Check and comply with local plumbing codes as you plan,
then install a cold feed (supply) water fitting. Refer to the
Specifications page for supply water requirements. The fit-
ting must provide a leak-tight connection to the RO 1/4" tub-
ing. A typical connection using the included water supply fit-
ting is shown in Figure 6.. An optional connection using
standard plumbing fittings (not included) is shown in Figure
6B.
NOTE: Local code may dictate which type of water fit-
ting is used. Consult a plumber if you are not familiar
with local codes or plumbing procedures.
INSTALL COLD WATER SUPPLY FITTING
(Included with your package)
This fitting will be installed on the cold water pipe. The fit-
ting must provide a leak-tight connection to the Reverse
Osmosis 1/4" tubing. Locate the cold water line in the sink
cabinet. It is recommended, but not required, that the cold
water line be soft water..
Complete the following steps to install the water supply fit-
ting.
1
. Close the water shut off valve that is immediately before
supply fitting and open faucets to drain water from the
sink cold water pipe.
2
. Remove nut that connects the cold water faucet to cold
water plumbing.
3
. Thread water supply fitting onto pipe and reconnect nut
to bottom of fitting.
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 1/4" OD tubing. A typical connection is
shown in Figure 6B. If threaded fittings are used, be sure to
use pipe joint compound or thread sealing tape on outside
threads.
