Step E - Connect Tubes
HOW TO CUT AND CONNECT THE TUBES
Your Reverse Osmosis system includes push-in fittings
for quick tubing connection. Review the following
instructions before connecting the tubes in the next
step. Failure to follow these instructions may lead to
future leaks.
Cut tubes to length
1
. Use a sharp cutter or knife to cut the end of tubing.
Always cut the tubing square. See Fig. 16.
2
. Inspect the tube up to 1” from the end to be sure
there are no nicks, scratches or other rough spots. If
needed, cut the tubing again. See Fig. 16.
NOTE: Tubing lengths should allow for the
removal of the assembly from the hanger wash-
ers for servicing. 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. 17. Continue pushing until the tube
bottoms out against the back of the fitting. See Fig.
18. Do not stop pushing when the tube engages the
o-ring. Failure to follow these instructions may 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. Mark tube with a piece of tape or
marker.
2
. If additional tubing is required, see parts list at the
end of this manual.
To Disconnect Tubes
1
. Push the collet inward with a finger tip. See Fig.20.
2
. Continue holding collet inward while pulling the tub-
ing out. See Fig. 20.
