WATER SYSTEM
t
PREFILTER
CARTRIDGE
- You must replace
the prefilter cartridge often to protect the RO mem-
brane from being destroyed by chlorine, and/or from
plugging with sediments from the water supply. If
you have chlodne in the water, replace the cadddge
at least every 6 months. If the prefilter cartridge
plugs with sediments, water flow into the 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 cadridge
needs replacing:.
