Elbow Tubing Installation
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.
Elbow-Tubing Assembly
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.
4. Push the tubing through the nut until it
bottoms out in the elbow.
5. Remove the adapter nut, then install the
o-ring on the tubing. Do not push the
backup or metal grab rings back on the
tubing when installing the o-ring on the
tubing.
6. Install the adapter nut on the elbow and
hand-tighten the nut.

NSTALLATION
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.
Caution
Do not apply a wrench to the nut—
the nut should be hand-tightened
only to prevent leakage.
