servicing inner parts. It is important that the person
installing or servicing the system have clean hands
while handling inner parts of the system.
□Make sure that the water supply to the reverse
osmosis system is off.
□Open the reverse osmosis faucet (D). If the
tank is not already empty, allow the water to
empty.
□Use the eye dropper (E) to add 3 ml. of
common household bleach (5.25%) into the
open end of the yellow tubing (K). Handle
bleach according to bleach manufacturer’s
recommendations.
□Connect the yellow tubing to the connector on
the tank (B).
Sanitizing the system will be completed during the
pressure test and purging steps that follow.
NOTE: he bleach must be removed from the
system before drinking the water. See purging
instructions on the next page.

□Purge air from the house plumbing by opening
several house faucets. Close faucets when water
runs smooth, with no spurting.
□Pressure will start to build in the reverse osmosis
system. In about 2 hours check all fittings and
connections. Check for water leaks. Fix leaks if
any are found. If problems exist, refer to the
roubleshooting section of call customer service.
NOTE: When the system is first pressurized, water may
''spurt'' from the faucet air gap hole until air is expelled
from the RO system. Please review the following
operating features before using your Reverse Osmosis
system.
You will not have filtered water immediately. It may take
several hours to fill the storage tank and create maximum
flow from the reverse osmosis faucet.
Water pressure from the reverse osmosis faucet will be
less than your standard faucet.
Water will run to the drain while the reverse osmosis
system is producing water, even if you are not drawing
water from the reverse osmosis faucet.
You may hear a small quantity of water going to the drain
at times when water is not being used. his is normal.
Water going to the drain will automatically shut off when
the storage tank is full.
□Open the reverse osmosis faucet (D) and let water
flow through the system for a 24 hour period. Water
flow will be a slow trickle at this time.
□Close the reverse osmosis faucet (D) after the 24
hour purging period is complete.
When the purging is finished, your reverse osmosis
system is ready for use.
NOTE: As with all other water system applications,
leaks may occur. Because the system pressure builds
slowly, leaks may not be immediately apparent.
Recheck for leaks 24 hours after purging the system is
complete.

How the RO Water System Works
Your Reverse Osmosis (RO) Drinking Water Filtration 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 impurities are sent down the drain. See the figure in this chapter for an
illustration of the explanations that follow:
Prefilter:
Prefilter:Prefilter:
Prefilter: Water from the cold supply pipe enters the prefilter. he prefilter is a replaceable sediment cartridge with
activated carbon in its composition. he cartridge reduces taste, odor, sand, silt, dirt, other sediments, and up to the
amount of chlorine shown in the specifications.
Reverse Osmosis Cartridge:
Reverse Osmosis Cartridge:Reverse Osmosis Cartridge:
Reverse Osmosis Cartridge: Filtered water flows from the prefilter to the reverse osmosis membrane cartridge. he
reverse osmosis cartridge is a tightly wound special membrane. he membrane reduces the dissolved solids and
organic matter. High quality product water (about one ounce per minute) exits the reverse osmosis cartridge. he
product water flows to the storage tank, postfilter, or reverse osmosis faucet. Drain water, with the dissolved solids
and organic matter, is routed to the drain.
Storage ank:
Storage ank:Storage ank:
Storage ank: he storage tank holds product water. A diaphragm inside the tank holds water pressurized to about
half of supply water pressure when the tank is full. his provides fast flow to the reverse osmosis faucet. When the
tank is empty of water, the pressure at the air valve is 5 - 7 psi.
Postfilter:
Postfilter:Postfilter:
Postfilter: Water goes through the postfilter before going to the reverse osmosis faucet. he postfilter is an activated
carbon type filter. Any remaining tastes and odors are reduced from the product water. Clean, high quality drinking
water is available at the faucet.
Reverse Osmosis Faucet:
Reverse Osmosis Faucet:Reverse Osmosis Faucet:
Reverse Osmosis Faucet: he sink or countertop faucet has a hand operated knob to dispense drinking water. An
air-gap is built into the faucet drain water connection to comply with plumbing codes.
Faucet Electronics:
Faucet Electronics:Faucet Electronics:
Faucet Electronics: Inside the faucet base is a battery-operated 6 month timer. An amber LED indicator is located in
the front of the faucet base. his LED will flash continuously after 6 months have passed. his indicates that it is
time to replace the battery, prefilter and postfilter.
Shutoff Assembly:
Shutoff Assembly:Shutoff Assembly:
Shutoff Assembly: he 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 system drops, and the shutoff opens to allow the tank to be refilled.
Check Valve:
Check Valve:Check Valve:
Check Valve: A check valve is located in the reverse osmosis manifold above the center cartridge. he check valve
prevents a backward flow of product water from the storage tank to drain. A backward flow could damage the
reverse osmosis membrane.
Flow Control:
Flow Control:Flow Control:
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. he flow control is located inside the elbow fitting on the reverse osmosis manifold
drain port.

Replace the battery, prefilter and postfilter cartridges at
least every 6 months of product water use. Replace
more often if they begin to plug with sediment.
he prefilter and postfilter are replaceable sediment
cartridges with activated carbon in their composition.
You must periodically replace the prefilter and postfilter
cartridge. his will protect the RO membrane from
being destroyed by chlorine. It will also prevent the
filters from plugging with sediment. You may notice a
slower output of product water as the prefilter and
postfilter build up with sediment. Replace the prefilter
and postfilter cartridges when this occurs. You should
replace the battery whenever you replace the
cartridges.

he reverse osmosis cartridge is a tightly wound special membrane. he membrane reduces the dissolved solids
and organic matter. he life of the reverse osmosis membrane cartridge depends mostly on the pH and hardness of
the supply water (see Specifications). Cartridge life is shorter with higher pH. For example, if supply water pH is from
6.8 to 7.7, the cartridge may last for well over one year. However, cartridge life may be as short as 6 months if the
pH is as high as 8.5 to 10. Higher pH weakens the cartridge membrane and causes pin-hole leaks. It is time to
replace the reverse osmosis cartridge when the production rate and/or quality of product water drops. Product water
may begin to taste different, indicating solids and organics are passing through the reverse osmosis membrane.
