5. Operating Instructions

The Grohtherm 1000 features two handles for controlling water flow and temperature.

5.1 Temperature Control

• The left handle controls the water temperature.
• Rotate the handle to adjust the temperature. The default safety stop is set at 100°F (38°C).
• To exceed 100°F (38°C), press the SafeStop button on the handle and continue rotating.
• The GROHE TurboStat technology ensures a constant water temperature, even with fluctuations in water pressure.

5.2 Flow Control

• The right handle controls the water flow rate.
• Rotate the handle to increase or decrease the water volume.
• The EcoButton allows for a reduced flow rate for water saving. Press the EcoButton to bypass this stop and achieve maximum flow.

6. Maintenance

6.1 Cleaning the Finish

• Clean the GROHE StarLight chrome finish with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for chrome fixtures.
• Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
• Avoid using abrasive sponges, scouring pads, or cleaners containing alcohol, ammonia, or phosphoric acid, as these can damage the finish.

6.2 Filter Maintenance

• The valve includes dirt strainers to protect the thermostatic cartridge. If water flow decreases or temperature regulation becomes inconsistent, these strainers may need cleaning.
• Consult a qualified plumber for cleaning or replacing internal components. Always turn off the water supply before any internal maintenance.
