Installation Instructions

Residential Reverse Osmosis

Drinking Water System

Your Reverse Osmosis System has been tested to
ensure it will operate correctly. The following
periodic maintenance is recommended so your
system will provide years of trouble-free service:

Replacement parts Replacement

Pre-filter (sediment) Every 6 mos.
Pre-filters (activated carbon) Every 6 mos.
R/O membrane Every 2-3 years
Post filter (carbon) Every 6 mos.

Components

Thefollowing components make up your Reverse
Osmosis DrinkingWaterSystem:

Pre-filter (sediment) removes larger particles such
as sand, silt, rust and scale.

Pre-filters (activated carbon) remove chlorine in the
feed water to protect the reverse osmosis
membrane.

Reverse Osmosis Membrane reduces dissolved
minerals, metals and salts. During the process,
harmful compounds are separated by the
membrane and the reject water goes to waste
(drain).

Filter housings and R/O module hold pre-filters
and membranes. A bracket is provided so they
maybemounted, typically below sink.

Storage tank holds filtered water, ready for use.

Automatic shut-off valve senses when the

storage tank is full and closes the water supply to
conserve water.

The dedicated faucet is used to dispense RO
produced water when needed.

Feed water saddle valve is connected to the cold
water line to supply water to the R/O system.

Waste water saddle valve is connected to the
drain to remove reject water from the R/O system.

Tubing supplies feed and reject water.

Fittings are used for necessary hose connections.

Tools

The following tools may be necessary, depending
on each particular installation:

Center punch and hammer

Concrete drill bits
Phillips head and flat blade screwdrivers
Adjustable wrench
Crescent wrench
Teflon tape
Plastic tube cutter
Air pressure gauge (low pressure)
Air pump (hand)

System location

Your R/O system may be installed under a sink, in a
basement or other location, depending on available
space. Do not install unit where temperatures fall
below freezing; otherwise, damage will result.
Connection to an icemaker should also be
considered for optimum performance.

Guidelines for component placement are as follows:

Faucet should be placed near the sink where
drinking / cooking

water is normally required. A 2"
flat surface is required to mount the faucet if an
existing hole for a second faucet is not available.
The thickness of the mounting thickness should not
exceed 1-1/4".

Storage tank may be placed where it is convenient,
within ten feet of the faucet. Under the sink or in a
nearby cabinet are excellent choices. If tank is
located further than 10 feet from the faucet, use 1/2"
tubing to reduce pressure drop. Full tanks may
weight more than thirty pounds, so a sturdy shelf is
required.

R/O unit may be mounted on either side of the sink,
in a cabinet or heated basement, with nearby
access to a potable, cold water line.

Feed water connection is accomplished with a
self-piercing feed water saddle valve. Locate this
assembly as close to the R/O unit as possible.
Connect to a potable, cold water supply line only.

Note: Softened water is preferred since it will
extend the life of your R/O membrane.

Drain connection is accomplished using a waste
water saddle valve which is designed to fit around a
standard 1-

1/2" OD drain pipe. The drain saddle
valve should always be installed above (before) the
tap and on the vertical or horizontal tailpiece.

An activated carbon post-filter is provided for a
final "polish" and to remove foul tastes, odors and to
provide great tasting drinking water.

faucet is not provided
