If your residence has a cold water supply line that does not have a ½" slip joint nut, or the water supply line is 3/8" to ½"
in diameter you may use the Saddle Clamp to connect your Drinking Water System to the plumbing. If your cold water
supply line is smaller than 3/8" or larger than ½" in diameter, it is recommended that the installation be done by a profes-
sional plumber in accordance with established plumbing procedures. Drinking Water Systems shipped with a Saddle
Clamp Assembly:
Saddle Clamp (Back Plate, Washer, Front Plate, Bolts) (#12) - MC249
Shut-Off Valve with adapter (#11) - MC1875
3/8" polyethylene tubing, clear (#2) - MC232
(for corresponding numbers, see diagram on page 4)
1. Install on the cold water line only. You should have on hand a container to
catch any residual water in the pipes.
2. Shut off your water at the plumbing shut-off (angle stop) valve under your sink. If you do
not have an angle stop valve under your sink, then you will need to locate the water shut-
off valve where water enters your residence.
3. DO NOT DISCONNECT ANY EXISTING CONNECTIONS.
4. Find a smooth surface on the supply line pipe, and using the ¼" high speed steel drill
bit, drill a hole in one wall ONLY of the supply line pipe.
5. Connect the saddle clamp to the pipe:
a. Slide the black washer over the nipple (hole) in the front plate of the Saddle
Clamp.
b. Clamp the front plate and back plate around the pipe with the nipple aligned with
the hole you drilled in the pipe.
c. Using the slotted screwdriver, tighten the clamp around the pipe by turning the bolts
clockwise.
6. Connect the Shut-off Valve with adapter to the front plate of the Saddle Clamp by
turning clockwise. Using an 8" adjustable wrench, tighten securely, but DO NOT
OVERTIGHTEN.
7 Connect the clear 3/8” plastic tubing, shipped with the unit, to the Shut-off Valve by
inserting the tubing through the small hole in the shut-off valve as far as it will go.
a. Cut (square cut) the tip ends off the tubing using a sharp knife. Do not use scissors.
b. The tubing must be fully inserted in the opening of the shut-off valve. It is recom-
mended that you measure and mark the end of the tubing. The 3/8” clear tubing
should be inserted about 7/8”.
c. Push the tubing through the small hole in the valve until you feel resistance -- at this
point, the tubing is not fully inserted. Then push firmly until the tubing is inserted as
far as it will go.
8. Confirm that the Unit Shut-off Valve is in the OFF position by turning the handle clockwise
until it stops.
9. To connect the clear tubing to your your drinking water unit proceed to Section V.
Push the tubing into the small hole
as far as it will go. Pull to check
secure.
