide the compression nut (C1), then the
ring (C2), over the pipe. Insert the pipe
ends into the openings of the inlet and
outlet connectors of valve body. Then slide
the rings (C2) and nuts (C1) into place and
tighten the compression nuts (torque min.
20 Nm), see Fig. [7].
7.Fix valve (E) with bracket (A) to wall by
using supplied screws (A1).
The hot water supply must be connected on
the left and the cold water supply on the
right. In case of reversed supply pipes refer
to chapter "Reversed Supplies Instal-
lation" on page 12.
Important:
Shut off valves must not be installed in the
outlet (mixed water line) of this concealed
Pressure Balancing Valve.
Open hot and cold water supply.
Check the pipework and connections to the
pressure balance valve for leaks.
Reinstall fitting template for finishing wall
surface.
8.Observe the installation depth in accor-
dance with the instructions given on the
fitting template, see Figs. [8] for Head-
shower and [9] for Handshower.
9.Fitting template must remain intact for
finished wall surface measurements and
as a template for plastering and / or tiling.
On tiled wall surface grouting must be
either flush or raised for proper sealing of
gasket on the wall plate.
On prefabricated walls, it is recommended
to use sealant around the wall plate to
prevent water condensation from seeping
into wall.
Plaster and tile the wall.
Do not remove fitting template before
installation is completed.

Installation
Wall Plate Installation
1.Remove the two screws (B1) from the
fitting template (B), then remove the
template, see Fig. [10].
2.Turn the driver (G) clockwise to the OFF
position, see Fig. [11].
3.Install two of the four screws (H1) into the
valve cover (J). These screws allow for
variation in wall thickness when mounting
the wall plate.
4.Line up the screw heads with the pre-cut
notches in the center of the wall plate (H).
5.Slide the wall plate (H) over the screw
heads and rotate the wall plate counter-
clockwise until it is vertically aligned, see
Fig. [12].
Additionally seal the top edge of the wall
plate with silicone if it is fitted against a
particularly rough surface (deep tile joints,
highly textured tile).
6.Tighten the wall plate screws.
7.Push adjustable hot water limit stop (K)
to the intermediate ring (M) as described in
Fig. [13].
Please refer to chapter "Maximum Hot
Water Limit Setting" on page 13 for
limiting maximum outlet temperature.
8.Push the handle (L) on the intermediate
handle (M) so that the "OFF" position on
the wall plate is in alignment with the arrow
on the handle.
9.Tighten handle (L) with screw (L1) and
cover with cap (L2).
The pressure balancing valve is now ready
for use.
If the pressure balancing valve is in-
stalled too deep, the fitting depth can be
increased by 25mm with an extension set
(see spare parts page 3, 4 and 5, item 13).

Care
Trouble Shooting
We want to ensure that you get long-lasting
satisfaction and pleasure from your GROHE
fitting. Therefore, please read the following
care instructions because damage to the
surface and underlying material resulting
from improper treatment is not covered by
guarantee.
Do not use any abrasive sponges or scou-
ring agents for cleaning. We also advise not
to use cleaning agents containing solvent or
acid, limescale removers, household vinegar
and cleaning agents with acetic acid. They
are aggressive to the surface and will leave
your fitting dull and scratched. As the for-
mulations of commercially available cleaning
agents frequently change, we cannot gua-
rantee they will provide the gentle care our
fitting deserves.
Clean the fitting with a little soap and a moist
cloth only, then simply rinse off and wipe dry.
You can avoid lime spots by drying the fitting
each time it is used. If lime deposits do oc-
cur, remove them with Grohclean (ref. no.
18 078), our environment-friendly cleaning
liquid. Grohclean is specially formulated to
gently clean the surface of our fittings.
