Practical Information

Versatile – a separate stop valve allows the side showers and the overhead shower to be used at the same time.

Installation information:
Equipped with the latest GROHE technology, the GROHE Rapido T concealed thermostat provides a flow rate of over 50 litres per minute at a pressure of 3 bar. This guarantees an optimum supply of water to the side showers. When dimensioning the drain, make sure that the maximum amount of water produced can run off safely.

Operating this shower with an instantaneous water heater is not recommended. The hot water storage tank should be sufficiently large. When the overhead shower and the side showers are used at the same time, up to 280 litres of hot/cold water are needed in 10 minutes.
To prevent drinking water from being sucked back into the pipe network (see EN 1717), an approved safety device must be fitted when installing a hand shower or a Talentofill filling valve in combination with a bathtub. Such a device is available in the GROHE accessories range – product number 29 007 000.

Please observe the recommended installation height of the overhead shower.
