-- STEP 1: INSTALL COLD WATER SUPPLY SADDLE VALVE --
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 saddle valve is shown in
FIG.3 - A
below. An optional connection, using standard plumb-
ing fittings (not included), is shown in
B.
Note: Codes in the state of Massachusetts require instal-
lation by a licensed plumber, and do not permit the use
of the saddle valve.
For installation, use plumbing
code 248- CMR of the Commonwealth of Massa-
chusetts.
A. SADDLE VALVE
Note:
This valve has a cutting pin and will pierce a
hole in copper tubing or plastic pipe. If installing on
iron pipe, you have to drill a 1/8”hole for the pierc-
ing pin.
Read the following danger note
and be
sure to
turn off water
to the pipe and to drain water
from it
before drilling.
DANGER
(if drilling metal pipe): To protect your-
self from serious injury or fatal shock, use a battery
powered hand drill only to make the hole. Do not
use an electric drill.
1.
Close the house main water shutoff valve and open
faucets to drain water from the sink cold water pipe.
2.
Observing above note and caution, drill the 1/8”
diameter hole in
iron
pipe.
3.
Looking at figure 3A, turn the valve into clamp X
and tighten (maybe already assembled). Turn the
valve handle all the way out.
4.
Place the seal on the inside of clamp X as shown.
Be sure the cutting pin does not stick out beyond the
seal.
5.
Place clamp X and Z around the pipe and secure in
place with 2 screws. If you predrilled a 1/8” hole,
align the cutting pin with it. Tighten both screws
evenly, but
do not overtighten
. Clamp Z will either
have threaded screw holes, or 2 nuts are included.
6.
Carefully turn the handle inward to pierce a hole
in the copper or plastic pipe.
B. OPTIONAL PIPE FITTINGS
(compression type
shown)
Note:
Be sure to turn off the 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.
A typical connection is shown in figure 3B. If
threaded fittings are used, be sure to use pipe joint
compound or Teflon tape on outside threads.
