4. Installation

Follow these general steps for installing your Naturewater CTO-PAD2 filter cartridge. Specific installation may vary depending on your existing water filtration system housing.

1. Turn off Water Supply: Locate the main water shut-off valve and turn it off to prevent water flow to the filter housing.
2. Depressurize System: Open a nearby faucet to release any pressure in the water lines.
3. Open Filter Housing: Use a filter wrench (if necessary) to unscrew and open the filter housing.
4. Remove Old Cartridge: Carefully remove the old filter cartridge and dispose of it.
5. Clean Housing: Clean the inside of the filter housing with warm, soapy water and rinse thoroughly. Inspect the O-ring for any damage and replace if needed. Lubricate the O-ring with a silicone-based lubricant if desired.
6. Insert New Cartridge: Place the new Naturewater CTO-PAD2 filter cartridge into the housing, ensuring it is seated correctly.
7. Close Housing: Screw the filter housing back onto the cap, hand-tightening it. Do not overtighten.
8. Restore Water Supply: Slowly turn on the main water supply.
9. Flush System: Open a nearby cold water faucet and let the water run for 5-10 minutes to flush out any air and carbon fines. The water may appear cloudy initially; this is normal and will clear up.
10. Check for Leaks: Inspect the filter housing for any leaks. If leaks occur, turn off the water, tighten the housing slightly, and recheck.

5. Operation

Once installed, the Naturewater CTO-PAD2 filter cartridge operates continuously as water flows through your system. It requires no active user intervention during its operational lifespan. Ensure that the water flow rate is within the recommended limits for optimal filtration.

6. Maintenance

The primary maintenance for your Naturewater CTO-PAD2 filter cartridge is timely replacement.

• Replacement Schedule: Replace the filter cartridge every 6-12 months. This duration can vary based on water quality and usage volume.
• Indicators for Replacement: You may need to replace the cartridge sooner if you notice a significant decrease in water flow, a return of unpleasant tastes or odors, or visible sediment in your filtered water.
• Replacement Procedure: Follow the installation steps outlined in Section 4 to replace the used cartridge with a new one.

7. Troubleshooting

If you encounter issues with your filter cartridge, consider the following common problems and solutions:

• Reduced Water Flow: This often indicates a clogged filter cartridge. It's time for a replacement. Ensure the main water supply valve is fully open.
• Unusual Taste or Odor: If filtered water develops an unusual taste or odor, the filter's capacity may be exhausted. Replace the cartridge. Ensure the system was properly flushed after installation.
• Leaks from Housing: Turn off the water supply immediately. Check if the filter housing is properly tightened. Inspect the O-ring for damage or improper seating. Replace the O-ring if necessary.
• Cloudy Water After Installation: This is usually normal and due to air or carbon fines. Flush the system for a longer period (10-15 minutes) until the water runs clear.
