It is generally recommended that the temperature of shower-
systems should not exceed 38 °C in nurseries and specific
areas of care centres. Use Grohtherm Special thermostats
with special handle to facilitate thermal disinfection and
appropriate safety end stop. Applicable standards (e. g. EN
806-2) and technical regulations for drinking water must be
observed.
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 III, 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 III, Prod. no.: 47 175 (1/2”).
Adjusting
Temperature adjustment, see fold-out page I Fig. [2].
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 (R1) in temperature control handle (R),
see fig. [3]. Handle with preassembled temperature end stop,
ref. no.: 47 981 (see Replacement parts, fold-out page I).
Adjusting the economy stop, see fold-out page II Fig. [5].
If a higher flow rate is desired, the stop can be overridden by
pressing the button, fold-out page II Fig. [6].
Shut-off handle and diverter operation, see fold-out
page II, Fig. [6] .
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 II, Fig. [7].
• Remove connection nipple by turning clockwise (left-hand
thread) using a allen key.
Install in reverse order.
Thermostatic compact cartridge, see fold-out page II,
Fig. [8].
Install in reverse order.
Readjustment is necessary after every maintenance operation
on the thermostatic compact cartridge (see Adjusting).
Ceramic headpart, see fold-out page II, Fig. [5] and [9].
Install in reverse order.
Unscrew and clean
mousseur, see fold-out page III.
Shower, see fold-out page II, Fig. [10].
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 III ( * = special
accessories).

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 robinetteries thermostatiques sont conçues 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), des chauffe-eau instantanés électriques ou
au gaz conviennent également. Les thermostats ne peuvent
pas être utilisés avec des accumulateurs sans pression
(chauffe-eau à écoulement libre). Tous les thermostats sont
réglés en usine sur une pression dynamique de 3 bars.
