Step 15 Gather the pieces of the drain saddle (#30)
1 Black compression nut
1 Semi-circle bracket with opening
2 Screws
1 Foam washer/gasket
2 Nuts for screws
1 Semi-circle bracket
Step 16
The small square black foam gasket with a circle cut out of the mid-
dle must be applied to the inside of the drain saddle. Remove sticky
tape backing and stick to the drain saddle as shown.
Step 17
Drill a 1/4” hole through the drain pipe at least 1 1/2” above the nut
of the P-trap to allow for the removal of the P-trap, if necessary.
Assemble the drain saddle around the drain pipe. Position the drain
saddle over the drilled hole in pipe. Insert screw driver into pipe.
Using Phillips screw driver, tighten screws evenly and securely on
both sides of the drain saddle. Attach black compression nut, but do
not tighten at this time. The black tubing will be installed later.
CAUTION:
Do not over tighten the screws. It may crack the drain saddle.

Shut-off Valve
Tubing Connections
Note: Do not cut tubes until you get to those steps. Remove caps, if any, from tubes before
cutting tubes. Use wire cutters or sharp knife to make straight square cut. Do not use scis-
sors.
Clear Tube Connection
Step 20
Cut 4"-6" from the clear ¼" tubing. Insert the end of this small sec
tion of tubing into the shut-off valve previously connected to the tank.
Insert the other end of the tubing into the middle port of the ¼" x ¼"
x ¼" tee connector (MC445).
20a The tubing must be fully inserted in the connector fitting; it is recom-
mended that you measure and mark the end of the tubing that you are
inserting in the fitting to assure that it is inserted as far as it will go.
The 1/4” tubing should be inserted about 5/8”. Push the tubing
through the small hole in the connector 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.
Instructions for installing the
remaining clear tubing can be
found on page 10, step 32.
