4. Setup (Installation)

The Kohler K-3362-4-NA is a top-mount (drop-in) sink. Follow these steps for proper installation:

1. Prepare the Countertop: Place the provided installation template on your countertop. Ensure proper alignment and clearance from cabinets and walls. Trace the cutout line onto the countertop. Carefully cut the opening using appropriate tools, following the traced line.
2. Apply Sealant: Apply a continuous bead of silicone sealant or plumber's putty around the perimeter of the cutout opening on the countertop. This creates a watertight seal between the sink and the countertop.
3. Position the Sink: Carefully lower the sink into the cutout opening. Ensure the sink rim is evenly seated on the sealant. Apply gentle downward pressure to ensure good contact.
4. Secure Mounting Clips: From underneath the countertop, attach the provided mounting clips to the sink rim. Tighten the screws on the clips evenly around the sink perimeter to secure the sink firmly in place. Do not overtighten.
5. Connect Plumbing: Install the drain assembly (not included) into the sink drain opening according to its manufacturer's instructions. Connect the faucet and other accessories (e.g., soap dispenser, side spray) to the four pre-drilled holes on the sink deck. Connect water supply lines and drain pipes to the installed fixtures.
6. Test for Leaks: Turn on the main water supply. Run water into the sink and check all plumbing connections (drain, faucet, supply lines) for any leaks. Tighten any connections as necessary. Wipe away any excess sealant from the sink rim.

5. Operating (Usage)

The Kohler K-3362-4-NA sink is designed for general kitchen use, including washing dishes, preparing food, and other household tasks. Ensure proper drainage by keeping the drain clear of debris. The four pre-drilled holes accommodate a variety of faucet and accessory configurations.

6. Maintenance and Care

Proper care will help maintain the appearance and extend the life of your stainless steel sink:

• Daily Cleaning: After each use, rinse the sink thoroughly with water to remove food particles and soap residue. Wipe with a soft, dry cloth to prevent water spots and maintain the stainless steel finish.
• Stubborn Stains: For more stubborn stains, use a mild, non-abrasive cleaner specifically designed for stainless steel. Always rub in the direction of the grain. Rinse thoroughly and dry immediately.
• Avoid: Do not use abrasive cleaners, steel wool, scouring pads, or harsh chemicals (e.g., bleach, ammonia-based cleaners) as these can scratch or damage the stainless steel finish. Avoid leaving acidic foods or liquids (e.g., citrus juices, vinegar) in the sink for extended periods, as they can cause discoloration.
• Prevent Scratches: While stainless steel is durable, it can scratch. Use a sink grid (sold separately) to protect the basin bottom from heavy pots and pans.

7. Troubleshooting

Here are solutions to common issues you might encounter:

• Slow Drainage: Check the drain for food particles or debris. Use a plunger or a drain snake if necessary to clear blockages. Avoid pouring grease down the drain, as it can solidify and cause clogs.
• Leaks Around Drain or Faucet: Check all plumbing connections for tightness. If leaks persist, the sealant or washers may need replacement. Consult a plumber if you are unable to resolve the issue.
• Water Spots or Streaks: These are common, especially with hard water. Wipe the sink dry after each use. For existing spots, use a stainless steel cleaner or a solution of equal parts white vinegar and water, then rinse thoroughly and dry.
• Rust Spots: Stainless steel is resistant to rust, but rust spots can occur if ferrous materials (e.g., cast iron pans, steel wool fragments) are left in contact with the sink surface for extended periods. Remove rust spots with a non-abrasive stainless steel cleaner and prevent recurrence by removing foreign objects promptly.
