heck and comply with local plumbing codes as you plan,
then install a cold feed (supply) water fitting. Refer to the
S
pecifications 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 7.
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.
NOTE: Codes in the state of Massachusetts require
installation by a licensed plumber and do not permit
the use of saddle valves.
If you live in the state of Massachusetts, review plumb-
ing 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 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 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 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.
