DRAIN SADDLE INSTALLATION
1. Refer to Figure 2 and determine the location for the drain saddle assembly and drain
hole. It must be located above the “P” trap (“U” shaped bend in drain pipe) on the sink
side of the drain pipe.
2. Place the half of the drain saddle with threaded nipple at a predetermined location.
Slide a pencil through the plastic nipple and make a mark on the drain pipe.
3. Use a small punch and indent a start position to prevent the drill bit from wandering.
4. Drill a 3/8" hole in the drain pipe through the mark
on one side only,
do not drill
through both sides of the drain pipe. Clean any loose shavings from around the hole.
5. Refer to diagram below showing the drain saddle assembly sequence. Press nuts in
back half of drain saddle assembly.
6. Align the front half of the drain saddle by inserting a pencil through the plastic nipple
and the newly drilled hole in the drain pipe.
7. Install the back half of the drain saddle and clamp assembly to drain pipe by screwing in
the mounting bolts until snug.
WASTE WATER LINE INSTALLATION
(See Drinking Water Systems Plumbing Connections on Pages 6-8.)
NOTE: The tubing must be as SHORT and STRAIGHT as possible to allow for proper drainage and reduce the noise of
the Air Gap faucet.
1. Measure from the waste tube on the faucet to the drain saddle and make a straight cut with a sharp knife (DWS-90
and DWS-PP-90). For MPDW-90, the tubing will run from the union fitting at the end of the Red tubing connected
to the waste water port on the membrane housing to the drain saddle.
2. Remove Nut from drain saddle. Slip the waste tube through the nut. Insert waste tube into the opening in the drain
saddle and tighten the nut securely.
3. This line is gravity fed. If there is any bend in the tube the waste water will not flow into the drain properly. Water
may back up and come out the Air Gap hole in the back of the faucet base (DWS-90 and DWS-PP-90).
