4. Setup and Installation

Follow these steps for proper installation of your Cornat basin siphon:

1. Preparation: Unpack all components and verify against the parts list in Section 2.1. Ensure the main water supply to the basin is turned off.
2. Attach Plunge Tube: Insert the plunge tube into the basin drain opening. Secure it from below with the provided connection nut and seal, ensuring a watertight fit.
3. Connect Siphon Body: Attach the main odor trap siphon body to the bottom of the plunge tube. Hand-tighten the connection nut.
4. Measure and Cut Outlet Pipe: Hold the outlet pipe in position between the siphon body and the wall drain. Measure the required length and carefully cut the pipe if necessary to ensure a proper fit.
5. Install Wall Rosette: Slide the wall rosette onto the outlet pipe.
6. Final Connections: Connect the outlet pipe to the siphon body and the wall drain using the remaining connection nuts and seals. Ensure all seals are correctly seated.
7. Tighten Connections: Hand-tighten all connection nuts first. Then, use a wrench to gently tighten them further, being careful not to overtighten.
8. Leak Test: Turn on the main water supply and allow water to run into the basin. Carefully inspect all connections for any signs of leaks. If leaks are detected, tighten the respective connection slightly until the leak stops.

5. Operation

The Cornat basin siphon operates by creating a water seal, also known as an odor trap. When water drains from your basin, a small amount remains in the curved section of the siphon body. This standing water acts as a barrier, preventing unpleasant sewer gases from rising through the drain and entering your bathroom. Regular use of the basin ensures the water seal is maintained and refreshed.

6. Maintenance

Regular maintenance helps ensure the longevity and proper function of your siphon:

• Routine Cleaning: The siphon cup can be easily unscrewed from the bottom for manual cleaning. Periodically remove it to clear any accumulated hair, soap scum, or debris that could cause blockages or odors.
• Flushing: Occasionally flush the basin with hot water to help dissolve minor grease or soap build-ups within the pipes.
• Seal Inspection: During cleaning, inspect the seals and gaskets for any signs of wear or damage. Replace them if necessary to prevent leaks.

7. Troubleshooting

Here are solutions to common issues you might encounter:

• Issue: Leaks at Connections
  Solution: Check all connection nuts for tightness. Ensure that all seals and gaskets are correctly seated and are not damaged. If a seal is damaged, it may need replacement.
• Issue: Slow Drainage
  Solution: The siphon or basin drain may be partially blocked. Follow the maintenance steps in Section 6 to clean the siphon cup. Check the basin drain for visible hair or debris.
• Issue: Unpleasant Odors
  Solution: Ensure the siphon cup contains water, which forms the odor seal. If the basin has not been used recently, run water for a few seconds to refill the siphon. If odors persist, clean the siphon cup as per maintenance instructions to remove any odor-causing build-up.
