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 mid all the way into

If using tubing other than tubing supplied with the

system, be sure it is of high qualit?; exact size and

roundness with a smooth surface.
