Setup and Installation
Important: Installation should be performed by a qualified professional plumber in accordance with local plumbing and building codes. Before beginning installation, ensure all necessary components are present and undamaged. Refer to the detailed installation guide included with your product for specific instructions and diagrams.
General Installation Steps:
- Preparation: Turn off the main water supply to the installation area. Clear the work area and ensure you have all required tools.
- Rough-in Valve Installation: Install the GrohSafe 3.0 Pressure Balance Rough Valve (35 117) within the wall. Ensure proper depth and alignment according to the provided template and local code requirements.
- Piping Connections: Connect the hot and cold water supply lines to the designated inlets on the rough-in valve. Connect the outlets to the shower arm and hand shower wall union. Ensure all connections are secure and watertight.
- Shower Arm Installation: Secure the Rainshower 15-inch Shower Arm (26 632) to the wall outlet, ensuring it is properly sealed and angled.
- Shower Head Attachment: Attach the Rainshower 310 Mono Shower Head (26 570) to the shower arm. Hand-tighten, then use a wrench for a final quarter turn, being careful not to overtighten.
- Valve Trim Installation: Install the Eurocube Pressure Balance Valve Trim (29 423) over the rough-in valve. Follow the instructions to align the handle and diverter correctly.
- Hand Shower Components: Install the wall union for the hand shower hose. Connect the shower hose to the wall union and then to the slim hand shower.
- Testing: Once all components are installed, slowly turn on the main water supply. Check all connections for leaks. Test the functionality of the shower head, hand shower, and the diverter to ensure proper operation and temperature control.
Operating Instructions
The GROHE Eurocube Pressure Balance Rainshower Set is designed for simple and intuitive operation.
- Temperature Control: Rotate the main handle to adjust the water temperature. Turning it counter-clockwise typically increases hot water, while clockwise decreases it. The pressure balance valve maintains a consistent temperature, preventing sudden changes due to water pressure fluctuations in your home.
- Water Flow Control: The main handle also controls the water flow. Rotate it to increase or decrease the flow rate to your desired intensity.
- Diverter Function: The 2-way diverter on the valve trim allows you to switch between the main rain shower head and the hand shower. Rotate the diverter knob to select your desired water outlet.
- Hand Shower Use: The slim, single-spray SPA stick hand shower provides a focused spray. Position it as needed for targeted rinsing or cleaning.
Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your GROHE shower set.
Cleaning the Finish:
Use only a soft cloth and a mild, non-abrasive cleaning agent. Avoid cleaners containing alcohol, ammonia, bleach, or abrasive particles, as these can damage the Brushed Nickel finish. Wipe surfaces gently and rinse thoroughly with clean water, then dry with a soft cloth to prevent water spots.
Cleaning the Shower Head Nozzles:
The GROHE Rainshower head features SpeedClean anti-lime system nozzles. To remove limescale buildup, simply wipe the silicone nozzles with your finger or a cloth. This flexible material allows for easy removal of mineral deposits.
General Care:
Periodically check all connections for leaks. If a leak is detected, gently tighten the connection or replace the washer or O-ring as necessary. Avoid using excessive force when operating handles or diverters.
Troubleshooting
This section addresses common issues you might encounter with your shower set and provides potential solutions.

- Solution: Clean the SpeedClean nozzles on the shower head by wiping them. Disassemble and clean the hand shower aerator if necessary.
- Possible Cause: Partially closed shut-off valves in your plumbing system.
- Solution: Ensure the shut-off valves supplying water to the shower are fully open.
Issue: Inconsistent Water Temperature
