1 - 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
thep 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.
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 2.8 bar (40 psi) minimum to 5.5 bar (80 psi)
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 4°C (40°F) and 38°C (100°F). Do not install on hot
water lines.
The reverse osmosis membranes contain a food grade 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 as a performance conditioner. All new membranes will reach their stable
maximum performance after 8 hours of rinsing.

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 odours 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.
WARNING: The RO system is designed to work without the 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.

Location of system
The reverse osmosis system is designed for installation under a sink, usually in the kitchen or bathroom. The RO
assembly can be placed on the cabinet floor in any position that does not apply pressure on the disconnect
elbows. The RO product water faucet installs on the sink or on the countertop next to the sink.
The RO system can also be located in a location away from the faucet. A nearby water source and drain point are
required.
NOTE:
• Keep the lengths of tubing short. Longer lengths of tubing will decrease system performance. A booster pump
can be used on the supply line.
• All plumbing should be done in accordance with state and local plumbing codes.
Some codes may require installation by a licensed plumber. Check with the local plumbing authority prior to
installation.
WARNING: All components and tubing should be located in an area which is not exposed to freezing
temperatures. Do not expose unit or tubing to direct sunlight.
Water Supply: To provide supply water to the RO system inlet, a feed supply fitting is required or install pipe fittings
as needed. The feed water valve should be located as close to the manifold assembly as possible. USE A POTABLE
COLD WATER SUPPLY ONLY. Softened water is preferred as it will extend the life of the RO membrane element.
Drain Point: A suitable drain point is needed for reject water from the RO system. A floor drain, laundry tub,
standpipe, sump, etc. are all acceptable. If discharging into the utility sink or standpipe, an air gap of greater than
1/2” above the flood rim must be provided.
A sink p-trap drain adapter is included to install as an optional drain point where codes permit.
Do not connect the system drain line to the dishwasher drain or near the garbage disposal. Back pressure from
these units may cause the air gap to overflow.
Faucet: The faucet should be placed near the sink where drinking water is normally obtained. Convenience of use
(filling of water pitchers and glasses) and an open area beneath the faucet under the sink for attaching product
and drain tubing are considerations.
A 2” diameter flat surface is required above and below the installation site. The thickness of mounting surface
should not exceed 1“1/4. Avoid any strengthening webbing on the underside of the sink.
RO Manifold Assembly: The manifold can be installed on either the right or left side of the under-sink area or
cabinet. Installation in the basement is also an option. One possible location is near the laundry/ utility sink where
cold potable water and drain access are close. The location chosen should allow adequate clearance and
accessibility for membrane element changes.
In restricted under-sink areas, it may be easier to install the faucet first. Allow adequate tubing lengths for final
system placement.
