- HOW YOUR HOME DRINKING WATER SYSTEM WORKS -
POSTFILTER - continued
water. High quality drinking water flows from the
postfilter 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
codes, 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 BA-I-FERIES...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 filled with product water, and the RO
faucet is closed, the automatic shutoff is forced clos-
ed. Water flow through the system is stopped 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 cartridge at the need-
ed rate for high quality product water. A cone
shaped screen fits over the flow control to help pre-
vent plugging with drain water sediments.
- CARE OF YOUR HOME DRINKING WATER SYSTEM -
To keep your Home Drinking 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 will wear
out in time and need replacing.
CAUTION: BEFORE WORKING ON THE
SYSTEM, DO THE FOLLOWING TO
RELIEVE WATER PRESSURE IN THE RO
TANK.
la. Turn off the water supply to the RO (turn the
supply saddle valve all the way inward...FIG. 7).
b. Open the product water faucet and keep open
until water flow stops.
the water, disconnect the posffilter and empty
the storage bladder.
,
Looking at FIG. 9, or page 18, remove the pro-
tective 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.
