Step A - Install Cold Water Supply Fitting

Check and comply with local plumbing codes as you plan, then install a cold water supply fitting. The fit-

ting must provide a leak-tight connection to the water filter 3/8" tubing. A typical connection using the

included water supply fitting is shown in Figure 3A. An optional connection using standard plumbing fit-

tings (not included) is shown in Figure 3B.

Included Water Supply Fitting

1. Close the cold water shutoff valve (angle stop valve) that the water supply fitting will be installed on,

and open faucet(s) to relieve pressure.

2. Disconnect the existing cold water line from the water shutoff valve.

3. Make sure that the water supply fitting's gasket is inside the female threaded portion of the fitting.

4. Install the water supply fitting onto the cold water shutoff valve, where the existing cold water line was

removed, and hand tighten. Be careful not to cross thread or overtighten.

5. Connect the existing cold water line to the male threaded portion of the water supply fitting and hand

tighten. Be careful not to cross thread or overtighten.

Optional Pipe Fittings (compression type shown)

NOTE: Be sure to turn off the water supply and open a faucet to drain the pipe.

Complying with plumbing codes, install a fitting on the cold water pipe to adapt 3/8" OD tubing. A typical

connection is shown in Figure 3B. If threaded fittings are used, be sure to use pipe joint compound or

thread sealing tape on outside threads.

Step B - Make Hole For Filtered Water Faucet

IMPORTANT: To avoid damaging the sink, consult a qualified plumber or installer for drilling procedures

in porcelain, stainless steel or granite. Special drill bits are made for this.

1. Select one of the following places to install the faucet. Be sure there is room underneath so you can

make the needed connections.

In an existing sink spray attachment hole.

Drill a hole in the sink top.

Drill a hole in the countertop next to the sink.

2. If drilling is needed make a 1-1/4" dia. (minimum) hole for the faucet.
