HOW TO CUT AND CONNECT THE TUBES
Your Reverse Osmosis Water System includes push-in fit-
tings for quick tubing connection. Review the following
instructions before connecting the tubes in the next step.
Cut tubes to length
1. Use a sharp cutter or knife to cut the end of tubing.
Always cut the tubing square. See Fig. 17.
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. See Fig. 17.
Note: Tubing lengths should allow for the removal
of the assembly from the hanger washers for serv-
icing. If tubing lengths are shortened for neater
appearance, it may be necessary to keep the
assembly on the hanger washers for service.
Connect tubes
1. Push tubing through collet, until it engages the o-ring.
See Fig. 18. Continue pushing until the tube bottoms
out against the back of the fitting. See Fig. 19. A com-
mon mistake is to stop pushing when the tube engages
the o-ring. This will lead to future leaks. When a 1/4”
tube is fully engaged, 11/16” of the tube has entered
the fitting. When a 3/8” tube is fully engaged, 3/4” of
the tube has entered the fitting. See Fig. 18 & 19.
2. If using tubing other than tubing supplied with the sys-
tem, be sure it is of high quality, exact size and round-
ness with a smooth surface.
Disconnect Tubes
1. Push the collet inward with a finger tip. See Fig.21.
2. Continue holding collet inward while pulling the tubing
out. See Fig. 21.
