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.

Specifications

• Minimum flow pressure:

If static pressure exceeds 72.5 psi, 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 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 100 °F.
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 100 °F.
The 100 °F limit can be overridden by pressing the button (E),
see Fig. [3].
Shut-off handle (B) operation, see Fig. [3].

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
5. Push escutcheon (J) onto bracket (K) and insert pipe (F) into
6. Push bracket (K) onto backplate (G), align, and fasten with
7. Push the escutcheon (J) against the wall.
8. Push the shower arm (L) onto the pipe connection from
7.25 psi

Prevention of frost damage
approx. 8 L/min or 2.1 gpm When the domestic water system is drained, thermostats must
176 °F be drained separately, since non-return valves are installed in
the hot and cold water connections. For this purpose, the
140 °F mixer must be removed from the wall.

Maintenance
Inspect and clean all parts, replace if necessary and lubricate
with special grease.

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.
