Setup and Installation

Components Checklist:
- FRANKE 112.0551.361 Siphon assembly
- Sealing gaskets (pre-installed or separate)
- Connection nuts
Installation Steps:
- Preparation: Turn off the water supply to the sink. If replacing an old siphon, place a bucket underneath and carefully disconnect the old unit. Clean the sink drain opening and the wall connection point.
- Assemble the Siphon: Connect the horizontal pipe of the siphon to the sink's drain outlet. Ensure all gaskets are correctly seated and tighten the connection nut hand-tight, then use a wrench for a final quarter turn, being careful not to overtighten.
- Connect to Wall Drain: Connect the vertical outlet of the siphon to the wall drain pipe. The wall connection diameter is 40 mm. Adjust the length and angle of the pipes as needed to ensure a proper fit. Secure all connections with appropriate nuts and gaskets.
- Side Connections (Optional): If connecting a dishwasher or washing machine, use the designated side inlet. Ensure a secure, leak-free connection. If not used, ensure the cap is securely in place.
- Leak Test: Once all connections are secure, turn on the water supply and fill the sink. Allow water to drain and carefully inspect all connections for any leaks. Tighten any leaking connections as necessary.
Note: For optimal performance, ensure all connections are clean and free of debris before assembly.
Operating Instructions
The FRANKE 112.0551.361 Siphon operates automatically as water drains from the sink. Its primary function is to create a water seal that prevents sewer gases from entering your home.
- Ensure the sink drain is clear of large debris before draining water.
- The bottle trap design allows for easy access to clear blockages if they occur within the trap itself.
Maintenance
Regular maintenance will ensure the longevity and efficient operation of your FRANKE siphon.
Cleaning the Siphon:
- Disassembly: Place a bucket underneath the siphon. Unscrew the bottom cap of the bottle trap.
- Cleaning: Remove any accumulated debris, food particles, or hair from inside the trap. Rinse the cap and the interior of the trap with warm, soapy water.
- Reassembly: Securely reattach the bottom cap, ensuring the gasket is properly seated to prevent leaks.
- Test: Run water through the sink to check for leaks.
Frequency: It is recommended to clean the siphon every 3-6 months, or more frequently if slow drainage is observed.
General Care:
- Avoid pouring harsh chemicals down the drain, as they can damage the siphon material and gaskets.
- Do not dispose of large food scraps or grease down the sink, as this can lead to blockages.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Slow Drainage | Accumulation of debris in the trap or drain pipe. | Clean the siphon trap as described in the Maintenance section. If the problem persists, the blockage may be further down the drain pipe. |
| Leaking Connections | Loose connection nuts or improperly seated gaskets. | Ensure all connection nuts are tightened securely. Check that gaskets are correctly positioned and not damaged. Replace damaged gaskets if necessary. |
| Unpleasant Odors | Dry trap (water seal evaporated) or debris buildup. | Run water down the sink to refill the trap. Clean the siphon trap to remove any odor-causing debris. Ensure the siphon is correctly installed to maintain the water seal. |
