HOW REVERSE OSMOSIS (RO) WORKS
The LVRO-75HE RO System uses a semi-permeable
membrane to reduce dissolved salts, improving the taste and
odor of your water. The RO membrane cartridge contains
multiple layers of micron-thin film wound around a hollow
center core. Water molecules can pass through the cartridge,
while dissolved salts are rejected.
Your water supply is prefiltered to reduce dirt and chlorine
that may foul the membrane. The RO membrane cartridge
separates this prefiltered water into PRODUCT WATER and
REJECT WATER. Water pressure forces water through the
membrane within the RO membrane cartridge, and into
the storage tank. This is the product water. Dissolved salts
cannot pass through the membrane and are sent to the
drain as reject water. When the faucet is opened, product
water (permeate) 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 LVRO-75HE RO 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 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. Depending on the system's efficiency, for each
gallon of water produced, up to 1 gal (3.79 L) is discharged as
reject water. The storage tank can hold up to 3.2 gals (12.1 L)
of water at a time.
NOTE: When used under operating conditions specified
in this manual, the RO membrane cartridge of the
LVRO-75HE RO System should last 12 to 24 months.
The precise life span of the RO membrane cartridge
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.
Selecting the Faucet Location
NOTE: 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 1-3/8" hole.
Most sinks have pre-drilled 1-3/8" or 1-1⁄2" diameter
holes that may be used for faucet installation. If
these pre-drilled holes cannot be used or are in an
inconvenient location, it will be necessary to drill a
1-3/8" hole. This procedure may generate dust which
can cause severe irritation if inhaled or come in
contact with the eyes. The use of safety glasses and
respirator for this procedure is recommended.
WARNING: Do not attempt to drill through an
all-porcelain sink. If you have an all-porcelain
sink, mount the faucet in pre-drilled sprayer
hole or drill through countertop next to sink.
WARNING: 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.
WARNING: Do not drill through a countertop that is more
than 1-inch thick.
WARNING: Do not attempt to drill through a tiled, marble,
granite or similar countertop. Consult a plumber
or the countertop manufacturer for advice or
assistance.
1. Line bottom of sink with newspaper to help prevent
metal shavings, parts, or tools from falling down drain.
2. Place masking tape over the area to be drilled to help
prevent scratches if drill bit slips.
3. Mark hole with center punch. Use a 1/4" drill bit for a
pilot hole.
4. Using a 1-3/8" hole saw, drill a hole completely through
the sink. Smooth the rough edges with a file.
INSTALLATION
NOTE: Please read all instructions, specifications, and
precautions before installing and using your
LVRO-75HE RO System.
NOTE: The LVRO-75HE RO System may be installed under a
sink, counter or water cooler.
NOTE: The LVRO-75HE RO System is installed vertically.
NOTE: Numbered diagrams correspond with

stud or firm surface. The mounting bracket will
support the weight of the cartridges and help
prevent strain on the water lines.
1. Select location where unit is to be mounted. The head
assembly is mounted in a vertical position.
2. When mounting the LVRO-75HE RO System, two (2)
screws are required to mount the head. Measure up from
the floor of the cabinet 15.5" (39.4 cm). See Figure 4.
This will provide clearance to change the cartridges. The
two (2) screws will be 14" (35.6) apart and level. Screw
the two (2) screws into the wall. Leave a gap between
the screw head and the wall of 1/8". The backside of the
system head has two (2) slots that will fit over the screw
heads and slide down to lock.

Connecting the Faucet
CAUTION: Water supply to the inlet of the LVRO-75HE RO
System should have a separate shut-off valve. If it
does not, a separate shut-off should be installed.
1. Locate the 3/8" blue tubing from the faucet. See Figure
5. The tubing must not have sharp bends or kinks that
would restrict water flow. Cut length as needed. Place a
mark 3/4" (1.9 cm) from the end of the tubing.
IMPORTANT: A length of this 3/8" blue tubing will be
used to connect the storage tank to the manifold. When
cutting this tube, plan for the new piece to be used for
the tank.
Moisten the end of the tubing with water and insert
into the water outlet quick-connect fitting on the head
assembly . Push in until the mark is flush with the
quick-connect fitting.
2. Gently pull back on the tubing to ensure it is connected
properly. If the tubing comes out of fitting, cut a small
section off of the tubing and reconnect.
NOTE: Tubing may be quickly and easily removed from the
fitting if necessary. First, turn off the water supply to
the filter. Open faucet, then press in the collet around
the fitting while pulling the tubing with your other hand.

PUTTING THE SYSTEM INTO OPERATION
CAUTION: Make certain head assembly is firmly attached
to wall to prevent it from falling and possibly
becoming damaged.
NOTE: The MRS-75EN RO System does not produce a high
volume of water on-demand as an ordinary filter
does. Water is produced at a slow, drop-by-drop rate.
The system requires about three (3) hours to fill the
storage tank. As water is taken from the tank, the
system automatically starts the cycle of replacing the
water and then stops water production when the tank
is full.
There are several steps that must be followed to properly
place the LVRO-75HE RO System into operation. Before the
supply water is turned ON, see Figure 13:
• Remove quick-connect plug on the left end of the
manifold and connect the port with tubing to a drain.
• Turn shut-off valve to the OFF position.
• Turn tank valve to the OFF position.
• The faucet lever should be closed.

of air trapped in the postfilter cartridge. It is not
harmful and will disappear in a matter of minutes. It
may take up to a week after installing a new
postfilter cartridge for the trapped air to dissipate.
The system is ready for operation. You can now enjoy quality
water from the LVRO-75HE RO System.
TESTING YOUR REVERSE OSMOSIS SYSTEM
Total Dissolved Solids (TDS) Test
NOTE: Under NSF/ANSI Standard 58, it is highly
recommended that the product water is tested at
least every six (6) months to verify that the system is
performing satisfactorily.
WHEN TO CHANGE THE CARTRIDGES
The life of the cartridge depends on the water volume used
and the substances in the water. Normally, cartridges should
be changed at intervals of 12 months. Replace the cartridge
sooner if the water pressure at the faucet begins to drop
noticeably or if you notice changes in the taste, color, or flow
of the filtered water.
CHANGING THE CARTRIDGES
Replacement Cartridges:
Everpure 2FC5-S Filter Cartridge - EV9691-86
Everpure 2CB5 Filter Cartridge - EV9617-05
Pentair GRO-75EN RO Cartridge - 4002575
The prefilter and postfilter cartridges need to be changed
when the water pressure at the faucet begins to drop
noticeably or if there are changes in taste, color or flow of
the filtered water. All cartridges should be changed at the
same time. The cartridges are color-coded to indicate which
location they are installed into.
NOTE: Only the replacement cartridges listed can be used
with this system. Failure to use the recommended
replacement cartridges will void your warranty.
1. Place a small pan or towel under the LVRO-75HE RO
System to catch any water tha may drip. Turn OFF
incoming water.
2. Remove the two (2) outside cartridges by twisting each
cartridge a 1/4-turn to the left (counterclockwise). Then
