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

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.
