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].

950632.book : i95063gb.fm Seite 7 Mittwoch, Oktober 4, 2000 7:42 AM

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.

950632.book : i95063gb.fm Seite 8 Mittwoch, Oktober 4, 2000 7:42 AM

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.
