4. Setup and Installation

Follow these steps carefully to replace the O-rings in your KWC Z.535.950 Luna sliding mechanism.

1. Turn Off Water Supply: Locate the water shut-off valves for your faucet (usually under the sink) and turn them off completely. Open the faucet to drain any remaining water pressure.
2. Disassemble the Faucet/Mechanism: Carefully disassemble the KWC Luna sliding mechanism according to the specific instructions for your faucet model. This typically involves removing handles, decorative caps, and securing nuts or screws to access the internal components where the O-rings are located. Refer to your faucet's original manual if available.
3. Remove Old O-Rings: Using a small pick or screwdriver, carefully remove the old, worn, or damaged O-rings from their grooves. Note their original positions and sizes to ensure correct replacement.
4. Clean Grooves: Thoroughly clean the O-ring grooves and surrounding areas of any debris, mineral deposits, or old lubricant. A soft brush and mild cleaner can be used, followed by rinsing and drying.
5. Lubricate New O-Rings: Apply a thin, even coat of silicone grease or plumber's lubricant (if included or purchased separately) to each new O-ring. This lubrication aids in installation and helps create a better seal.
6. Install New O-Rings: Carefully place the new, lubricated O-rings into their respective grooves. Ensure they are seated properly and not twisted or pinched.
7. Reassemble the Mechanism: Reassemble the faucet's sliding mechanism in reverse order of disassembly. Ensure all parts are correctly aligned and secured. Do not overtighten.
8. Restore Water Supply and Test: Slowly turn the water shut-off valves back on. Check for any leaks around the newly installed O-rings and connections. Operate the faucet to ensure smooth sliding action and proper water flow.

5. Function and Post-Installation Check

After installation, perform the following checks to ensure proper function:

• Leak Detection: Visually inspect all connections and the sliding mechanism area for any signs of water leakage. Run the faucet for a few minutes and check again.
• Smooth Operation: Test the sliding action of the KWC Luna mechanism. It should move smoothly and without excessive resistance.
• Water Flow: Confirm that water flows freely and that there are no unexpected changes in water pressure or temperature control.

6. Maintenance

Regular maintenance can extend the life of your O-rings and prevent future issues.

• Periodic Inspection: Periodically check the faucet for any signs of leaks or stiffness in the sliding mechanism.
• Lubrication: If the sliding action becomes stiff over time, the O-rings may require re-lubrication. Follow the disassembly steps in Section 4 to access and re-lubricate the O-rings.
• Replacement: O-rings are wear-and-tear components. Replace them as needed if leaks persist or if the material shows signs of degradation (cracking, hardening).

7. Troubleshooting

If you encounter issues after installing the O-ring kit, refer to the following common problems and solutions:

• Leakage After Installation:
  • Ensure all O-rings are correctly seated in their grooves and not twisted or pinched.
  • Verify that all connections are tightened appropriately (not overtightened).
  • Check for any nicks or damage on the new O-rings that might have occurred during installation.
  • Confirm that the correct size and type of O-rings were used for your specific KWC Z.535.950 Luna model.
• Stiff or Difficult Sliding Mechanism:
  • Ensure O-rings were adequately lubricated with silicone grease or plumber's lubricant.
  • Check for any misalignment of internal components during reassembly.
  • Verify that no debris or foreign objects are obstructing the sliding path.
