HOW REVERSE OSMOSIS (RO) WORKS
The ROM IV 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 ROM IV 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
ROM IV 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.
INSTALLATION
NOTE: Please read all instructions, specifications, and
precautions before installing and using your
ROM IV RO System.
NOTE: The ROM IV RO System may be installed under a sink,
counter or water cooler.
NOTE: The ROM IV RO System is installed vertically.
NOTE: Numbered diagrams correspond with
numbered steps.
ROM IV REVERSE OSMOSIS SYSTEM INSTALLATION AND OPERATION GUIDE
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 .
