Carbon Pre-Filter & Claryum
®
Post-Filter -
Change every 6 months
*
The carbon and Claryum 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.
Remineralizer -
Change every 12 months
*
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.
If you are adding the remineralizer to a system that has already been installed, shut off the filter
faucet, turn on the water supply and allow the RO tank to fill up completely. Once the tank is
completely filled, flush & saturate the remineralizer cartridge by opening up the filter faucet
and allowing the purified water to run through the remineralizer for 3 minutes. The water may
come out cloudy during the initial flush.
*Filter life depends on water usage and water supply quality.
Faucet is not part of NSF Certification
Nitrate/Nitrite Test Kit:
This system is acceptable for treatment of influent concentration of no more than 27mg/L
nitrate and 3mg/L nitrite in combination measured as N.* This system is supplied with a nitrate/
nitrite test kit. Product water should be monitored periodically according to the instructions
provided with the test kit.
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.
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.
