HOW
YOUR
REVERSE
OSMOSIS
SYSTEM
WORKS
Introduction:
Your Reverse Osmosis
(RO) Drinking
Water System uses your household
water pressure
to
force water through
three filters. Minerals
and impurities
are filtered out. Delicious
tasting drinking
water goes to
the storage tank-ready
for your use. Minerals
and impu-
rities are sent down the drain. The following
paragraphs
will explain in detail how your Reverse Osmosis
Drinking
Water System works.
Prefilter:
Water from the cold supply pipe enters the pre-
filter. See Figure 24. The prefilter has a replaceable
sedi-
ment cartridge
with activated
carbon in its composition.
The cartridge
reduces
taste, odor, sand, silt, dirt, other
sediments,
and up to the amount
of chlorine
shown in
the specifications.
Reverse
Osmosis
Cartridge:
Filtered
water flows from
the prefilter,
to the Reverse Osmosis membrane
car-
tridge. See Figure 24. The Reverse Osmosis
cartridge
is a
tightly wound
special membrane.
The membrane
reduces
the dissolved
solids and organic matter. High
quality product
water (about one ounce per minute) exits
the Reverse Osmosis
cartridge.
The product
water flows
to the storage tank, postfilter
or Reverse Osmosis
faucet.
See Figure 24. Reject water, with the dissolved
solids and
organic matter, is routed to the drain. See Figure 24.
Storage
Tank: The storage tank holds product
water. See
Figure 24. A diaphragm
inside the tank holds water pres-
surized
to about 30 psi when the tank is full. This pro-
vides fast flow to the Reverse Osmosis
faucet. When the
tank is empty of water, it is pressurized
to 5 - 7 psi.
Postfilter:
Before going to the Reverse Osmosis
faucet,
product
water goes through
the postfilter.
See Figure 24.
The postfilter
is an activated
carbon type filter. Any
remaining
tastes and odors are reduced
from the prod-
uct water. Clean, high quality drinking
water is available
at the faucet.
Reverse
Osmosis
Faucet: The sink or countertop
faucet
has a hand operated
knob to access drinking
water. See
Figure 24. An air-gap is built into the faucet drain water
connection
to comply with plumbing
codes. See Figure
24.
Faucet Electronics:
The RO system will monitor
the total
product
flow of the unit and also length of time the fil-
ters have been installed.
The faucet base has an indicator
light that flashes to inform you of the status of the RO
membrane
and filters.
Green - RO membrane
and filters are good.
Amber - Warning,
filters need replacing.
Filters need
replacing,
when water has been drawn, after 6 months
time (or 650 gallons have been used).
Red - RO membrane
needs to be replaced.
Shutoff
Assembly:
The unit has an automatic
shutoff
system to conserve
water. When the storage tank has
filled to capacity, and the drinking
water faucet is closed,
pressure
closes the shutoff to stop flow to the drain.
After enough
drinking
water is used, pressure
in the sys-
tem drops, and the shutoff opens to allow the tank to be
refilled. See Figure 24.
Check Valve: A check valve is located in the Reverse
Osmosis
manifold,
above the center sump. The check
valve prevents
a backward
flow of product
water from
the storage tank to drain. A backward
flow could dam-
age the Reverse Osmosis
Membrane.
See Figure 24.
Flow Control:
Water flow to the drain is restricted
by the
flow control, it maintains
the desired flow rate to obtain
the highest
quality drinking
water. The flow control is
located in the end of the 1/4" red drain tubing,
at the
Reverse Osmosis
manifold
drain port. See Figure 24.
