Installation
4. Thread the 1/8" NPT x 1/4" OD straight connector provided (part no.
15451) into the brass bushing at the faucet opening and connect the
tubing between this connection and the plumbing service connection
marked “inlet” on the holder.
5. Ensure that the 1/8" NPT x 1/4" OD polypropylene elbow (part no.
15847) is threaded into the effluent connection at the top of the holder
and connect tubing between this connection and the point of
distribution. See Elbow-Tubing Assembly in this manual to ensure that
the connection is made properly to prevent leakage.
6. Connect the remaining tubing to the plumbing service connection
marked “drain” and extend the tubing into the sink to allow the holder
to be drained in an unrestricted manner.
Caution Do not restrict the tubing and run the tubing in an upward
direction from the top of the unit. Any restriction on the outlet can result
in a cartridge bursting and flooding.

Assembling the tubing and polypropylene elbow is accomplished as follows
to ensure against leakage.
1. Remove the adapter nut, being careful not to lose the o-ring, backup
ring, and stainless steel grab ring.
2. Remove the o-ring from the elbow.
3. Install the metal grab ring and backup ring in the adapter nut, and
install the nut on the elbow. Do not install the o-ring at this time.
