Technical Data
Functioning Principle
This Avensys mixing valve is a thermostatic
mixer with wax cartridge. Turning the shut-
off handle in a counter-clockwise direction
opens the water flow. Turning the tem-
perature handle in a counter-clockwise
direction sets the temperature from cold to
hot.
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.
Plumbing Systems
This thermostatic mixing valve is suitable for
installation with:
•Gravity-fed plumbing systems with an
open vented hot water cylinder
•Cold water storage cistern
•Mains pressure unvented and instantan-
eous thermal hot water storage systems
•Multi-point gas water heaters
•Combination boilers with a modulating hot
water output
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.
New Water Regulations
This GROHE-product should be installed to
comply with the New Water Regulations
covering backflow prevention. It must also
be installed in accordance with local bye-law
requirements.
Specification

Installation
Exposed Installation
The thermostatic 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.
If there is a pressure differences between
the hot and cold water supply install
attached flow limiters in the water
connection elbows, see table below.
•Screw out connection elbows (A), see
Fig. [1].
•Install flow limiters (B) in accordance to
table above with threaded rings (C) by
using a 12mm socket spanner.
The thermostatic mixing valve is fixed to the
wall via the backplate and connected to the
supply pipes by a pair of elbows. The elbows
are preassembled to the valve body. The
valve body is fixed to the backplate by a set
screw.
In case of exposed installation with supply
pipes from above or below rotate inlet
elbows 90°and 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 pipes
and hold backplate (D) in position.

Installation
6.Mark the holes in the backplate for wall-
plugs, see Fig. [4].
7.Drill the holes (6mm) for the wallplugs (F)
and fit them into the wall, see Fig. [5].
8.Fix the backplate (D) with set screw (D1)
on top or bottom to the wall with
screws (G), see Fig. [6].
9.Slide the escutcheons (H) over the
supply pipes and install filters (J), see
Fig. [7].
10.Slide the valve body (E) with elbows and
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).
12.Tighten the compression nuts (torque
min. 20 Nm), see Fig. [8].

Installation
Pipe Connection
1.Close free outlet with plug (K), see Fig. [9].
2.Thread the outlet nipple (L) with the O-ring
seal into the valve body outlet.
3.Insert pipe and tighten outlet nipple (L).
Open hot and cold water supply.
Check the pipework and connections to the
thermostat mixing valve for leaks.
For reversed supplies installation the
complete mixing valve must be rotated 180°.
Therefore shut-off handle, temperature
handle, cover ring and stop ring must be
dismounted, rotated 180°and reinstalled.
Shower Hose Connection
1.Close free outlet with plug (K), see
Fig. [10].
2.Remove O-ring seal (L1).
3.Turn outlet nipple (L) 180°and fit O-ring
seal (L1).
4.Thread the outlet nipple with the O-ring
seal into the valve body outlet.
5.Connect flexible shower hose.
Open hot and cold water supply.
Check the pipework and connections to the
thermostat mixing valve for leaks.
For reversed supplies installation the
complete mixing valve must be rotated 180°.
Therefore shut-off handle, temperature
handle, cover ring and stop ring must be
dismounted, rotated 180°and reinstalled.

Adjustment
The temperature of the outflowing water is
factory set to 43 °C. A temperature adjust-
ment is necessary if:
•The maximum water temperature
measured at the outlet varies from
the factory set temperature.
•After any maintenance operation on the
thermostatic cartridge.
For temperature adjustment please
proceed as follows:
1.Turn the shut-off handle counter-clockwise
to fully open position and open water flow.
2.Turn the temperature handle counter-
clockwise to maximum hot water
temperature.
3.Lever out cap (M), see fig. [11].
4.Unscrew screw (N).
5.Pull off temperature handle (O).
6.Check the temperature of the outflowing
water with a thermometer, see Fig. [12].
7.Push on temperature handle and adjust
temperature to 43 °C.
Turn clockwise (to reduce temperature)
or counter-clockwise (to increase tem-
perature).
8.Pull off temperature handle (O) and
reinstall in hot water position as described
in Fig. [11] in reversed direction.
