Operating Instructions

The Geberit Duofix Shower Siphon is designed for automatic and efficient water drainage from your shower area. No specific user operation is required beyond normal shower use, as the system functions passively to drain water.

• Flow Rate: The siphon provides a flow rate of 0.8 liters per second, ensuring quick and effective water removal.
• Odor Trap: An integrated odor trap with a height of 50 mm prevents unpleasant smells from entering the bathroom from the drainage system.

Maintenance

Regular inspection and cleaning of the siphon are recommended to ensure optimal performance and prevent blockages. The design includes an extractable and inspectable immersion tube for easy access.

Cleaning Procedure:

1. Carefully remove the shower drain cover.
2. Locate and gently extract the inspectable immersion tube from the siphon body.
3. Clean any accumulated debris, hair, or soap residue from the immersion tube and the accessible parts of the trap. A brush and warm soapy water are usually sufficient.
4. Rinse all components thoroughly.
5. Reinsert the immersion tube securely into the siphon body.
6. Replace the shower drain cover.

Caution: Avoid using harsh chemical drain cleaners, as these can damage the internal components and seals of the siphon system.

Troubleshooting

This section addresses common issues you might encounter with your Geberit Duofix Shower Siphon.

Issue: Slow Drainage

• Cause: Blockage in the siphon or drain cover.

Issue: Leaks

• Cause: Improperly seated seals or loose connections.
• Solution: If leaks are detected, immediately cease use of the shower. Inspect all visible connections and ensure all seals are properly seated and tightened. If the issue persists or is not easily identifiable, contact a qualified plumber for professional inspection and repair.
