Installation Steps and Start-Up Procedures, Cont.

Step 4

Prepare the RO Air Gap Spigot Assembly for Installation
A. Using the diagram in Figure 6, assemble the Air Gap Spigot with all the components except
the slot washer. Begin with the escutcheon, followed by the rubber gasket, spacer, flat
washer, 9/16-inch nut, and 3/8-inch spigot adapter.
B. Using the diagram in Figure 2, from under the sink, feed the pre-connected 1/4-inch black
tube and the pre-connected 3/8-inch blue tube from the RO assembly through the hole in the
sink. Remove the red locking clip from the spigot adapter, slip the blue tube into the spigot
adapter, and replace the red locking clip. Slip the 1/4-inch black tube onto the small hose
barb on the base of the spigot.
C. Slip one end of the loose 3/8-inch black tube over the large hose barb on the base of the
spigot.
Installation Tip: To make it easier to slip the tubing over the hose barbs, soak the black tube
ends in hot water to soften the tubing. The tubing will slip onto the hose barbs much more easily,
and will conform better as it cools and reduce the possibility of splitting.
D. Feed the assembled spigot and tubing through the hole in the sink and let the spigot rest on
the rubber gasket and escutcheon.
E. From under the sink, slip the slot washer between the sink and the spacer and finger-tighten
the 9/16-inch nut until snug.
F. Position the spigot for customer convenience and then use a 9/16-inch wrench to tighten the
nut to secure the spigot on the sink.
