Pentair Reverse Osmosis System
Installation and Maintenance Manual
SAFETY GUIDES
Read and follow all steps and guides carefully before installing and
using your reverse osmosis system.
Do not use this product to make safe drinking water from non-potable
water sources. Do not use the system on microbiologically unsafe
water, or water of unknown quality without adequate disinfection
before or after the system.
This reverse osmosis system contains replaceable components
(membrane elements). These components are critical for the
effective reduction of total dissolved solids and specific contaminants
that are listed in the Product Data Sheet.
The Reverse Osmosis System does not have a monitoring device for
contaminants. To verify that the system is performing satisfactorily
the product water should be tested periodically by the system's
installing dealer or a certified laboratory, every six months. The
laboratory should be certified for testing the specific contaminants of
concern. For a listing of certified laboratories, contact local regulatory
agencies. Within the United States, many state-run Department of
Natural Resources or Department of Health Services maintain listings
of certified laboratories.
Consult your local public works department for plumbing and
sanitation codes. Follow your local codes if they differ from this
manual.
The reverse osmosis system works on water pressures of 40 psi
(2.8 bar) minimum to 80 psi (5.5 bar) maximum. Water pressure can
be reduced by installing a pressure reducing valve in the water
supply pipe to the RO system. A booster pump should be used for low
pressure applications.
Do not install the reverse osmosis system in extreme hot or cold
temperatures. Temperature of the water supply to the reverse
osmosis system must be between 40°F (4°C) and 100°F (38°C). Do not
install on hot water lines.
The reverse osmosis membranes contain a foodgrade preservative
for storage and shipment. All new membranes require a minimum 2
hour rinse to properly rinse out the preservative. The preservative
is not harmful but makes the product water taste objectionable.
Rinsing the membrane also acts a performance conditioner. All new
membranes will reach their stable maximum performance after 8
hours of rinsing.
THE BASIC REVERSE OSMOSIS SYSTEM
Your Reverse Osmosis System is a water treatment unit. It uses water
pressure to reverse a natural physical process called osmosis. Water,
under pressure, is forced through a semi-permeable membrane to
filter out minerals and impurities. Treated drinking water goes to the
faucet. Minerals and impurities are sent to the drain with RO waste
water.
The system includes replaceable filters and membrane elements. The
prefilter reduces sand, silt, dirt, rust particles, other sediments, and
chlorine from the water supply before they enter the RO membrane
elements. The postfilter reduces any tastes and/or odors that
may remain in the water after passing through the RO membrane
elements.
BEFORE INSTALLING THE RO SYSTEM
• Best performance of the system will be achieved when the
incoming water has been treated (softened).
• The water coming into the system must be within certain limits
for sediments, pressure, etc. Refer to the specifications to
determine if your installation is within the limits.
• A water quality analysis can be performed to determine if
incoming water requires any treatment. Contact your dealer/
installer.
• The filters and membrane elements in the RO system need
to be replaced on a regular basis. Follow the instructions for
replacement that are in this manual.
NOTE: For optimal system performance, use the system for at least 2
minutes continuously each day.
The RO system is designed to work without the
WARNING:
aid of a pressurized storage tank. Installation of
a pressurized storage tank will negatively affect
system performance.
Tools and Materials Required
• Adjustable wrench, and larger adjustable jaw pliers or pipe
wrench to fit sink drain
• Saw for cutting drain pipe
• Slotted and Phillips head screwdrivers
• Tubing cutters
• Electric drill and bits for cutting the faucet mounting hole
NOTE: Note that some sinks will have a pre-drilled hole with a
plug for the faucet.
