Application
Thermostat mixers are designed for hot water supply via
pressurised storage heaters and, utilised in this way, provide
the best temperature accuracy. With sufficient power output
(from 18 kW or 250 kcal/min), electric or gas instantaneous
heaters are also suitable.
Thermostats cannot be used in conjunction with
non-pressurised 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).

Installation
Flush piping system prior and after installation of fitting
thoroughly (Consider EN 806)!
Install unions and screw-mount the mixer, see fold-out page I,
Fig. [1].
Refer to the dimensional drawing on fold-out page I.
The projection can be increased by 20mm with an extension,
see Replacement Parts, fold-out page II, Prod. no. 07 130.
Open cold and hot-water supply and check connections
for water-tightness.
Reversed connection (hot on right - cold on left).
Replace thermostatic compact cartridge, see Replacement
parts, fold-out page II, Prod. no.: 47 175 (1/2").
When using this thermostatic compact cartridge, the Cool
Touch function is no longer available.
Adjusting
Temperature adjustment, see fold-out page I Fig. [2].
Temperature limit stop
If the temperature limit stop should be 43 °C, use handel ref.
No. 47 973, 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, see
Fig. [4].
Shower mixer:
Adjusting the economy stop, see fold-out page III Fig. [5].
If a higher flow rate is desired, the stop can be overridden by
pressing the button, fold-out page III Fig. [6].
Bath mixer:
Handle operation, see fold-out page III Fig. [7].
Eco function, by pressing the button the flow rate for the
shower can be increased.
Prevention of frost damage
0.5 bar
When the domestic water system is drained, thermostat
1 bar
mixers must be drained separately, since non-return valves
10 bar are installed in the hot and cold water connections. For this
purpose, the mixer must be removed from the wall.
1 - 5 bar
16 bar
Maintenance
approx. 20 l/min
Inspect and clean all parts, replace if necessary and lubricate
approx. 25 l/min
with special valve grease.
70 °C
Shut off the hot and cold water supply.
Non-return valve, see fold-out page III, Fig. [8].
38 °C
Remove connection nipple using a 12mm allen key.
Install in reverse order.

Readjustment is necessary after every maintenance operation
on the thermostatic compact cartridge (see Adjusting).
Aquadimmer (bath mixer), see fold-out page III, Fig. [10].
Ceramic headpart (shower mixer), see fold-out page III,

Install in reverse order.
Unscrew and clean mousseur (13 952) see fold-out page II.
Shower, see fold-out page III, Fig. [12].
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.
