Reassembly

Fully insert the cartridge until the top of the cartridge ears are level with the top of the faucet body. Position the cartridge ears up and down to allow insertion of the retainer clip. The notched flat on the stem must point UP when mounting Knob or Concentrix Handles, DOWN for Lever Handle models. Replace the retainer clip (for lever handles replace spacer, grooved sleeve, retainer clip, and clip retainer ring) so that the legs straddle the cartridge ears and slide down into the bottom slot in the body. This prevents the cartridge from rotating and locks it in the body. Reinstall handle parts. Tighten handle screw securely. Press on handle cover. For Concentrix models install handle insert onto adapter (align locator notch on handle insert with key on adapter). NOTE: Locator notch on the handle insert must be on the bottom. Fit gasket up into handle cover recess. Replace handle cover and hand tighten.

Cleaning & Care Instructions for

Special Finish Models:

All that is necessary to clean these faucets is to wipe them with a soft, damp cloth such as terrycloth. Warm water will remove dry water spots. CAUTION: DO NOT use cleansers which contain abrasives or harsh chemicals. NEVER use alcohol or other organic solvents. A high quality, non abrasive wax polish applied occasionally will help to preserve the deep tones of the finish.
