Carbon Pre-Filter & AquaFree
™
Post-Filter
–
Change every 6 months

The carbon and AquaFree
™
filter cartridges are replaceable activated carbon cartridges locat-
ed 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 12-36 months
*
The RO membrane is located in stage 2. This membrane reduces the dissolved solids and
organic matter. Membrane life depends on pH and supply water hardness. Higher pH
shortens membrane life by causing pin-hole leaks. If pH is higher than 8.0, membrane life
may be as short as 12 months. If pH is under 7.5, membrane life may last up to 36 months.
When output 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 Hahn Technical Support (888) 245-3114.
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.
