3. Check for leaks.
4. Purge the system. Open the faucet and run the water through the
RO system for one hour.
The RO system is now ready for use.
TO CARE FOR THE RO SYSTEM
The components of the RO system are designed to function with
minimal maintenance. However, the membrane elements and filters
will need to be replaced on a regular schedule.
Run the system for at least two minutes each day for optimal
performance.
REPLACEMENT OF PREFILTER AND POSTFILTER
The carbon/sediment prefilter removes sediment and certain
chemicals, such as chlorine, from the water. Depending on water use
and the amount of impurities, this filter should be replaced every six to
twelve months.
Whenever the prefilter is replaced, the postfilter should also be
replaced.
REPLACEMENT OF RO MEMBRANE ELEMENTS
The functional life of the RO membrane elements will vary based on
feed water quality. Product water should be tested periodically to verify
the membrane elements are performing properly. For most residential
applications, the RO membrane elements should be replaced every
two to four years.
NOTE: When the faucet is initially turned on, water may temporarily
sputter from the air gap until the air is purged. Allow 1 to 3 hours for
any trapped air noise in the system to subside.
NOTE: The one hour flush removes a food grade preservative from
the membrane elements. It is not harmful but may affect the taste of
the water.
NOTE: Softened water is recommended for optimal system
performance and RO membrane element life.
