Prior to installation
Safety notes
Protection against scalding
It is recommended that near points of discharge
with particular sensitivity to the outlet
temperature (hospitals, schools, nursing and retirement
homes) thermostatic devices should be installed which
can limit the water temperature to 43 °C. The product
includes an appropriate temperature end stop. 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.This GROHE fitting can
be used in conjunction with a pressurised storage heater
or an instantaneous heater.
Operation with unpressurised storage heaters
( = displacement water heaters) is not possible.
To ensure correct operation of the fitting, the flow
pressure should be between 1 and 5 bar.
It is recommendable to install a pressure-reducing valve
in the case of higher flow pressures.
In the case of new installations, flush the cold
and hot water lines thoroughly until the water is
completely free of contamination before and after
installation. Otherwise these residues remaining
in the lines may block the fitting and contaminate
the drinking water.
Make sure that you do not damage the fitting
surfaces with the tool during installation. For this
reason, always use toothed pliers.
Installation, Pages 2 + 3
The cold water supply must be connected on the
right, hot water supply on the left.
If you have reversed the fitting connections (hot on right –
cold on left), you can correct this by means of the
thermostatic compact cartridge (47 175) available
as a special accessory, see Page 1.
