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.

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, see Replacement Parts,
fold-out page I, Prod. no. 47 175 (1/2”).
Adjusting
Temperature adjustment,
see fold-out page II, 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].
Temperature end stop
If the temperature end stop is at 43 °C, insert accompanying
temperature limiter in temperature selection handle, see Fig. [4].
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 III, Fig. [10].
Shut-off handle operation,
see Fig. [11].
Prevention of frost damage
When the domestic water system is drained, thermostats 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 grease.
Shut off the hot and cold water supply.
Non-return valve,
see fold-out page III, Fig. [12].
Install in reverse order.
Thermostatic compact cartridge,
see fold-out page III,
Fig. [13].
Install in reverse order.
Readjustment is necessary after every maintenance
operation on the thermostatic compact cartridge
(see Adjusting).
Aquadimmer,
see fold-out page III, Fig. [14].
Install in reverse order.
Shower,
see fold-out page III, Fig. [15].
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).
Care
For directions on care, refer to the accompanying Care
Instructions.

Prévention d’échaudage
Pour des points de puisage où la température de
l’eau est particulièrement critique (hôpitaux, écoles,
résidences médicalisées), il est recommandé de
systématiquement utiliser des thermostats pouvant être limités
à 43 °C. Une butée de température permettant la limitation est
incluse avec ce produit. Pour les systèmes de douche dans les
écoles maternelles et dans certaines parties de résidences
médicalisées, il est généralement recommandé de ne pas
dépasser une température de 38 °C. Utilisez ici des
thermostats Grohtherm Special avec poignée spéciale pour
l’aide à la désinfection thermique et la butée finale de sécurité
correspondante. Respectez les normes en vigueur (par ex.
EN 806 2) ainsi que les règlementations techniques pour l’eau
potable.
Domaine d'application
Les mitigeurs thermostatiques sont conçus pour fournir de
l'eau chaude avec des accumulateurs sous pression et
permettent d'obtenir une température de l'eau extrêmement
précise. Si la puissance est suffisante (à partir de 18 kW
ou 250 kcal/min), les chauffe-eau instantanés électriques ou
au gaz conviennent également.
Les thermostats ne sont pas compatibles avec les chauffe-eau
à écoulement libre.
Tous les thermostats sont réglés en usine sur une pression
dynamique de 3 bars.
Si des différences de température devaient apparaître, régler
le thermostat en fonction des conditions locales d'utilisation
(voir Réglage).
Caractéristiques techniques
Pression d’alimentation minimale
0,5 bar
Pression de service maximale
10 bars
Pression dynamique recommandée
1 à 5 bars
