Setup and Installation
1. Pre-Installation
- Ensure the main water supply to the installation area is turned off.
- Flush the water pipes thoroughly to remove any debris.
- Gather necessary tools: adjustable wrench, PTFE tape, spirit level.
2. Mounting the S-unions
The S-unions connect the mixer to your wall water outlets. They allow for adjustment to achieve the correct spacing and level for the mixer.
- Apply PTFE tape to the threaded ends of the S-unions that connect to the wall outlets.
- Screw the S-unions into the hot and cold water outlets in the wall.
- Adjust the S-unions until the distance between their centers is 150mm (±15mm) and they are level. The outlets should protrude approximately 59mm from the wall.
- Ensure the S-unions are tightened securely, but do not overtighten.

- Insert the sealing washers into the nuts of the shower mixer.
- Carefully align the mixer with the S-unions and hand-tighten the nuts.
- Using an adjustable wrench, tighten the nuts securely. Avoid overtightening to prevent damage.
- Turn on the main water supply and check for leaks at all connections.

Operating Instructions
The GROHE Eurosmart Cosmopolitan OHM Shower Mixer features a single lever for controlling both water flow and temperature.

- Water Temperature: Move the lever to the left for hot water and to the right for cold water. Adjust the position between left and right to achieve the desired temperature.
This mixer is designed for high-pressure systems, ensuring a consistent and powerful shower experience with a minimum recommended pressure of 1.0 bar.
Maintenance
To maintain the polished chrome finish and ensure optimal performance of your GROHE shower mixer, follow these guidelines:
- Cleaning: Clean the mixer regularly with a soft cloth and mild soap or a non-abrasive liquid cleaner specifically designed for bathroom fixtures. Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
- Avoid: Do not use abrasive cleaners, scouring pads, solvents, or acid-based cleaners, as these can damage the scratch-resistant finish.
- Aerator Maintenance: Periodically unscrew and clean the aerator (if applicable) to remove any mineral deposits that may affect water flow.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Low water flow | Clogged aerator; low water pressure; partially closed stopcock. | Clean or replace aerator; ensure water pressure meets minimum 1.0 bar requirement; check that stopcocks are fully open. |
