Installation Instructions
FILTRATION DRAIN CONNECTION INSTALLATION
Check and comply with all state and local plumbing codes as you plan.
CAUTION:
The options detailed in this section are the ONLY approved installation
configurations. Do not use any drain saddle device.
OPTION A: BASEMENT ACCESS
INSTALLATION
Route the drain line (1/4
″ black line)
DIRECTLY from the Reverse Osmosis system
to a standpipe in the basement, by-passing
the air gap provided in the faucet. The drain
line may also be routed in the basement to a
floor drain or washtub, provided that the air
gap in the basement is maintained. Avoid
dips, loops or low spots in the drain line.
The basement air gap and drain installation
configuration must conform to all local codes.
Special air gap fittings are available from
your local hardware store to connect the
drain line to the top of the standpipe.

OPTION B: DRAIN LINE ADAPTER
INSTALLATION
CAUTION!
DO NOT INSTALL DRAIN LINE ADAPTER
DOWNSTREAM FROM DISPOSER.
Install the provided drain line adapter under the
sink as shown. The baffle-tee provided must be
in place (purchase and install if necessary) to
prevent a clog in the Reverse Osmosis drain
line. Route the drain line (3/8
″ black) from the
faucet air gap to the drain line adapter, ensuring
that there are no dips, loops or low spots in the
line that could result in a clogged drain line.
The tubing must be cut to length to provide
a straight routing from the faucet to the drain.
Drain noise in the sink drain is normal when
the Reverse Osmosis system is operating.
FAUCET DRAIN TUBING AND WATER SUPPLY TUBING
If OPTION A: BASEMENT ACCESS INSTALLATION (see Filtration Drain Connection Installation section,
above) was used, go to Step 2.
If OPTION B: DRAIN LINE ADAPTER
INSTALLATION was used, connect the
faucet drain tubing by running the 3/8
″
black tubing from the 3/8
″ faucet barb
to the drain fitting (installed in Filtration
Drain Connection Installation section,
above). Keep this tubing run as short and
straight as possible, without loops, dips
or low spots. Cut the tubing as needed
and insert into the drain fitting.
1 To connect the water supply tubing:
Run the 1/4
″ yellow tubing from the Reverse
Osmosis inlet to the feed water adapter
(see illustrations in the Feed Water Supply
section). Connect the tubing as applies (see
Feed Water Supply section) and tighten the
nut securely.
