Check and comply with local plumbing codes as you plan, then install a cold feed (supply) water fitting. The
fitting must provide a leak- tight connection to the RO 1/4" tubing (see FIG. 8, page 8). A typical connection
using the included water supply fitting is shown in FIG.3 - A below. An optional connection, using standard
plumbing fittings (not included), is shown in B.

faucets to drain water from the sink cold water pipe.

3. Use pipe joint compound or Teflon tape on cold water
faucet stud threads and on the male threads of the water
supply fitting that connect to the cold water pipe.
4. Thread water supply fitting onto pipe and reconnect
nut to bottom of fitting.
B. OPTIONAL PIPE FITTINGS (compression type

Note: Be sure to turn offthe water supply and open
a low faucet to drain the pipe.
Complying with plumbing codes, install a fitting on
the kitchen cold water pipe to adapt 1/4" OD tubing.
