TUBING CONNECTION
(all push-in fitting locations)
This RO system includes push-in fittings for quick
tubing connection at most locations. If working with
the fittings, do the following.
Connection (FIG. 11 - A):
1. Use a sharp cutter or knife 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.
