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:
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
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.

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.
