Operating Instructions

Once installed and flushed, your Aquasana water filter system is ready for use. Simply open the dedicated faucet to dispense filtered water.

Water Flow:

The system provides a maximum flow rate of 0.5 gallons per minute. This ensures a steady supply of filtered water for drinking, cooking, and other uses.

Filter Life Indicator:

The system includes a filter life indicator (powered by 1 Lithium Metal battery, included) to help you track when filter replacements are needed. Pay attention to this indicator for optimal performance.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your Aquasana water filter system.

Filter Replacement:

Filter cartridges should be replaced every 6 months or after filtering 800 gallons of water, whichever comes first. The replacement process is designed to be simple and tool-free.

Step 1: Remove each sump (filter housing) by twisting it off.
Step 2: Remove the top of the sump and discard the old filter cartridge.
Step 3: Insert the new filter cartridge into the sump.
Step 4: Reattach the sump to the filter housing. Tighten by hand only to avoid overtightening.
Step 5: Flush the system again after replacing filters to remove any air or carbon fines.

System Housing Replacement:

The filter housing must be replaced every five years. Failure to do so could result in potential leaks. Contact Aquasana support for replacement parts.

Troubleshooting

Problem	Possible Cause	Solution
Water Leakage	Loose connections, faulty O-rings, pressure-cracked plastic housings (after years of use).	Ensure all connections are hand-tightened properly. Check O-rings for damage. If housing is old (over 5 years), consider replacement.
Sulfur-like taste/odor after filter change	Carbon fines from new filters.	Flush the system by running water for an extended period (more than 10 minutes) until taste/odor dissipates.
Cloudy water (initial use)	Small air bubbles from dry filters.	This is normal. Continue flushing the system; cloudiness will clear as air is purged.
Low Water Flow	Clogged filters, low house water pressure.	Replace filters if they are past their lifespan. Check household water pressure.
