TO CARE FOR THE RO SYSTEM

REPLACEMENT OF THE PREFILTER, POSTFILTER, AND RO MEMBRANE ELEMENTS
18
Rev J
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 reduces 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 for residential
applications.
Whenever the prefilter is replaced, the postfilter should also be replaced.
Installations using more than 20 gallons product water per day should install
external filters (not supplied) to reduce chlorine and sediment larger than 10
microns.

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: Softened water is recommended for optimal system
performance and RO membrane element life.
1. Turn off the water supply to the RO System.
2. Reduce system water pressure by opening the faucet.
CAUTION: Even with the water supply turned off the membrane and
prefilter sumps will contain a considerable amount of water. By
positioning the RO assembly in a sink or tub, most of the water will be
contained.
3. Disconnect locking bar and place the fittings (with tubing still connected) into
a tub or bucket.
4. Move system into a contained area, such as a sink or tub.
