Step A - Install Supply Water Fitting

CHOOSE TYPE OF WATER FITTING TO INSTALL
Check and comply with local plumbing codes as you plan,
then install a cold water supply fitting. Refer to the
Specifications page for supply water requirements. The fitting
must provide a leak-tight connection to the RO 1/4" tubing. A
typical connection using the included water supply fitting 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)
This fitting will be installed on the cold water pipe. The fitting
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 fitting.
1. Close the hot and cold water shutoff valves under the sink
where the cold water supply fitting will be installed, 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 over-
tighten.
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 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.
