6. Re-insert the yellow tubing into its push-fitting in the RO membrane as
follows:
a.) Moisten the O-ring seal inside the concentrate outlet fitting by dripping
a few drops of clean water into the fitting.
b.) Grasp the yellow tubing near the flow restrictor end, and insert the
tubing into the push-fitting. Push the tubing into the fitting until
resistance is felt, approximately 1/2 inch (12.7 mm). The tubing is now
resting on the O-ring seal inside the fitting.
c.) Firmly push the tubing approximately an additional 1/4 inch
(6.35 mm) further into the fitting to completely seat the line into
the fitting and O-ring seal.
7. Turn on the system water supply and check for leaks prior to further use or
testing. If a leak is observed, you may not have pushed the yellow tubing
into the push-fitting far enough to seal the tubing against the O-ring. Turn
off the system water supply and reseat the tubing as described above.

SEDIMENT PRE-FILTER REPLACEMENT
For maximum contaminant removal and long membrane life, the sediment and
carbon pre-filters must be changed when a 15-20% drop in pressure is observed
OR at least 6-month intervals. If your water contains a great deal of sediment or
chlorine, the pre-filters may require more frequent changes to maintain adequate
production rate and extended membrane life.
Sediment Pre-Filter Replacement
Materials Required:
0.5-micron MicroTec™ Sediment Filter (SF-MT-0.5-10), Filter
Wrench
Procedure:
1. Turn off water supply to the system.
2. Refer to photo on page 8. Using the provided filter wrench, remove
the first housing on the left. Unscrew it counterclockwise as viewed
from
the
bottom.
3. Remove the old filter and discard.
4. Thoroughly wash the housing with a mixture of hot soapy water and a
few teaspoons of household bleach. Rinse well with clean hot water.
5. Install the new pre-filter onto the round port on the head of the
housing,
Screw the housing back onto the assembly, and hand tighten
only
.
NOTE: Do not use filter wrench to tighten housings. Over-tightening will
damage housings and void your warranty.
6. Proceed with carbon block filter replacement.
CARBON BLOCK FILTER REPLACEMENT
For maximum contaminant removal and long membrane life, the sediment and
carbon pre-filters must be changed when a 15-20% drop in pressure is observed
OR at least 6-month intervals. When chlorine breakthrough greater than 0.1
ppm occurs in the yellow concentrate line, test for chlorine breakthrough by
collecting a 10 ml sample of the concentrate from the yellow tubing and test the
chlorine concentration using test kit TK-CL-25. If the chlorine concentration is
Materials Required:
0.5 micron Carbon Block Filter (CF-0.5-10), Filter Wrench,
Chlorine Test Kit (TK-CL-25)
Procedure:
1. Perform steps 1-5 listed above
2. Turn on system water supply and check for leaks.
