Your Reverse Osmosis
Water System uses your household
force water through
three filters. Minerals
are filtered out. Delicious
water goes to
the storage tank-ready
for your use. Minerals
rities are sent down the drain. The following
will explain in detail how your Reverse Osmosis
Water System works.
Water from the cold supply pipe enters the pre-
filter. See Figure 24. The prefilter has a replaceable
carbon in its composition.

organic matter, is routed to the drain. See Figure 24.
