TO CARE FOR THE RO SYSTEM
The components of the RO system are designed to function with
minimal maintenance. However, the membrane elements and pre-
filter will need to be replaced on a regular schedule.
For optimal performance the system should be flushed for 2 minutes if
periods of inactivity that extend past six hours.
REPLACEMENT OF PRE-FILTER
The carbon pre-filter 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 a minimum of 2,000 gallons
of purified water produced.
Applications using more than an average of 20 gallons purified water
per day should install the optional Pre-Evolution high capacity pre-
filter to further reduce chlorine, sediment, and other contaminants.
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
applications, the RO membrane elements should be replaced every 6
months to two years.
NOTE: Softened water is recommended for optimal system
performance and RO membrane element life.
REPLACEMENT OF THE PRE-FILTER,
AND RO MEMBRANE ELEMENTS
Turn off the water supply to the RO System. 1.
Reduce system water pressure by opening the included shut off 2.
valve or optional float valve.
CAUTION: Even with the water supply turned off the membrane and
pre-filter 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.
Disconnect locking bar and place the fittings (with tubing still 3.
connected) into a tub or bucket.
Move system into a contained area, such as a sink or tub. 4.
Remove the support leg from the three sumps and unscrew the 5.
top sump as shown to access the pre-filter. The support leg
functions as a wrench to loosen the sump, Figure 13.
NOTE: There is no need to disconnect tubing from fittings on the
manifold. Remove locking bar and pull fittings out. Lubricate
O-rings with silicone prior to re-assembly.
NOTE: If changing only the pre-filter the other sumps do not need
to be removed. If changing the membrane elements, the pre-
filter should also be changed.
Remove exhausted pre-filter and discard. 6.
CAUTION: The person handling the filters and membrane elements
must have clean hands to keep the system sanitized. The
use of sterile/latex gloves is recommended.
