2. If additional tubing is required, see parts list at
the end of this manual.
The 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 end square and
smooth, with no nicks or rough spots.
NOTE: Tubing lengths should allow the RO
assembly to be moved for servicing.
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.
CONNECT TUBES
1. Push tubing through collet, until it engages the
o-ring. Continue pushing until the tube bottoms
out against the back of the fitting. 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.
