The installation guide must be read
carefully before commissioning and
kept for future reference. Noncompliance
or improper use releases
the manufacturer from liability.
Safety notes - protection against scalding
It is recommended that near points of discharge
with particular sensitivity to the outlet
temperature (hospitals, schooles, nursing and
retirement homes) thermostatic devices should
be installed which can limit the water
temperature to 43°C. The product includes an
appropriate temperature end stop. It is
generally recommended that the temperature of
shower-systems should not exceed 38°C in
nurseries and specific areas of care centres.
Use Grohtherm Special thermostats with
special handle to facilitate thermal disinfection
and appropriate safety end stop. Applicable
standard (eg.g EN 806-2) and technical
regulations for drinking water must be
observed.
Before installation, waters should be rinse
through the pipe to remove any residue.
Damage on the product can be avoided.
Installation must be performed in compliance
with applicable local construction and plumbing
regulations. If in doubt, contact GROHE or an
expert. The safety device within the fitting
protects the drinking water quality and must not
A
be modified and should only be replaced by an
expert.
Before changing the fitting switch off main shut-
off valve.
B
The installation of S-unions can be complex. To
avoid any accidental damages on your piping
system, we recommend to do this by a qualified
expert. Furthermore, if S-unions are slanted
from your previous thermostat, please contact a
C
qualified expert.
CAUTION!
Do not overtighten the screw connections, even
with the seal inserted, to avoid damage.
D
Thermostats must be installed with the
adjustment in temperature at 38°C to meet the
necessary safety-related requirements.
E
Temperature end stop
If the termperature end stop is at 43°C, insert
accompanying temperature limiter in
temperature selection handle.
F
Check at regular intervals to make
sure that the installation is not
leaking.
G
If temperature connections are reversed (hot on
right - cold on left) the thermostatic compact
catrridge needs to be replaced. A qualified
expert is recommended for this.

Specifications
Safety stop 38 °C
Hot water temperature at supply connection
min. 2 °C higher than mixed water temperature
Minimum flow rate = 5 l/min
If static pressure exceeds 5 bar, a pressure
reducing valve
must be fitted.
Application
Thermostat mixers are designed for hot water
supply via pressurised storage heaters and,
utilised in this way, provide the best
temperature accuracy. With sufficient power
output (from 18 kW or 250 kcal/min), electric or
gas instantaneous heaters are also suitable.
Thermostats cannot be used in conjunction with
non-pressurised storage heaters (displacement
water heaters).
All thermostats are adjusted in the factory at a
flow pressure of 3 bar on both sides.
Should temperature deviations occur on
account of special installation conditions, the
thermostat must be adapted to local conditions
(see Adjusting).
Prevention of frost damage
When the domestic water system is drained,
thermostat mixers must be drained separately,
since non-return valves are installed in the hot
and cold water connections. For this purpose,
the mixer must be removed from the wall.
