NOTE: If your water pressure and temperature are at the
low end of the listed range (40 psi [2.8 bar] and 40°F
[4.4°C]), and the TDS level is near the maximum
(1500 ppm), the system will not function properly.
Under these extreme conditions, pre-warming the
supply water using a 25 feet (7.62 m) coil of tubing
between the supply adapter and the system, and/
or installing a booster pump to increase the water
pressure will allow the system to perform effectively.
Do not use with water that is microbiologically
unsafe or of unknown quality without adequate
disinfection before or after the system.
Systems certified for cyst reduction may be
used on disinfected waters that may contain
filterable cysts.
NOTE: Substances reduced are not necessarily in your
water. System must be maintained according to
manufacturer’s instructions, including replacement
of filter cartridges.

• Your water must be within required limits for
satisfactory operation. If not, your membrane life may
be shortened and your warranty will be voided (see
Operating Specifications, page 1).
• Install on cold water line only.
• Make certain that installation complies with all state
and local laws and regulations.
• The reverse osmosis membrane and replacement
cartridges included with this system have limited
service lives. Changes in taste, odor, and color of the
filtered water indicate that the cartridge(s) and/or
membrane should be replaced (see Maintenance, page
10). On the monitored model (PRO) the green light
indicates optimum performance while the amber light
indicates that the membrane is in need of changing.
• During extended periods of non-use (such as during a
vacation), remove the membrane from the membrane
housing and place it in a sealed plastic bag. Store
membrane in refrigerator for future use. DO
NOT FREEZE.
• If system stands for more than 2–3 days without being
used, the storage tank should be emptied.
Membrane Precautions
Chlorine will destroy the Reverse Osmosis
membrane. If you use these RO systems with a
chlorinated or periodically-chlorinated water
supply, it is ABSOLUTELY NECESSARY to use a
carbon prefilter (included with the system). This
carbon prefilter should be changed at least every
3 months to avoid chlorine breakthrough. See
warranty for disclaimers and limitations that apply
to the RO membrane.
NOTE: To make sure no chlorine is present in the water that
reaches the membrane, use a test kit that tests
free-chlorine to check the reject water that flows
from the membrane to the drain. No chlorine should
be detected.
HOW REVERSE OSMOSIS WORKS
The Everpure PRO uses a semi-permeable membrane to
reduce dissolved salts, improving the taste and odor of your
water. The RO membrane is made of multiple layers of
micron-thin film wound around a hollow center core. Water
molecules can pass through the membrane, while dissolved
salts are rejected.
The Everpure PRO system features triple-filter action. Your
household water supply is prefiltered to reduce dirt and
chlorine that may foul the membrane. The RO membrane
separates this prefiltered water into PRODUCT WATER and
REJECT WATER. Your household water pressure forces the
product water through the membrane and into the storage
tank. Dissolved salts cannot pass through the membrane and
are sent to the drain as reject water. When you open the RO
faucet, product water is drawn from the storage tank through
a post-polishing filter. The post-polishing filter takes out any
remaining taste or odor in the water and provides you and your
family with cleaner, great-tasting water.
The PRO system also features an auto shut-off valve, which
shuts off the system once the pressure in the storage tank
reaches 2/3 of the incoming water pressure (your household
water pressure). When you open the faucet to draw water from
the storage tank, the pressure inside the tank drops and the
auto shut-off valve opens. The system then begins to operate,
replenishing the water you took from the storage tank. For
each gallon of water produced, 9 gallons are discharged as
reject water. The storage tank can hold up to
3.2 gallons of water at a time, more than enough for the
average family’s drinking and cooking needs.
When used under operating conditions specified on page 2 of
the manual, your Reverse Osmosis membranes should last
12–24 months.
NOTE: The PRO unit will indicate a need for a membrane
The precise life span of your system’s membrane will depend
on the quality of the water entering the system and the
frequency with which you use it. Frequent use prevents the
dissolved salts from building up on the membrane as scale.
The more water the system is required to produce, the longer
the membrane will last. You may wish to find a variety of uses
for your system in order to prolong the life of the membrane.
The life of the membrane will also depend upon the regularity
with which you replace the prefilter cartridge in the system.

Installing the Water Supply Adapter
NOTE: Read all installation and operating instructions
before installing and using your RO system.
The supply adapter fits 1/2-NPS supply threads. If local codes
permit, it may be used to connect the PRO to the cold water
supply line. If local codes do not permit the use of the supply
adapter, alternate connectors can be obtained from your local
plumbing wholesaler.
See Figure 2.
1. Turn off cold water supply line. If cold water line does not
have a shut-off valve under the sink, you should install one.
2. Turn on the cold water faucet and allow all water to drain
from line.
3. Disconnect cold water line from the threaded stub on
bottom of main faucet.
4. Apply plumber tape onto threads of faucet stub and supply
adapter. Screw the water supply adapter to the threaded
faucet stub as shown.
5. Using the nut that previously connected the cold water line
to the faucet, screw the cold water line to the male supply
adapter threads.

Selecting the Faucet Location
CAUTION
The drinking water faucet should be positioned with function,
convenience and appearance in mind. An adequate flat area is
required to allow faucet base to rest securely. The faucet fits
through a 1-1/4 inch hole. Most sinks have pre-drilled
1-1/2 inch or 1-3/8 inch diameter holes designed for spray
hoses. The drinking water faucet may be installed using one of
these holes, despite their larger size. If these pre-drilled holes
cannot be used or are in an inconvenient location, it will be
necessary to drill a 1-1/4 inch hole for the faucet in the sink or
through the countertop next to the sink.
Mounting the Faucet
1. Loosen brass stem-nut on faucet, remove metal “C”
disc (Figure 4).
Drilling the Faucet Hole
This procedure may generate dusts which can
cause severe irritation if inhaled or if they come
into contact with the eyes. The use of safety
glasses and respirator for this procedure
is recommended.
DO NOT ATTEMPT TO DRILL THROUGH AN ALL-
PORCELAIN OR PORCELAIN-COATED SINK. For
applications on these types of sinks we recommend
using the sprayer hole or mounting the faucet
through the countertop.
When drilling through a countertop make sure the
area below the drilled area is free of wiring and
piping. Make certain that you have ample room to
make the proper connections to the bottom of
the faucet.
Do not drill through a countertop that is more than
1-inch thick.
Do not attempt to drill through a tiled, marble,
granite or similar countertop. Consult a plumber
or the countertop manufacturer for advice
or assistance.
The following instructions apply to stainless steel sinks only.
See Figure 3.
1. Line bottom of sink with newspaper to prevent shavings,
parts or tools from falling down the drain.
2. Place masking tape over the area to be drilled to help
prevent scratches if drill bit slips.
3. Mark point with center punch. Use a 1/4-inch drill bit to
drill a pilot hole through sink.
4. Use a 1-1/4 inch hole saw to enlarge hole. Smooth rough
edges with a file.
Figure 4
2. Holding the faucet, feed the three tubes through the hole in
the sink. Position the faucet handle at the desired
location (Figure 5).
Figure 5
3. Center the faucet and slip “C” disc between the white
spacer and the bottom of the counter or sink. Tighten the
stem nut with a wrench until it is tight (Figure 6).
Figure 6
4. Making sure the faucet handle is in the down position, use
a needle-nose pliers to pull the short plastic tube out of
the top of the faucet base (Figure 7).
NOTE: If handle should come off faucet base, make sure the
T-Bar is parallel to the front of the faucet base before
inserting handle. If T-Bar is not in the correct position
the faucet will not work properly.
