Review to the following instructions before connecting the
tubes to their dedicated fittings. Failure to follow these
instructions may lead to future leaks. See Figure 2 for more
information.
Both the Reverse Osmosis Assembly and fresh water storage tank will need to be installed in
a kitchen or bathroom sink cabinet. The reverse osmosis waste water line will need to be hard
connected to a sink drain-line by using the drain saddle adapter enclosed in the package.
Note: The drain saddle adapter will need to attach above the sink drain P-Trap to drain
water from the reverse osmosis system. Review the following schematic, Figure 1, for
more information.
How to Cut the PE Tube
1. Carefully use a tube-cutter or knife blade to cut the end of
tubing. Always cut the tubing square.
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.
1. You will notice that the PE tubes have black marks close to
the end of the tube. The black mark is to help assist you in
knowing if the PE tube is seated or fully engaged into the
fitting.
2. Push tubing through collet until it engages the O-Ring. See
Figure 3.
3. Continue pushing until the tube bottoms out against the
back of the fitting. See Figure 4.
4. Do not stop pushing when the tube engages the
O-Ring. Failure to follow these instructions may lead to future
leaks.
