3/8” Black Tube Connection from Faucet
Measure the black tube from faucet to the black drain saddle and
make a straight cut through tube.
Remove black plastic nut from drain saddle. Slip black tube
through black nut. Insert black tube into the opening in the drain
saddle and hand tighten the black nut, and add 1/4 turn with a
wrench.
This is a gravity fed line, if there is any bend or dip in the
tube the rinse 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.
The tubing must be as SHORT and STRAIGHT as possible
to the drain saddle, making a downward slope from module
to drain saddle to allow for proper drainage.

How To Use the Quick Connect Fittings on the RO Module
To make a connection, the tube is simply pushed into the fitting. Place a piece of tape 1/2” from end
of tube to indicate how far the tube should be inserted. The unique patented John Guest® locking
system holds
Cut the tube square. It is essential that the outside diameter
be free of score marks and that burrs and sharp edges be
removed before inserting into fitting.
Fitting grips before it seals. Ensure tube is pushed into
the tube stop.
Push the tube into the fitting, to the tube stop. The collet
(gripper) has stainless steel teeth which hold the tube
firmly in position while the O-ring provides a permanent
leak proof seal.
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.
To disconnect, ensure the system is depressurized before
removing the tube. Push in collect squarely against face
of fitting. With the collet held in this position, the tube can
be removed. The fitting can then be reused.
