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 part Frequency
Pre- lter (sediment) Every 6 mos.
Pre- lters (activated carbon) Every 6 mos.
R/O membrane Every 2-3 years
Post lter (carbon) Every 6 mos.
Components
The following components make up your Reverse Osmosis
Drinking Water System:
PREFILTER (sediment) removes larger particles such as
sand, silt, rust and scale.
PREFILTERS (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).
An activated carbon POSTFILTER is provided for a nal
“polish” and to remove foul tastes, odors and to provide
great tasting drinking water.
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:
• 3/8” variable speed electric drill, 1/8” & 1/2” bits
• 1-1/4” porcelain hole cutter (if hole for second
• faucet is not provided
• Center punch and hammer
• 1-1/4” wood bit
• Concrete drill bits
• Phillips head and at blade screwdrivers
• Adjustable wrench
• Crescent wrench
• Te on 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:
FILTER HOUSINGS and R/O MODULE hold pre- lters
and membranes. A BRACKET is provided so they may
be mounted, typically below sink.
STORAGE TANK holds ltered water, ready for use.
AUTOMATIC SHUTOFF 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.

FAUCET should be placed near the sink where drinking/
cooking water is normally required. A 2” at 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 weigh 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.
Installation Instructions
Residential Reverse Osmosis Drinking Water System
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 t 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.
Do not install the drain saddle valve near a garbage
disposal; otherwise, plugging of the waste water line
may occur. If discharging into a utility sink or standpipe,
an air gap must be provided. (Air gaps must be 1” or
greater above the oor rim.)
NOTE: Plumbing codes may require the use air gaps. Please
check with your local municipality.
may require installation by a licensed plumber. Check
local authority prior to installation.
A. Faucet installation
If the sink has a sprayer it may be disconnected for
faucet installation. (Installing dealers should discuss this
with customers.) A pipe cap or plug will be necessary to
seal the sprayer connection.
To make the faucet mounting hole (if sprayer or second
hole is not used), check below to make sure the drill does
not interfere with anything below. Center punch a small
indent at the desired faucet location. (2” at surface is
required, not exceeding the chassis punch and tighten
nut to cut the desired hole size. Clean up sharp edges.
The faucet should be positioned so it empties into the
sink and the spout swivels freely for convenience. If sink
has a hole that can accommodate the RO faucet, no
drilling is required.
Proceed with mounting the faucet.
Do not connect the R/O system drain line to the
dishwasher drain line due to the fact back pressures my
cause the air gap to over ow.
Site preparation
Installing dealers may want to speak with customers in
advance and ask them to clean under the sink to save
time. If a basement installation is advisable, check area
to determine if extra ttings or hosing are required.
Upon arrival, it is a good idea to check the condition of
all plumbing for potential leaks and advise customer so
there will be no misunderstandings in the event leaks
occur.
Unit preparation
Open shipping carton, remove components and check
that all parts are present. Check empty storage tank
to be sure air pressure is approximately 7 PSI. Adjust if
necessary.
Installation steps
NOTE: All plumbing must be completed in accordance
with state and local plumbing codes. Some municipalities
Porcelain, Enamel, Ceramic on Metal or Cast Iron
Precautions must be taken to penetrate the porcelain
through to the metal base and prevent it from chipping
or scratching.
Tools required:
• Variable speed drill
• Relton porcelain cutter tool set
(7/8” or alternative size, 9/16”)
• Plumber’s putty
Procedures
1. Mark the center for the 7/8” hole.
2. Form shallow putty around hole area and ll with
enough water to lubricate carbide drill bit.
3. Carefully drill pilot hole through all layers. (Use light
pressure and slow speed.)
4. Insert pilot tip of spring-loaded porcelain cutter into
pilot hole.
5. Drill porcelain/enamel using spring loaded porcelain
cutter, making certain a complete ring has been cut
through the porcelain / enamel to the metal base.
