Tubing Connection (all push-in fitting locations)
This RO system includes push-in fittings for quick tubing connection. If working with the fittings, do
the following.
Connect Tubing:
1. Use a utility knifc to cut the end of tubing square.
2. Inspect the end (about 1") of the tubing to be sure there are no nicks, scratches or other rough spots.
If needed, cut the tubing again.
3. Push tubing through the collet and all the way into fitting. Full engagement is 11/16" for 1/4"
tubing, and 3/4" for 3/8" tubing.
If using tubing other than tubing supplied with the system, be sure it is of high quality, exact size and
roundness with a smooth surface.
To Disconnect Tubing:
1. Push the collet inward and hold with a finger while pulling the tubing out.
