Membrane Troubleshooting Guide
The following chart illustrates the procedure for determination of RO membrane
performance. However, the chart represents only rough guidelines for determin-
ing performance of RO membrane. Depending on your tap water chemistry, the
rejection characteristics of the membrane may vary significantly.

To re-insert the tubing into its push-fitting:
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.
