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.

Technical Data

• Minimum flow pressure:
• Max. operating pressure:
• Recommended flow pressure:
• Test pressure:
• Flow rate at 3 bar flow pressure:
- head shower
- hand shower
• Max. water temperature at hot water supply:
• Recommended max. flow temperature
(energy economy):
• Thermal desinfection possible
• Safety stop:
• Hot water temperature at supply connection min. 2 °C higher
than mixed water temperature
• Cold water connection:
• Hot water connection:
• Minimum flow rate:
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.
1. Install S-unions and attach the sleeve together with the
escutcheon, see fold-out page II, Fig. [2].
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.
Reversed connection (hot on right - cold on left). Replace
thermostatic compact cartridge (A), see Replacement Parts,
fold-out page I, Prod. no. 47 175 (1/2").
Adjusting
For temperature adjustment (calibration), see fold-out
page II, Figs. [3] and [4].
1. Open the shut-off handle (B) by turning towards the hand
shower and measure the temperature of the running water
using a thermometer, see Fig. [3].
2. Remove the temperature control handle (C), see Fig. [4].
3. Turn regulating nut (D) until the water temperature
reaches 38 °C.
4. Install temperature control handle (C) so that button (C1)
points towards the front, see 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 (C1), see Fig. [3].
Temperature end stop
If the temperature end stop is at 43 °C, insert accompanying
temperature limiter (C2) in temperature selection handle (C),
see Fig. [5]. Handle with preassembled temperature end stop,
Prod. no.: 47 958 (see Replacement parts, fold-out page I).
Installation of the shower rail, see fold-out page II, Figs. [6]
to [10].
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 II,
Fig. [10].
Shut-off handle (B) operation, see fold-out page III, Fig. [11].
0.5 bar
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
mixer must be removed from the wall.
approx. 12 l/min
approx. 8 l/min
Maintenance
70 °C
Inspect and clean all parts, replace if necessary and lubricate
with special grease.
60 °C
max. 90 °C
Shut off the hot and cold water supply.
38 °C
I. Non-return valve (Q) or (R), see fold-out page III, Fig. [12].
• Remove connection nipple (P) by turning clockwise (left-hand
right
thread) using a 12mm allen key.
left
Install in reverse order.
= 5 l/min
II. Thermostatic compact cartridge (A), see fold-out
page III, Fig. [13].
Install in reverse order.
Observe the correct installation position of the
thermostatic compact cartridge (A), see details.
Readjustment is necessary after every maintenance
operation on the thermostatic compact cartridge
(see Adjusting).
III. Aquadimmer (S), see fold-out page III, Figs. [14] and [15].
Install in reverse order.
Observe correct installation position of individual
components, see details.
IV. Shower, see fold-out page III, Figs. [16] and [17].
Install in reverse order.
The function of the SpeedClean nozzles is guaranteed for a
period of five years.
Thanks to the SpeedClean nozzles, which must be regularly
cleaned, limescale deposits on the rose can be removed by
simply rubbing with the fingers.
Replacement parts, see fold-out page I ( * = special
accessories).
