Operating Instructions
Once installed, the Aquasana 3-Stage Max Flow Claryum Under Sink Water Filtration System, with these replacement cartridges, operates continuously to provide filtered water on demand. Simply turn on your filtered water faucet to dispense clean water.
Benefits of Filtered Water:
- Enjoy better tasting drinking water.
- Enhance the flavor of beverages like coffee, tea, and smoothies.
- Improve the taste of cooked foods, including steamed vegetables, rice, boiled pasta, and soups.
- Provide healthier water for your pets.
Maintenance
Regular replacement of your filter cartridges is crucial to maintain optimal performance and ensure continuous access to clean, healthy water.
Filter Replacement Frequency:
As a general rule, these filter cartridges should be replaced approximately once every six months. However, the actual replacement interval may vary depending on your water quality and usage volume. The included sediment pre-filter helps extend the life of the main filters, providing a capacity of up to 800 gallons.
The easy twist-off design allows for quick and mess-free filter changes without needing to disconnect hoses or shut off the main water supply.
Troubleshooting
If you experience issues such as reduced water flow or changes in water taste/odor, consider the following:
- Reduced Flow: This often indicates that the filters are nearing the end of their lifespan and need replacement.
- Unusual Taste/Odor: If the water develops an unusual taste or odor, it's a strong indicator that the filters require immediate replacement.
- Leaks: Ensure all filter cartridges are properly seated and twisted securely into the system head. Check O-rings for any damage.
