Black Tube Connection from Faucet
NOTE: The tubing must be as SHORT and STRAIGHT as possible, making
a downward slope from the faucet to drain saddle to allow for proper
drainage.
Step 22 Measure the black tube from faucet to the black drain saddle and
make a straight cut with a sharp knife through tube. Do not use
scissors.
Step 23 Remove black plastic nut from drain saddle. Slip black tube through
black nut. Insert black tube into the opening in the drain saddle and
tighten the black nut securely.
NOTE: This is a gravity fed line, if there is any bend in the tube, the rinse water will not flow into the
drain properly. Water will back up and come out the air gap hole in the side of the faucet base.
Red Tube Connection from Faucet
Step 24 Using the white plastic union (#16) in the parts bag, determine
where the red tubing from the faucet and the black tubing from
the RO membrane housing would join together comfortably. Using
a knife, cut the tubes leaving a straight cut on both tubes. Insert
both red tubes in either end of the white plastic union. Use a 5/8"
wrench to tighten both of the white plastic nuts securely.
Blue Tube Connection
Step 21 Position the tank in the desired location. Stand it upright or lay it
on its side (using the black plastic stand) (#31). Measure the blue
tube from the RO module over to the tank and cut to length. Insert
the blue tubing into either side of the ¼" x ¼" x ¼" tee connector
closest to the RO module.
21a 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.
Blue
NOTE: To connect the 1/4" Blue Tube from the faucet, and the 1/4" Clear
Tube from the tank, see MP750SI Final Filter Installation. Do not
connect the faucet tubing until you get to that step.
Faucet Tube Connection
For the Blue and Clear Faucet Tube Connection instructions follow the MP750SI Installation instructions.
