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.
