Installation Instructions
Step B - Make Tubing Connections
1. Locate the piece of supplied 3/8" tubing not used previously. Route it between the union connector
and the water filter outlet (See Figures 2 & 3). Allowing some slack, measure and cut to length. Cut the
ends of the tubing square.
2. Insert tubing all the way into the union connector and water filter outlet. Pull on the tubing to be sure
that it's held firmly in the fittings.
3. Repeat steps 1 and 2 to connect the tube installed on the cold water shutoff to the water filter inlet.
Tubing Connection (all push-in fitting locations):
This system includes push-in fittings for quick tubing connections. When working with the fittings, do the
following.

Step A - Install Water Supply Fittings
Check and comply with local plumbing codes as you plan, then install the fittings to connect the
S
ingle Stage Drinking Water Filtration System into the sink’s cold water supply line. Fittings (9/16-24
thread) and 3/8” O.D. tubing are included to provide connections to and from the water filter’s inlet and
outlet. A typical connection using the included water supply fittings is shown in Figure 3.
1. Close the sink’s water shut off valve(s), or another shut off valve upstream from where you will
install the water filter, and open faucets to relieve pressure from the sink’s cold water supply line.
2. Locate the line connecting the cold water shutoff to the sink faucet. Typically this line will be a flexible
hose. Disconnect the nut that connects this line to the cold water shutoff. Use a bucket to catch water
that drains from this line.
3. Locate one piece of the supplied 3/8” tubing, plus the supplied compression nut, ferrule and tubing
insert (See Fig. 3). Assemble the parts onto the tube, as shown in Figure 3, and thread the compres-
sion nut onto the cold water shutoff. Tighten to provide a leak-tight connection.
4. Locate the water supply adaptor (supplied) and install it into the nut on the supply line which you dis-
connected in Step 2. Refer to Figure 3.
5. Press the stem of the water supply adaptor into one end of the supplied union connector (See Figure
3). Be sure to push the stem all the way in.
