Options
1. Locate and turn off the angle stop valve on the cold water line feeding the sink where the Sierra
unit is to be installed. This valve will usually be located under the sink on the pipe coming out of
the wall.
Hint: Be sure to make this connection on the COLD water feed, not the HOT water feed. If
you are not sure which line is the cold water line, open the hot water tap on the sink until
hot water flows from the faucet. The hot water line under the sink can then be identified
by touch.
2. When the angle stop valve is closed, relieve pressure in the line by
opening the cold water tap on the sink.
3. It may be possible to install the feed adapter fitting at either the
angle stop valve or at the faucet inlet connector depending on the size
and type of fittings at your location. The angle stop valve is prefer-
able because of its easier accessibility. Both options are given in Fig 1.
Option A - To install the feed adapter at the faucet connector discon-
nect the cold water feed line where it connects to the faucet inlet
connector. This will usually require an open end wrench, pliers, or
long reach faucet wrench. Proceed to step 4.
Option B - To install the feed adapter at the angle stop valve, discon-
nect the feed line at the angle stop valve. This will usually require a
wrench or pliers. With this end of the water line free, proceed to step
4.
4. Take the 1/4" feed connector valve from the parts kit and install it into the brass feed connec-
tor adapter. Use a crescent wrench or open-end wrench to tighten the valve into the adapter
(Option B shown in Fig. 1). If the feed adapter is to be installed at the faucet inlet connector
(Option A shown in Fig. 1) it may be necessary to install the feed connector valve after step 5 due
to limited space.
5. Using the flat and cone washers as necessary, install the feed adapter into the faucet inlet
connector or angle stop valve as chosen above. Then reconnect the cold water feed line to the
open end of the feed adapter. Tighten all connections securely.
6. Using the green tubing, install the brass nut, then the plastic ferrule and plastic tube insert.
Secure the tubing into the feed connector valve. Tighten the tubing retaining nut securely. See
Fig. 2.
7. Obtain the small feed valve warning tag from
the parts bag and attach it by its wire ties to the
feed valve.
