E. MOUNT THE FAUCET
Undercounter installations generally require that the
faucet’s built-in air gap be used. In basement installations,
the built-in air gap does not have to be used if one is provided
elsewhere on the drain line.
For Basement Installations Without An Air Gap Module
See Installation Instructions on page 11.
IMPORTANT NOTE
• The Uniform Plumbing Code dictates that there must be
an air gap between the RO reject line and the waste drain.
An optional non-air gap faucet, which requires a smaller
9/16” mounting hole, is available to make basement in-
stallations easier.
Undercounter Installation With An Air Gap Faucet:
1) Familiarize yourself with all of the components shown in
the air gap faucet diagram. (See Fig. 2)
2) Remove 3/8” tubing in front of the black faucet handle and
discard. Push faucet spout into where the 3/8” tubing was
just removed.
3) Slide the chrome base plate and rubber washer up the
threaded base of faucet.
4) Connect the 1/4” green tubing supplied in the installation kit
to the smaller barb on the air gap faucet. Push it on firmly
until it seats.
5) From above the sink counter-top, feed the air gap tubing
and the threaded nipple through the faucet mounting hole
and position the faucet spout over the sink.
6) From below the sink/countertop, install the white spacer
(open side toward the air gap tubing), flat washer, lock wash
er and hex nut onto the threaded nipple and tighten it by
hand.
7) Back off on the hex nut just enough to slide the slotted
washer (open side toward the air gap tubes) between the
white spacer and the underside of the sink/countertop.
8) After rechecking the faucet orientation, tighten the hex nut
with a 9/16” wrench until the faucet feels secure.
9) From above the sink, make any minor orientation corrections
by turning the faucet on its flats with a padded adjustable
wrench. Use care so as not to mar the chrome finish.
