- CARE OF YOUR HOME DRINKING WATER SYSTEM -
PREFILTER CARTRIDGE - You must replace
the prefilter cartridge often to protect the RO mem-
brane from being destroyed bychlorine, and/or from
plugging with sediments from the water supply. If
you have chlorine in the water, replace the cartridge
at least every 6 months. If the prefilter cartridge
plugswith sediments, water flow intothe RO system
drops, slowing the making of quality RO water. The
RO membrane may also begin to plug with
sediments. If this happens, you may not get enough
RO water for your needs.
NOTE: The amber "FILT" light on the faucet base
will begin to flash after 6 months or 900 gallons of
product water use to tell you the filter cartridge
needs replacing.
