3. Installation and Setup

Before beginning the installation process, ensure your Coway water purifier is turned off and disconnected from the power supply. Refer to your Coway purifier's specific manual for instructions on accessing the filter compartments.

1. Prepare the Area: Place a towel or tray under the filter area to catch any water spills.
2. Remove Old Filters: Carefully remove the old filters from their respective positions. Note the order and orientation of each filter.
3. Install New Filters: Insert each new FilterTech replacement filter into its corresponding position. Ensure a secure fit. The plastic spanner may be used to tighten filter housings if applicable to your model.
4. Connect Hoses: If any hoses were disconnected, reattach them securely using the L fitting connectors if needed.
5. Flush the System: This is a critical step. After installing new filters, it is essential to flush the system to remove any carbon powder (charcoal powder) from the filter manufacturing process and discharge air.
   • Turn on the water supply to the purifier.
   • Allow water to flow through each newly installed filter for approximately 2 minutes (about 4 liters).
   • Repeat this flushing process for each filter individually if your system allows, or flush the entire system until the water runs clear and free of air bubbles.
6. Check for Leaks: After flushing, carefully inspect all connections for any signs of leaks.
7. Restore Power: Once installation is complete and no leaks are detected, reconnect the power supply to your Coway water purifier.

Caution: Always flush new filters thoroughly before consuming water to ensure optimal performance and safety.

4. Operation

Once the FilterTech replacement filters are correctly installed and flushed, your Coway water purifier will operate as usual, providing filtered water. The filters work continuously to remove impurities and improve water quality.

No special operational steps are required for the filters themselves beyond ensuring they are properly installed and replaced according to the recommended schedule.

5. Maintenance and Filter Replacement

Regular filter replacement is crucial for maintaining the performance and effectiveness of your water purifier. Adhere to the following replacement schedule:

• Sediment Filter (1st Filter): Replace every 3-4 months.
• Pre-Carbon Filter (2nd Filter): Replace every 6-8 months.
• UF Membrane Filter (3rd Filter): Replace every 12-16 months.
• Post-Carbon Filter (4th Filter): Replace every 9-12 months.

Note: Filter lifespan may vary depending on water quality and usage volume. It is recommended to replace filters at or before the suggested intervals.

When replacing filters, always follow the installation steps outlined in Section 3, paying particular attention to the flushing procedure.

6. Troubleshooting

If you encounter issues after installing your FilterTech replacement filters, consider the following common troubleshooting steps:

• Reduced Water Flow:
  • Ensure all filters are correctly seated and tightened.
  • Check for kinks in the water supply lines.
  • Verify that the water supply valve to the purifier is fully open.
  • If filters are old, they may be clogged and require replacement.
• Unusual Taste or Odor:
  • Ensure new filters have been thoroughly flushed as per Section 3. This is crucial for removing manufacturing residues.
  • If the taste/odor persists, check if any filters are past their recommended replacement date.
• Leaks:
  • Turn off the water supply immediately.
  • Inspect all connections and O-rings for proper seating and damage.
  • Ensure filter housings are securely tightened. The included plastic spanner can assist with this.
  • If a leak persists, contact customer support.
