Technical Data
F
unctioning Principle
T
his Avensys mixing valve is a thermostatic
m
ixer with wax cartridge. Turning the shut-
o
ff handle in a counter-clockwise direction
o
pens the water flow. Turning the tem-
p
erature handle in a counter-clockwise
d
irection sets the temperature from cold to
h
ot.
T
his product is supplied with connectors to fit
ø
15mm pipework. Connection should be hot
l
eft, cold right as viewed from the operating
p
osition.
P
lumbing Systems
T
his thermostatic mixing valve is suitable for
i
nstallation with:
xGravity-fed plumbing systems with an
open vented hot water cylinder
xCold water storage cistern
xMains pressure unvented and instantan-
eous thermal hot water storage systems
xMulti-point gas water heaters
xCombination boilers with a modulating hot
water output
To maintain sufficient hot water output
ensure the combination boiler temperature
setting is on high.
S
upply Pipework
E
nsure the supply pipework is thoroughly
f
lushed before installing the mixing valve.
G
ROHE recommends installing isolating
v
alves upstream of the mixing valve for
s
ervicing purposes.
N
ew Water Regulations
T
his GROHE-product should be installed to
c
omply with the New Water Regulations
c
overing backflow prevention. It must also
b
e installed in accordance with local bye-law
r
equirements.

Installation
Rough Installation
T
he thermostatic shower mixing valve can
b
e installed in two different ways. The mixing
o
utlet can be at the bottom for use with a
h
andshower or at the top for use with a
h
eadshower.
T
he concealed thermostatic shower mixing
v
alve is supplied with a bracket.
xWith bracket mounted from the front the
valve can be used for installation into solid
and dry-lined walls.
xWith 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.
S
olid and dry-lined walls
D
etermine the route for the incoming hot and
c
old water supply and for the outlet pipe-
w
ork in accordance with the thermostatic
s
hower mixing valve.
1
.Mark a 150mm 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 an
d
cold water supply and for the outlet pipe-
work in accordance with the thermostatic
shower mixing valve.
1.Mark a 150mm diameter hole for the valv
e
and mark the fixing hole positions for the
bracket (A), see Fig. [3].

the hot and cold water supply install
attached flow limiters (F) or spacers (F1)
in the hot andcold water connection inlets
,
see table below.
For reversed supplies installation the
complete mixing valve must be rotated 180q
.
Therefore stop ring must be dismounted,
rotated 180qand reinstalled with catch on
top.

Care
Trouble Shooting
W
e want to ensure that you get long-lasting
s
atisfaction and pleasure from your GROHE
f
itting. Therefore, please read the following
c
are instructions because damage to the
s
urface and underlying material resulting
f
rom improper treatment is not covered by
g
uarantee.
D
o not use any abrasive sponges or scou-
r
ing agents for cleaning. We also advise not
t
o use cleaning agents containing solvent or
a
cid, limescale removers, household vinegar
a
nd cleaning agents with acetic acid. They
a
re aggressive to the surface and will leave
your fitting dull and scratched. As the for-
mulations of commercially available cleanin
g
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 mois
t
cloth only, then simply rinse off and wipe dry
.
You can avoid lime spots by drying the fittin
g
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.
