5. Filter Replacement Instructions
The Frizzlife system features a twist-in design for easy filter replacement. Follow these general steps:
- Turn off Water Supply: Locate the cold water supply valve under your sink and turn it off to prevent water flow to the filter system.
- Depressurize System: Open your filtered water faucet to release any remaining pressure in the system. Allow water to drain until it stops.
- Remove Old Filter: Use the housing wrench provided with your system (or by hand if loose enough) to twist the old filter cartridge counter-clockwise until it detaches from the filter head. Be prepared for a small amount of residual water to drip.
- Prepare New Filter: Remove the plastic wrapping from the new filter cartridge. Ensure the O-rings are properly seated.
- Install New Filter: Align the new filter cartridge with the filter head and twist it clockwise until it is securely in place. Do not overtighten.
- Turn on Water Supply: Slowly open the cold water supply valve under your sink. Check for any leaks around the new filter.
- Flush the System: Open your filtered water faucet and let the water run for 3-5 minutes to flush out any air bubbles and carbon fines. The water may appear cloudy initially, which is normal.
