Locate mounting hardware (refer to figures on opposite side). This will consist of six items; a black rubber gasket, mounting washer, spacer (use if needed), flat washer, lock washer and a mounting nut. With black rubber gasket in hand, feed tubing from faucet through rubber gasket. Align rubber gasket with bottom of base. Next, add remaining 5 parts to the threaded copper tube loosely (do not tighten). Parts are to be assembled in the same order listed above, except for mounting washer, set this aside (do not discard). Next, feed all tubes and mounting hardware into the mounting hole in sink using care, as there may be sharp edges if a new hole has been made. With faucet base and gasket seated over mounting hole, take the mounting washer and slide it between mounting surface and spacer (if spacer is not being used, slide between flat washer and mounting surface) keeping in line with threaded copper tube. Tighten mounting nut so that faucet barely moves against mounting surface, adjust faucet to desired orientation on sink. Tighten mounting nut, do not over tighten. With faucet in place and tight, plumbing connections can be completed.
