3. Setup and Installation
Before beginning installation, ensure your water purifier is turned off and disconnected from the power supply. Refer to your specific Coway water purifier's manual for detailed instructions on accessing and replacing filters.
- Prepare the Area: Place a towel or tray under the filter housing to catch any spilled water.
- Turn Off Water Supply: Locate and turn off the water supply valve to your water purifier.
- Depressurize System: Open the dispenser faucet on your water purifier to release any remaining pressure.
- Remove Old Filters: Carefully remove the old filters from their housings. Note the orientation of each filter (Sediment, RO Membrane, Post Carbon) for correct replacement.
- Install New Filters: Insert the new FILTER TECH replacement filters into their respective housings. Ensure a snug fit and correct orientation. The image above shows the general appearance of each filter type.
- Secure Connections: Double-check all connections to ensure they are tight and leak-free.
- Restore Water Supply: Slowly turn on the water supply valve to your water purifier.
- Check for Leaks: Inspect all connections for any signs of leaks. If leaks are detected, turn off the water supply and re-tighten connections.
4. Operating Instructions: Initial Flushing
After installing new filters, it is crucial to flush the system to remove air and any carbon powder (charcoal powder) that may be present from the manufacturing process. This step ensures optimal water quality and filter performance.
- Flushing Procedure: For each newly installed filter, allow water to flow through the system for approximately 2 minutes, or until about 4 liters of water have passed through.
- Repeat for Each Filter: If filters are replaced individually or in stages, repeat this flushing process for each new filter installed.
- Discard Initial Water: Do not consume the water from the initial flushing. Discard it.
- Ready for Use: After flushing, the water purifier is ready for normal operation.
Caution: Before drinking the water, please make sure to flush water thoroughly to ensure that the air is discharged and carbon powder is removed.
5. Maintenance and Filter Replacement
Regular maintenance, primarily timely filter replacement, is essential for maintaining water quality and the efficiency of your water purifier. The replacement frequency may vary based on water quality and usage.
- Filter Lifespan: Refer to your Coway water purifier's manual or the filter manufacturer's recommendations for the specific lifespan of each filter type (Sediment, RO Membrane, Post Carbon).
- Signs of Replacement: Replace filters if you notice a decrease in water flow, a change in water taste or odor, or if your purifier's indicator light signals a filter change.
- Replacement Procedure: Follow the "Setup and Installation" steps outlined in Section 3 for replacing old filters with new ones. Always remember to flush the new filters as described in Section 4.
6. Troubleshooting
