2. Installation (Cartridge Replacement)

This section outlines the steps for replacing an existing filter cartridge in your Pentair FreshPoint Undersink Water Filtration System. Always ensure the water supply is turned off before beginning the replacement process.

1. Turn off Water Supply: Locate the cold water supply line leading to your FreshPoint system and turn off the water supply valve. This prevents water flow during cartridge replacement.
2. Depressurize System: Open the filtered water faucet to relieve any pressure within the system. Allow water to drain until the flow stops.
3. Remove Old Cartridge: Twist the old F1S5 cartridge counter-clockwise to unlock it from the filter head. Gently pull the cartridge downwards to remove it. Be prepared for a small amount of residual water to drip from the cartridge and filter head.
4. Prepare New Cartridge: Remove the new Pentair FreshPoint F1S5 Replacement Cartridge from its packaging. Ensure the O-rings are properly seated on the cartridge.
5. Install New Cartridge: Align the new cartridge with the filter head. Push the cartridge upwards into the head and twist it clockwise until it locks securely into place. You should feel a positive click or resistance when it is fully seated.
6. Restore Water Supply: Slowly turn on the cold water supply valve. Check for any leaks around the filter head and cartridge connection.
7. Flush System: Open the filtered water faucet and allow water to run for approximately 5-10 minutes to flush out any air and fine carbon particles from the new cartridge. The water may appear cloudy initially; this is normal and will clear.
8. Check for Leaks: After flushing, close the faucet and re-check all connections for leaks.

The FreshPoint system is designed for effortless, click-in cartridge change-outs, making this process straightforward.

3. Operation

Once installed, the Pentair FreshPoint F1S5 Replacement Cartridge operates continuously to filter your water. Water flows through the cartridge, where sediment and PFAS contaminants are reduced, providing clean water on demand through your dedicated filtered water faucet.

Normal operation involves a steady flow of filtered water. A significant reduction in flow rate may indicate that the cartridge is nearing the end of its service life and requires replacement.

4. Maintenance

Regular maintenance of your Pentair FreshPoint system primarily involves the timely replacement of the F1S5 cartridge. The cartridge has a 675-gallon capacity and should be replaced annually or sooner if you notice a diminished flow rate from your filtered water faucet.

Adhering to the recommended replacement schedule ensures optimal performance and continued reduction of contaminants, including PFOA/PFOS and sediment.

Refer to the "Installation (Cartridge Replacement)" section for detailed steps on how to replace the cartridge.

5. Troubleshooting

• Diminished Water Flow: If the flow rate from your filtered water faucet significantly decreases, it is a strong indicator that the F1S5 cartridge is clogged with sediment or has reached its capacity. Replace the cartridge as described in the "Installation (Cartridge Replacement)" section.
• Unpleasant Taste or Odor: While this cartridge primarily targets sediment and PFAS, if you notice a return of unpleasant tastes or odors in your filtered water, it may suggest the cartridge's effectiveness is diminishing or that other filtration stages in your system (if applicable) need attention. Ensure the F1S5 cartridge is replaced as per the recommended schedule.
• Leaks: If leaks occur after cartridge replacement, ensure the new cartridge is properly seated and twisted fully clockwise into the filter head. Check that the O-rings on the cartridge are not pinched or damaged. If leaks persist, turn off the water supply and consult a qualified plumber or Pentair customer support.
