Reverse Osmosis User Guide

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 post filter 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 limit 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.

      

 

 Installation Note:

 A water filter system/tap, like any product, has a limited life and may 

eventually fail. Also sometimes failure happens early due to unforeseen circumstances. 

To avoid possible property damage, this product should be regularly examined for leakage 
and/or deterioration and replaced when necessary. A drain pan, plumbed to an appropriate 

drain or outfitted with a leak detector, should be used in those applications where any 

leakage could cause property damage, and/or the water supply should be turned off if no 
one is home/present.   

INSTALLATION SHOULD BE COMPLETED BY QUALIFIED TRADESPEOPLE. 

FAULTY OPERATION DUE TO UNQUALIFIED PERSONS WILL RESULT IN VOIDED 

WARRANTY COVERAGE.
