Technical Data
Functioning Principle
Specification
This Avensys mixing valve is a thermostatic
mixer with wax cartridge. Turning the shutoff handle in a counter-clockwise direction
opens the water flow. Turning the temperature handle in a counter-clockwise
direction sets the temperature from cold to
hot.
• Exposed thermostatic shower mixing
valve, concealed or exposed supplies
• Flow pressure
- Low pressure
- High pressure
0.1 - 1 bar
1 - 10 bar
• Avoid major pressure differences between
hot and cold water supply:
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.
For different supply pressures use
enclosed flow limiters, see chapter
“Exposed Installation” on page 7.
• Max. operating pressure
10 bar
Plumbing Systems
• Max. test pressure
16 bar
This thermostatic mixing valve is suitable for
installation with:
• Mixed water flow rate without downstream
resistance:
• Gravity-fed plumbing systems with an
open vented hot water cylinder
• Cold water storage cistern
• Mains pressure unvented and instantaneous thermal hot water storage systems
• Multi-point gas water heaters
• Combination boilers with a modulating hot
water output

• Temperature
- Max. (hot water inlet)
80 °C
- Recommended (for economy)
60 °C
- Maximum temperature is reached when
the temperature handle is rotated 270°
in a counter-clockwise direction.
Supply Pipework
• Water connection
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.

Installation
Exposed Installation
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 compression rings (A2), see Fig. [2].
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.

Adjustment
6.Check the temperature of the outflowing
water with a thermometer, see Fig. [12].
The temperature of the outflowing water is
factory set to 41 °C. A temperature adjustment is necessary if:
12
• 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 lever handle counter-clockwise to
fully open position and open water flow.
2.Lever out cap (M), see fig. [11].
41 °C

7. With a small screw driver adjust
tempera-ture to 41 °C.
Turn clockwise (to reduce temperature)
or counter-clockwise (to increase temperature).

position as described in Fig. [11] in
reversed direction.
