HOW YOUR HOME DRINKING WATER SYSTEM WORKS
water. High quality drinking water flows from the
postfiher and to the faucet.
NOTE: Before going to the faucet, product water
passes through the electronic box and remaining
TDS is measured by a sensor.
FAUCET
- The sinktop or countertop faucet
dispenses the drinking water.
It has a hand
operated, spring loaded lever to keep the faucet
closed and to prevent waste. You can keep the
faucet open by pushing upward on the lever and
locking it against the spout. To meet plumbing
codas, an air-gap is built into the faucet drain water
tubes. The air-gap prevents a back siphon of drain
" water.
. •.
MONITOR
- When the faucet is opened, lights on
the faucet base Show how the RO system is
working.
• FLASHING GREEN - The RO system is giving you
high quality product water.
NOTE: The green light may stop flashing when the
supply of RO water is nearly gone, and flow from
the faucet decreases. This is a normal condition.
• FLASHING AMBER "FILT"
- The prefilter car-
tridge and postfilter need replacing. Also replace
the control box batteries...see
page 14. This
light comes on after 6 months, or after 900 gallons
of product water use.
• FLASHING AMBER "RO" - The RO membrane
cartridge
needs replacing.
(BE SURE
TO
REPLACE
BATTERIES...SEE
ABOVE,
TO
ASSURE PROPER "RO" LIGHT OPERATION.)
The RO light comes on when the RO membrane
no longer removes at least 75% of the TDS from
the water supply.
NOTE: Disregard the "RO"
light when it flashes
for a few seconds at a time.
AUTOMATIC
SHUTOFF
- When the storage
area has fil!ed with product water, and the RO
faucet is G'loasd,the automaticshutoff isforced clos-
ed. Water flow through thesystem isstopped before
it can enter the RO module, preventing continued
flow to the drain. The shutoff remains closed, and
water is saved, until the faucet is opened again°
CHECK VALVE
- A check valve (FIG. 8) is built
into the product water outlet of the RO housing. The
check valve prevents a backward flow of product
Water, from the storage area, to the membrane. A
backward flow could rupture the RO membrane.
FLOW
CONTROL
- The flow control (FIG. 9)
keeps flow through the RO certddge at the need-
ed rate for high quality product water. A cone
shaped screen fits over the flow controlto help pre-
vent plugging with drain water sediments.
CARE OF YOUR HOME DRINKING WATER SYSTEM
To keep your Home Ddnking Water System work-
ing and making high quality water, you must make
sure supply water is always within the limits shown
on page 17. This gives you the longest life from the
PREFILTER CARTRIDGE, RO MEMBRANE CAR-
TRIDGE, and POSTFILTER. Each of these willwear
out in time and need replacing.
CAUTION:
BEFORE
WORKING
ON THE
SYSTEM,
DO
THE
FOLLOWING
TO
RELIEVE

PRESSURE
IN THE RO
TANK.

b. Open the product water faucet and keep open
until water flow stops.
the water, disconnect the postfiiter and empty
the storage bladder.
.
Looking at FIG. 9, or page 18, remove the pro-
tactive cap and depress the relief valve stem,
allowing air to ENTER the tank (do not block
valve passage).
Release
the valve stem
AFTER flow from the shutoff valve slows to a
slight drip. Replace the protective cap.
CAUTION: This valve is for vacuum relief only. DO
NOT attempt to pressurize the tank.
