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).

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. [3].
2. Remove the temperature control handle (C), see Fig. [4].
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. [3].
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].
Shut-off handle (B) and diverter (G) operation, see fold-out
page III, Fig. [10] and [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. 8,2 l/min
Maintenance
Inspect and clean all parts, replace if necessary and lubricate
approx. 8,2 l/min
with special grease.
approx. 12,5 l/min
Shut off the hot and cold water supply.
approx. 12,5 l/min
approx. 20,0 l/min I. Non-return valve (H) or (J), see fold-out page III, Fig. [12].
70 °C
• Remove connection nipple (K) by turning clockwise (left-hand
thread) using a 12mm allen key.
60 °C
Install in reverse order.
II. Thermostatic compact cartridge (A), see fold-out
38 °C
page III, Fig. [13].
Install in reverse order.
Observe the correct installation position of the
right
thermostatic compact cartridge (A), see details, Fig. [13].

Readjustment is necessary after every maintenance
= 5 l/min
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, see fold-out page III, Fig. [16].
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).
