Step A - Install Cold Water Supply 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 7.
NOTE: Local code may dictate which type of water
fitting is used. Consult a plumber if you are not familiar with
local codes or plumbing procedures.
NOTE: Codes in the state of Massachusetts require installa-
tion by a licensed plumber and do not permit the use of sad-
dle valves.
If you live in the state of Massachusetts, review
plumbing code 248-CMR of the Commonwealth of
Massachusetts before proceeding with the installation.
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 water shutoff valve (angle stop valve) that the
water supply fitting will be installed on, 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 sure not to cross thread or
overtighten.
5. Connect the existing cold water line to the male threaded
portion of the water supply fitting and hand tighten. Be
sure 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 7. If threaded fittings are used, be sure to
use pipe joint compound or thread sealing tape on outside
threads.
