- 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.

c.Using a 2 gallon (minimum) container to catch

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.

3.Reconnect the postfilter.
