unctioning Principle
his Avensys mix ing valve is a thermostatic
ixer with wax cartridge. Turning the shutff lever in a counter-clockwise direction
pens the water flow. Turning the temerature cross handle in a counter-clockwise
irection sets the temperature from cold to
ot.
his product is supplied with connectors to fit
15mm pipework. Connection should be hot
eft, cold right as viewed from the operating
osition. The product is preassembled.
lumbing Systems
his thermostatic mixing valve is sui t able f or
nstallation with:
x Gravity-fed plumbing systems with an
open vented hot water cylinder
x Cold water storage cistern
x Mains pressure unvented and instantan-
eous thermal hot water storage systems
x Multi-point gas water heaters
x Combination boilers with a modulating hot
water output
upply Pipework
nsure the supply pipework is thoroughly
lushed before installing the mixing valve.
ROHE recommends installing isolating
alves upstream of the mixing valve for
ervicing purposes.
Specification
x Exposed thermostatic shower mixing
valve, concealed or exposed supplies
x Flow pressure
- Low pressure 0.1 - 1 ba
- High pressure 1 - 10 ba
x Avoid major pressure differences betwee
hot and cold water supply:
For different supply pressures use
enclosed flow limiters, see chapter
“Exposed Installation” on page 7.
x Max. operating pressure 10 ba
x Max. test pressure 16 ba
x Mixed water flow rate without downstream
resistance:
Pressure 0.1 0.2 0.3 0.4 0.5 0.6 bar
Flow rate 5 7.2 9.2 10.6 11.9 13.0 l/min
x Temperature
- Max. (hot water inlet) 80 q
- Recommended (for economy) 60 q
- Maximum temperature is reached when
the temperature cross handle is rotated
270q in a counter-clockwise direction.
x Water connection cold - R

ew Water Regulations
his GROHE-product should be installed to
omply with the New Water Regulations
overing backflow prevention. It must also
