Safety notes
Protection against scalding
It is recommended that near points of discharge with
particular sensitivity to the outlet temperature
(hospitals, schools, nursing and retirement homes)
thermostatic devices should be installed which can limit the
water temperature to 43 °C. This product is limited at 46 °C.
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 standards
(e. g. EN 806-2) and technical regulations for drinking water
must be observed.
Application
Thermostatic mixers are designed for hot water supplies from
pressurised storage heaters and offer the highest temperature
accuracy when used in this way. With sufficient power output
(from 18 kW or 250 kcal/min), electric or gas instantaneous
heaters are also suitable.
Thermostats cannot be used in connection with unpressurised
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, Calibration.

If static pressure exceeds 5 bar, a pressure reducing valve
must be fitted.
Installation
Flush piping system prior and after installation of fitting
thoroughly (Consider EN 806)!
Required dimensions, see dimensional drawings on fold-out
page I and Fig. [1] on fold-out page II.
Install S-unions and screw-mount the mixer, see fold-out
page II, Fig. [2].
Open cold and hot-water supply and check connections
for water-tightness.
Reversed connection (hot on right - cold on left). Replace
thermostatic compact cartridge, see Replacement Parts,
fold-out page I, Prod. no. 47 175 (1/2").
Adjusting
Temperature adjustment, see fold-out page II, Fig. [3].
Temperature limitation
The safety stop limits the temperature range to 38 °C. The 38 °C
limit can be overridden by pressing the button, see Fig. [4].
Installation of the shower rail, see fold-out page II, Figs. [5]
to [9].
When installing e.g. on plasterboard walls (not solid walls) it
must be assured that an appropriate reinforcement is in place
to ensure sufficient strength.
Installation of the head shower, see fold-out page III, Fig. [10].
Shut-off handle operation, see Fig. [11].
Prevention of frost damage
When the domestic water system is drained, thermostats 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.
Maintenance
Inspect and clean all parts, replace if necessary and lubricate
with special grease.
Shut off the hot and cold water supply.
Non-return valve, see fold-out page III, Fig. [12].

The function of the SpeedClean nozzles is guaranteed for a
60 °C
period of five years.
Thanks to the SpeedClean nozzles, which must be regularly
38 °C
cleaned, limescale deposits on the rose can be removed by
simply rubbing with the fingers.
