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).
Specifications
Minimum flow pressure without
downstream resistances 0.5 bar
Minimum flow pressure with
downstream resistances 1 bar
Max. operating pressure 10 bar
Recommended flow pressure 1 - 5 bar
Test pressure 16 bar
Flow rate at 3 bar flow pressure
Bath approx. 20 l/min
Shower approx. 25 l/min
Max. water temperature at hot water supply 70 °C
Recommended max. flow temperature (energy saving) 60 °C
Thermal disinfection possible
Safety stop 38 °C
Hot water temperature at supply connection min. 2 °C higher
than mixed water temperature
Cold water connection right
Hot water connection left
Minimum flow rate = 5 l/min
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)!
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
When the domestic water system is drained, thermostat
mixers must be drained separately, since non-return valves
are installed in the hot and cold water connections. For this
purpose, the mixer must be removed from the wall.
Maintenance
Inspect and clean all parts, replace if necessary and lubricate
with special valve grease.
Shut off the hot and cold water supply.
Non-return valve, see fold-out page III, Fig. [8].
Remove connection nipple using a 12mm allen key.
Install in reverse order.
Thermostatic compact cartridge, see fold-out page III,
Fig. [9].
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,
Fig. [5] and [11].
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.
Replacement parts, see fold-out page II ( * = special
accessories).
Care
For directions on care, refer to the accompanying Care
Instructions.
