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.

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 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. 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].
Shut-off handle (B) operation, see Fig. [3].
Hand shower = Turn the shut-off handle
Head shower
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.
1. Insert pipe (F) in the mixer body, see Fig. [5].
2. Align pipe (F) and mark position of bores.
3. Drill holes and insert plugs, see Fig. [6].
4. Pull O-ring (G1) onto backplate (G) and fasten with
screws (H) using seal (I), see Fig. [7].
5. Push escutcheon (J) onto bracket (K) and insert pipe (F) into
mixer body, see Fig. [8].
6. Push bracket (K) onto backplate (G), align, and fasten with
set screw (G1).
7. Push the escutcheon (J) against the wall.
0.5 bar
8. Push the shower arm (L) onto the pipe connection from
10 bar
above and secure with set screw (L1), see Fig. [9].
1 - 5 bar
9. Attach hand shower (M) to hose (N) using the supplied
16 bar
filter (M1) and connect to mixer.

Installation of the head shower, see fold-out page III,
approx. 14 l/min

approx. 12 l/min
80 °C Prevention of frost damage
When the domestic water system is drained, thermostats must
be drained separately, since non-return valves are installed in
60 °C
38 °C the hot and cold water connections. For this purpose, the
mixer must be removed from the wall.
Maintenance
right
Inspect and clean all parts, replace if necessary and lubricate
left
with special grease.
= 5 l/min
Shut off the hot and cold water supply.
I. Non-return valve (Q) or (R), see fold-out page III, Fig. [11].
• Remove connection nipple (P) by turning clockwise (left-hand
thread) using a 12mm allen key.
Install in reverse order.
II. Thermostatic compact cartridge (A), see fold-out
page III, Fig. [12].
• Remove O-ring (S).
• Loosen screw ring (T) using a 34mm tool.
• If necessary, lever out thermostatic compact cartridge (A)
via recess (A1).
• Remove screw ring (T).
Install in reverse order.
Observe the correct installation position of the
thermostatic compact cartridge (A), see details, Fig. [12].
Readjustment is necessary after every maintenance
operation on the thermostatic compact cartridge
(see Adjusting).
III. Aquadimmer (U), see fold-out page III, Figs. [13] and [14].
Install in reverse order.
Observe correct installation position of individual
components, see details.
IV. Shower, see fold-out page III, Fig. [15].
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).
