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 pre-filter 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 the pre-filter 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: (FIRST FILTER ON LEFT)

1.Turn off water supply to the system.

2.Refer to photo on page 6. 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 into 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 carbon pre-filter must be changed at least ever 6-month or 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-10. If the chlorine concentration is above 0.1ppm, replace the carbon pre-filter.
