INSTALLATION QUICK LOOK
Please follow 4 color tubing diagram to complete installation
CAUTION: When cutting supplied tubes, predeter-
mine the length by measuring the distance between
the components to be connected.
No tools are needed to connect 4 colored tubes.
HOW TO MAKE A CONNECTION
1. CUT THE TUBE SQUARE
Cut the tube square. It is essential that the outside diameter
be free from score marks and that burrs and sharp edges be
removed before inserting into tting. For soft thin walled plastic
tubing we recommend the use of a tube insert.
2. INSERT TUBE
Fitting grips before it seals. Ensure tube is pushed into the tube
stop.
3. PUSH UP TO TUBE STOP
Push the tube into the tting, to the tube stop. The collet
(gripper) has stainless steel teeth which hold the tube rmly in
position while the o-ring provides a permanent leak proof seal.
4. PULL TO CHECK SECURE
Pull on the tube to check that it is secure. It is a good practice to
test the system prior to leaving site and/or before use.
Disconnecting PUSH COLLET AND REMOVE TUBE
To disconnect, ensure the system is depressurized before
removing the tube. Push in collet squarely against face of tting.
With the collet held in this position, the tube can be removed.
The tting can then be re-used.
Installation needs to comply with State and local plumbing regulations.

Make sure the surroundings of the sink are cooled before mounting the faucet to
the sink after drilling and remove all sharp edges.
3)
4)
Determine desired location for the RO faucet on your sink and place a piece of
masking tape over where the hole is to be drilled. Mark the center of the hole on
the tape.
1)
Using a variable speed drill set on the slowest speed, drill a
1
/ 8 “ pilot hole through
both porcelain and metal casing of sink at the marked center of the desired location.
Use lubricating oil or liquid soap to keep the drill bit cool (If drill bit gets hot it may
cause the porcelain to crack or chip).
Using a 1 ¼” hole saw, proceed to drill the large hole. Keep drill speed on the
slowest speed and use lubricating oil or liquid soap to keep the hole saw cool during
cutting.
2)
Drill a ¼” pilot hole. Use a
1
/ 2 ” Hole Punch and an adjustable wrench to punch the
hole in the sink. Change to the 1 ¼” Hole Punch to enlarge the hole.
5)
The faucet can now be installed.
If mounting faucet to a Stainless Steel Sink you will need a 1/2” & 1 ¼” Hole
Punch. The faucet opening should be centered between the back splash
and the edge of the sink, ideally on the same side as the vertical drain pipe.
Note:
Note:
Most sinks are pre drilled with 1 ½” or 1 ¼” diameter hole that you can use for your RO faucet. (If you are
already using it for a sprayer or soap dispenser, see step 1)
Porcelain sinks are extremely hard and can crack or chip easily.
Use extreme caution when drilling. Watts accepts no responsibility for
damage resulting from the installation of faucet. Diamond tip bit recommended.

Drinking Feed Tube Connection
Non Air Gap Faucet
Locate the 3/8” threaded quick connect tting in
the parts bag. After the faucet has been mounted,
thread the tting on the to faucet stem. Connect the
3/8” blue feed tube to the 3/8” quick connect t-
ting on the faucet stem. The nal polishing lter is
clipped on to the top of the RO membrane
housing. Attached to the polishing lter is a 3/8”
quick connect elbow tting. Attach the open end of
the 3/8” blue tubing from the RO faucet to the 3/8”
quick connect elbow on the polishing lter.
With Non Air-Gap faucets this will be the only tube
connected to the RO faucet.
Air Gap Faucet
Follow the drinking feed tube connection instruc-
tions above. Connect the 1/4” drain tube from the
RO module up to the 1/4” tting on the RO faucet.
The 3/8” drain tube from the RO faucet will connect
to the 3/8” drain saddle.

DRAIN SADDLE INSTALLATION
1)
2)
3) The drain saddle must be mounted at least 1 ½” above the nut of the P-trap or cross bar
from the garbage disposal to insure proper drainage. Assemble the drain saddle around
the drain pipe at the best available location. Using Phillips screw driver tighten screws
evenly and securely on both sides of the drain saddle. Keep the plastic compression
nut off at this time.
The small square black foam gasket with a circle cut out of the middle must be applied
to the inside of the drain saddle. Remove sticky tape backing and stick to the drain
saddle as shown.
1 Black compression nut 1 Semicircle bracket with opening
2 Screws 1 Foam gasket
2 Nuts for screws 1 Semicircle bracket
Gather the pieces of the drain saddle
Caution: Do not over tighten the screws. It may crack the drain saddle.
If you have a garbage disposal, do not install the drain saddle near it. Installation
of the drain saddle must be either above the garbage disposal, or if a second sink
drain is available, install it above the cross bar on the second drain. Installation of
the drain saddle near a garbage disposal may cause the drain line to plug.
Caution:
Turn off the cold water supply to the faucet by turning the angle stop valve completely off.
Attach the adapt-a-valve as illustrated in the three photos above, choosing the conguration that ts your
plumbing.
