Installation Instructions
These instructions are for replacing an existing in-line filter. If you are installing a new system, refer to your system's specific installation guide.
Before You Begin:
- Ensure you have the correct replacement filter (Watts Flow Pur FP10GKC).
- Gather necessary tools: a clean towel, a small bucket, and a wrench (if your existing connections require it).
- Familiarize yourself with your existing undersink water filtration system.
Step-by-Step Installation:
- Turn off Water Supply: Locate the cold water supply valve leading to your existing filtration system (usually under the sink) and turn it off completely.
- Relieve Pressure: Open the filtered water faucet to release any pressure in the system. Allow water to drain until the flow stops.
- Disconnect Old Filter: Place a towel and a small bucket under the existing filter to catch any residual water. Disconnect the inlet and outlet tubing from the old filter cartridge. For quick-connect fittings, typically push in the collet (small ring) while gently pulling the tubing out.
- Remove Old Filter: Carefully remove the old filter cartridge from its mounting clips or brackets.
- Prepare New Filter: Remove the new Watts Flow Pur FP10GKC filter from its packaging. Locate the flow arrow on the filter label; ensure it will point in the direction of water flow (towards the faucet) when installed.
- Connect New Filter: Insert the inlet and outlet tubing firmly into the quick-connect fittings of the new filter until they seat securely. Gently pull on the tubing to ensure a tight connection.
- Secure Filter: Mount the new filter securely in place using the existing clips or mounting brackets, if applicable. Ensure it is stable and not hanging freely.
- Restore Water Supply: Slowly turn on the cold water supply valve.
- Check for Leaks: Carefully inspect all connections for any signs of leaks. If leaks are present, turn off the water supply, relieve pressure, and re-seat the tubing or tighten connections as needed.
- Flush the System: Open the filtered water faucet and allow water to run for 5-10 minutes to flush out any carbon fines and trapped air from the new filter. Initially, the water may appear cloudy due to air or carbon dust; this is normal and will clear.
- Verify Operation: Close the faucet and check for leaks again. The system is now ready for use.
Operation
Once properly installed and flushed, the Watts Flow Pur FP10GKC filter operates automatically. Filtered water will be dispensed whenever the connected faucet is opened. For optimal performance, ensure the filter is used within its specified flow rate and pressure limits as determined by your overall filtration system.
It is recommended to run a small amount of water through the faucet each morning or after periods of non-use to ensure fresh filtered water.
Maintenance
Filter Replacement:
The Watts Flow Pur FP10GKC filter cartridge should be replaced every 6-12 months, or sooner if a noticeable drop in water flow or a return of undesirable tastes/odors occurs. Filter life can vary significantly based on the quality of your incoming water and the volume of water used.
Regular replacement ensures continued effective filtration and optimal water quality.
Disposal:
Dispose of the used filter cartridge according to local regulations for general household waste. The materials within the filter are typically non-hazardous.
Troubleshooting
If you encounter issues with your Watts Flow Pur FP10GKC filter, refer to the following common troubleshooting steps:
Reduced Water Flow:
- Cause: The filter may be clogged with sediment or air may be trapped in the system.
- Solution: Flush the filter by running water through the faucet for several minutes. If flow remains low, the filter may be exhausted and require replacement.
Leaks at Connections:
- Cause: Loose connections, improperly seated tubing, or damaged O-rings.
- Solution: Turn off the water supply, relieve pressure, and carefully re-seat the tubing firmly into the quick-connect fittings. Inspect O-rings for damage and replace if necessary.
Cloudy Water or Air Bubbles:
- Cause: Air trapped in the new filter or carbon fines being flushed out.
- Solution: This is normal after installation. Continue to flush the filter for 5-10 minutes until the water runs clear.
Unpleasant Taste or Odor:
- Cause: Filter not adequately flushed during installation or the filter is exhausted.
- Solution: Flush the filter for an extended period (10-15 minutes). If the issue persists, the filter may need replacement.
