3. Setup and Installation
The Ibergrif Shower Mixer is designed for wall mounting. Follow these steps carefully for proper installation.
- Preparation: Turn off the main water supply. Clear the installation area. Ensure the existing pipe connections are clean and free of debris.
- Install Eccentric S-Connections: Screw the eccentric S-connections into the wall water outlets. Adjust them until the distance between their centers is 150 mm (standard spacing) and they are level. The adjustable range is ± 10 mm.
- Attach Wall Escutcheons: Place the decorative wall escutcheons over the eccentric S-connections.
- Mount the Mixer: Place the gaskets into the nuts of the shower mixer. Carefully align the mixer with the eccentric S-connections and tighten the nuts. Use a wrench, but do not overtighten to avoid damaging the connections.
- Install Shower Holder: Choose a suitable height for the shower holder on the wall. Mark the drilling points, drill holes, insert wall plugs, and secure the holder with screws.
- Connect Hand Shower and Hose: Connect one end of the 1.5m shower hose to the outlet on the mixer and the other end to the hand shower. Ensure all connections are hand-tightened, then use a wrench for a final snug fit.
After installation, slowly turn on the main water supply and check for any leaks. If leaks occur, tighten the connections slightly more.

4. Operating Instructions
Your Ibergrif Shower Mixer is designed for simple and intuitive operation.
- Water Flow Control: The single-lever handle controls the water flow. Lift the handle upwards to increase flow and push it downwards to decrease flow. Push it all the way down to turn off the water.
- Temperature Control: Move the single-lever handle horizontally to adjust the water temperature.
- Move the handle to the left for hot water.
- Move the handle to the right for cold water.
- Diverter (if applicable): If your model includes a diverter, typically a small knob or button on the mixer body, pull or turn it to switch water flow between the main faucet spout (if present) and the hand shower.
- Hand Shower Use: Remove the hand shower from its holder. Press the button or lever on the hand shower (if present) to adjust spray patterns.

5. Maintenance
Regular cleaning and maintenance will ensure the longevity and optimal performance of your Ibergrif Shower Mixer.
- Cleaning the Surface: Clean the surface regularly with a soft cloth and mild soap or a non-abrasive cleaner specifically designed for bathroom fixtures. Avoid using abrasive sponges, harsh chemicals, or acidic cleaners, as these can damage the coated finish. Rinse thoroughly with clean water and dry with a soft cloth to prevent water spots.
- Cleaning the Hand Shower Nozzles: Over time, mineral deposits can build up in the hand shower nozzles. To clean, gently rub the rubber nozzles with your finger or a soft brush to dislodge any deposits. For stubborn buildup, soak the hand shower head in a solution of equal parts white vinegar and water for a few hours, then rinse thoroughly.
- Checking for Leaks: Periodically inspect all connections for any signs of leaks. If a leak is detected, gently tighten the connection. If the leak persists, the gasket may need to be replaced.
- Cartridge Maintenance: The high-quality ceramic cartridge is designed for durability and leak-free operation. In case of persistent drips or difficulty in controlling temperature/flow, the cartridge may need inspection or replacement by a qualified professional.

6. Troubleshooting
This section addresses common issues you might encounter with your shower mixer.
| Problem | Possible Cause | Solution |
