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 by chlorine0 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
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:
If you have the optional Electronic Monitor,
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.
POSTFILTER
- Always replace the postfilterat the
same time you replace the prefilter cartridge. The
postfilter gives the product water a final filtering of
any tastes and/or odors that may remain.
