These components are essential for maintaining the hygiene of your Kinetico water filtration system.
4. Sanitization Procedure
Follow these steps to sanitize your Kinetico KRO+, A200, or K2 system:
4.1. Preparation
- Gather all necessary materials: Kinetico Sanitization Kit (Part 9392B), new operational filter cartridges (if replacing), a clean bucket, and towels.
- Locate the cold water supply valve to your Kinetico system and turn it off completely.
- Open the filtered water faucet (dispensing from your Kinetico system) to relieve system pressure and drain any remaining water. Allow water to flow until it stops.
- Close the filtered water faucet.
- Carefully remove the existing operational filter cartridges from the system. Refer to your system's specific manual for cartridge removal instructions. Dispose of the used cartridges properly.
4.2. Sanitization Cartridge Installation
- Inspect the empty filter housings for any visible debris or sediment. Clean the housings if necessary.
- Unpack the three Kinetico Sanitation Cartridges (Part 9391A).
- Insert the sanitation cartridges into the appropriate filter housings. Ensure they are fully seated and aligned correctly.
- Securely close and tighten the filter housings.
- Note: The 5ml dropper (Part 9393) may be used for adding a specific sanitizing solution (not included) to the system before or during this step. Please consult the detailed instructions provided within your physical kit for its precise application.
4.3. System Flushing and Contact Time
- Slowly turn on the cold water supply valve to the Kinetico system.
- Check all connections for leaks. Address any leaks immediately.
- Open the filtered water faucet and allow water to flow for 5-10 minutes. This flushes the system with the sanitizing agent released from the cartridges.
- Close the filtered water faucet.
- Allow the sanitizing solution to remain in the system for a minimum of 30 minutes. For systems that have been unused for extended periods or are heavily contaminated, a longer contact time (e.g., several hours) may be beneficial.
4.4. Final Flushing and Operational Filter Installation
- After the contact time, open the filtered water faucet and allow water to flow for 10-15 minutes to thoroughly flush the sanitizing solution from the system.
- Close the filtered water faucet.
- Turn off the cold water supply valve to the Kinetico system.
- Open the filtered water faucet again to relieve any remaining pressure.
- Carefully remove and dispose of the sanitation cartridges.
- Install your new operational filter cartridges according to their specific instructions. Ensure they are properly seated and the housings are securely tightened.
- Slowly turn on the cold water supply valve.
- Check for leaks at all connections.
- Open the filtered water faucet and allow water to flow for 5-10 minutes to flush the new operational filters and remove any trapped air.
- The system is now sanitized and ready for normal operation.
5. Maintenance Schedule
It is recommended to sanitize your Kinetico KRO+, A200, or K2 system with the Kinetico Sanitization Kit (Part 9392B) every time you change your operational filter cartridges. This typically occurs every 6 to 12 months, depending on water quality and usage. Regular sanitization helps prevent bacterial growth and ensures the continued delivery of clean, fresh-tasting water.
6. Troubleshooting
- No Water Flow After Sanitization: Ensure the cold water supply valve is fully open. Check that all filter housings are securely tightened and cartridges are correctly installed.
- Unusual Taste or Odor After Sanitization: This may indicate residual sanitizing solution. Continue flushing the system by running water through the filtered water faucet for an extended period (e.g., an additional 15-30 minutes) until the taste or odor dissipates.
- Leaks: Turn off the water supply immediately. Check all connections and O-rings for proper seating and tightness. Replace any damaged O-rings if necessary.
