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 O.

IMPORTANT: 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 installations 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 the hardware from the threaded nipple of the faucet, except for the chrome base plate and the rubber washer. The rubber washer may be replaced with a bead of plumber's putty for a neater appearance.

3)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.

4)Connect the 3/8" black tubing to the larger 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 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.
