Technical Data
F
unctioning Principle
T
his Avensys mixing valve is a thermostatic
m
ixer with wax cartridge. Turning the shut-
o
ff lever in a counter-clockwise direction
o
pens the water flow. Turning the tem-
p
erature cross 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. The product is preassembled.
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
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
Exposed Installation
T
his thermostatic shower mixing valve is to
b
e installed with the outlet at the top for use
w
ith the headshower.
I
f there is a pressure differences between
t
he hot and cold water supply install
a
ttached flow limiters in the water
c
onnection elbows, see table below.
xScrew out connection elbows (A), see
Fig. [1].
xInstall flow limiters (B) in accordance to
table above with threaded rings (C) by
using a 12mm socket spanner.
T
he thermostatic mixing valve is fixed to the
w
all via the backplate and connected to the
s
upply pipes by a pair of elbows. The elbows
a
re preassembled to the valve body. The
v
alve body is fixed to the backplate by a set
s
crew.
In case of exposed installation with supply
pipes from above or below rotate inlet
elbows 90qand connect to 15mm supply
pipes.
1.Loosely screw on nuts (A1) with com-
pression rings (A2), see Fig. [2].
2.Ensure that the projections of the supply
pipes, (i.e. exposed beyond the wall sur-
face) have the correct length (13 - 18mm
)
and distance (150mm).
3.Place the valve body (E) with the elbows
and backplate (D) to the supply pipes.
4.Loosen set screw (D1), see Fig. [3].
5.Remove valve body (E) from supply pipe
s
and hold backplate (D) in position.

10.Slide the valve body (E) with elbows an
d
compression nuts loosely over the
supply pipes.
The body must touch the backplate.
If
not, check pipes for length again.
11. Fix the valve body (E) to the back-
plate (D) by tightening set screw (D1).
Do not use excessive force to tighten
the set screw (D1).

Adjustment
T
he temperature of the outflowing water is
f
actory set to 43 qC. A temperature adjust-
m
ent is necessary if:

measured at the outlet varies from
the factory set temperature.
xAfter any maintenance operation on the
thermostatic cartridge.
F
or temperature adjustment please
p
roceed as follows:
1
.Turn the shut-off lever counter-clockwise
to fully open position and open water flow.
2
.Turn the temperature cross handle
counter-clockwise to maximum hot water
temperature.
3
.Lever out cap (M), see fig. [10].
4.Unscrew screw (N).
5.Pull off temperature cross handle (O).
6.Check the temperature of the outflowing
water with a thermometer, see Fig. [11].
7.Push on temperature cross handle and
adjust temperature to 43 qC.
Turn clockwise (to reduce temperature) o
r
counter-clockwise (to increase
temperature).
8.Pull off temperature cross handle (O) and
reinstall in hot water position as describe
d
in Fig. [10] in reversed direction.
