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
- bath
• Max. water temperature at hot water supply:
• Recommended max. flow temperature
(energy economy):
• 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.
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 (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 bath
and measure the temperature of the running water using a
thermometer, see Fig. [4].
2. Remove the temperature control handle (C), see Fig. [3].
3. Turn regulating nut (D) until the water temperature
reaches 38 °C.
4. Fit temperature control handle (C) so that the 38 °C marking
coincides with the marking (C1), see Fig. [4].
Temperature limitation
The safety stop limits the temperature range to 38 °C. The 38 °C
limit can be overridden by pressing the button (E), see Fig. [3].
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 II,
Fig. [9].
Insert seal (F1) and filter (F2) and screw head shower (F) onto
shower arm.
Shut-off handle (B) and diverter (G) operation, see fold-out
page III, Fig. [10] and [11].

When the domestic water system is drained, thermostats must
be drained separately, since non-return valves are installed in
approx. 8,2 l/min
the hot and cold water connections. For this purpose, the
approx. 12,5 l/min
mixer must be removed from the wall.
approx. 20,0 l/min
Maintenance
80 °C
Inspect and clean all parts, replace if necessary and lubricate
with special grease.
60 °C
Shut off the hot and cold water supply.
38 °C

Install in reverse order.
= 5 l/min
II. Thermostatic compact cartridge (A), see fold-out
page III, Fig. [13].
• Remove O-ring (M).
• Loosen screw ring (L) using a 34mm tool.
• If necessary, lever out thermostatic compact cartridge (A)
via recess (A1).
• Remove screw ring (L).
Install in reverse order.
Observe the correct installation position of the
thermostatic compact cartridge (A), see details, Fig. [13].
Readjustment is necessary after every maintenance
operation on the thermostatic compact cartridge
(see Adjusting).
III. Aquadimmer (N), see fold-out page III, Figs. [14] and [15].
Install in reverse order.
Observe correct installation position of individual
components, see details.
IV. Shower
The function of the SpeedClean nozzles is guaranteed for a
period of five years.
Simply rub SpeedClean nozzles in order to remove limescale
deposits from rose.
Replacement parts, see fold-out page I ( * = special
accessories).
