SADDLE-TAPPING VALVE INSTALLATION ON COPPER TUBE
CAUTION: This saddle-tapping valve is not designed for installation on flex line tubing.
NOTE: For installation in Massachusetts, the Massachusetts Plumbing Code 248 CMR shall be adhered to. Consult your licensed plumber for
installation of this system. The use of saddle (piercing) valves is not permitted.
1. CAUTION: if no shut off valve is installed under sink, close main
water valve during this installation.
locate shut off valves on water lines under sink. To identify hot
supply pipe and cold supply pipe, turn both faucets on and let
water run. As water flows, hot water pipe becomes noticeably
warmer.
2. CAUTION: do not install feed water assembly on hot water line.
Turn off cold water supply by closing shut off valve. drain line by
opening sink faucet. Some mixing type faucets may require hot
water supply be shut off as well.
NOTE: All instructions refer to components shown in Figure 3
unless otherwise noted.
3. CAUTION: do not turn valve handle before or while installing
saddle-tapping valve. Make sure piercing lance does not pro-
trude beyond rubber gasket before installing valve.
Assemble saddle-tapping valve assembly on tube.
a. Hold back plate against tube.
• 3/8” copper tubing use back plate smaller radius.
• 1/2” copper tubing, use back plate larger radius
b. Hold valve saddle against tubing in a position directly
opposite back plate.
c. Tighten screw enough so valve saddle and back plate are
held securely against tube.
d. rotate assembly so tubing connection is aligned toward ro
Module feed port.
e. Tighten screw firmly. Do not crush tube.
4. Connect source water feed tubing to valve body using compres-
sion fitting.
a. Slide nut and sleeve onto tubing (in that order).
b. install insert into plastic tubing.
c. install tube with insert and sleeve into valve body.
d. Thread compression nut onto valve body, tighten.
5. Turn saddle-tapping valve handle clockwise until it is
firmly seated and piercing lance is fully extended.
6. CAUTION: Supply line is pierced and valve is closed.
do not open valve until system is activated (Page 9).
Turn on cold water supply. Check saddle-tapping valve installa-
tion for leaks. Allow water to run from faucet for a few minutes to
clear any debris in the line caused by installation.
NOTE: if flow from sink faucet is reduced, clean faucet aerator.

7. Trim ¼” white tube to desired length. Install ¼” white tube into ¼”
white collet as shown in Figure 1.A.
ADDITIONAL POINT OF USE CONNECTION
NOTE: Icemakers typically use 1/4” tubing as feed line. Use a reducing union (P/N 92402) for this connection.
NOTE: Reduce the 3/8” Line to 1/4” as close as possible to the additional point-of use device to minimize flow loss.
1. To connect an additional point of use (icemaker, extra faucet
in wet bar and/or another use for treated water), place a “tee”
connector (P/N 92403) in 3/8” blue line between faucet and RO
Module.
2. Connect “tee” to point-of-use with 3/8” blue tubing (P/N 87600).
Connect tubing to point-of-use. Connector requirements are
based on type of delivery device i.e., a typical icemaker uses
3/8” x 1/4” reducing device.
