This filter system is designed and tested for use with genuine Aquasana parts including
replacement filters and all hardware. Use of parts from other manufacturers may result in loss
of contaminant reduction performance, system damage or failure. Use of parts from other
manufacturers will also void your warranty. Please visit aquasana.com for all replacement parts.
Carbon Filters -
Change every 6 months
*
The carbon filter cartridges are replaceable activated carbon cartridges located in stages 1 and 3.
It is recommended replacing these cartridges at least every 6 months. You may need to replace
more often with high water usage or high sediment level. Replacing these cartridges timely will
protect the RO membrane from high levels of chlorine and/or sediment. As these filters build
up with sediment, you may notice slower water output.
RO Membrane Cartridge -
Change every 12 months
The RO membrane is located in stage 2. This membrane reduces the dissolved solids and
organic matter. Most municipally treated water has a 7.0-7.5 pH, in this case you would need to
replace your RO membrane every 12 months. Membrane life depends on pH and supply water
hardness. Higher pH shortens membrane life by causing pin-hole leaks, and would shorten
membrane life. When output and water quality and production rate decrease, it is time to
replace the filter sump.
Important:
For the first 36 hours after the initial installation, make sure to periodically inspect
for leaks while the system is running and while it is turned off. If a leak occurs, shut off the
water supply, open up the filter faucet to release pressure from the system & contact Aquasana
Technical Support 866.662.6885.
Flow rate and output are determined by 3 factors:
1
Incoming water temperature
2
Total dissolved solids (TDS) present in supply water
3
Incoming water pressure
Lower temperatures are directly proportional to slower flow rate. All membranes are tested at
77°F. Incoming water temperature should not exceed 100°F. The RO Filter System should also
not be installed in a location susceptible to freezing. The more TDS in the supply water, greater
filter time is required. Incoming TDS should not exceed 1000 ppm. Higher water pressure
enables a higher flow rate. Pressure must be above 40 psi for proper system operation. You may
consider installing a permeate pump or booster pump if your pressure is below 40 psi.
Drain Flow Restrictor
The restrictor is vital for proper operation of the RO membrane cartridge as it keeps water
flowing through the membrane at the proper rate ensuring the water produced is the best
quality. It is recommended the restrictor assembly be periodically inspected to be sure it is
clean and unrestricted. If service is required on the drain flow assembly, disassemble and
reassemble as outlined in Step Six.
*Filter life depends on water usage and water supply quality.
