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. 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 standards (e. g. EN 806-2) and technical
regulations for drinking water must be observed.
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).

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)!
Wall installation
1. Install S-unions and attach the sleeve together with the
escutcheon, see fold-out page I, Fig. [1].
2. Screw-mount the mixer and test the connections for
watertightness.
3. Push the sleeve with escutcheon onto the union nut.
4. Screw the escutcheon flush against the wall.

5. Install rack, see Fig. [2].
Pillar mounting
Fit pillar unions and screw-mount the mixer, see Fig. [3].
The projection can be increased by 30mm with an extension,

Reversed connection (hot on right - cold on left).
Replace thermostatic compact cartridge (A), see Replacement
parts, fold-out page II, Prod. no.: 47 175 (1/2").
When using this thermostatic compact cartridge, the Cool
Touch function is no longer available.
Adjusting
Temperature adjustment, see Figs. [4] and [5].
1. Open the shut-off valve and check the temperature of the
water with a thermometer, see Fig. [4].
2. Lever out cap (B), see Fig. [5].
3. Remove screw (C).
4. Detach temperature control handle (D).
5. Turn regulating nut (E) until the water temperature has
reached 38 °C.
6. Install temperature control handle (D) so that button (F) is at
the top, see Fig. [4].
7. Screw in screw (C), see Fig. [5].
8. Refit cap (B).
Temperature limitation
The safety stop limits the temperature range to 38 °C. The 38 °C
limit can be overridden by pressing the button (F).
Temperature end stop
If the temperature end stop is at 43 °C, insert accompanying
temperature limiter (D1) in temperature selection handle (D),
see Fig. [6]. Handle with preassembled temperature end stop,
Prod. no.: 47 917 (see Replacement parts, fold-out page II).

Prevention of frost damage
10 bar
When the domestic water system is drained, thermostats must
1 - 5 bar
be drained separately, since non-return valves are installed in
16 bar
the hot and cold water connections. For this purpose, the
approx. 20 l/min
mixer must be removed from the wall.

Maintenance
38 °C
Inspect and clean all parts, replace if necessary and lubricate
with special grease.
Shut off hot and cold water supplies.
