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, bypassing 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.

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.

1If 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.

2To connect the water supply tubing:

Run the 1/4″ yellow tubing from the Reverse Osmosis inlet to the water supply fitting (on illustrations in the Water Supply section on page 6). Connect the tubing as applies (see Water Supply section) and tighten the nut securely.
