2. Installation Instructions
Professional installation is recommended for optimal results and to ensure proper sealing and functionality. Ensure all local plumbing codes are followed.
2.1. Before You Begin
- Inspect the Sink: Carefully unpackage and inspect the sink for any damage. Do not install a damaged sink.
- Verify Cabinet Size: Ensure your base cabinet meets the minimum size requirement of 33 inches for this 27-inch sink model.
- Gather Tools: You will need standard plumbing tools, silicone sealant, mounting clips (if not pre-attached), a drill, and a jigsaw for countertop cutout (if applicable).
- Read Instructions: Familiarize yourself with the entire installation process before starting.
2.2. Countertop Preparation and Sink Mounting
- Create Cutout: Using the provided template (if included) or precise measurements, mark and cut the opening in your countertop. Ensure edges are smooth.
- Apply Sealant: Apply a continuous bead of silicone sealant around the perimeter of the sink's flange that will contact the underside of the countertop.
- Position Sink: Carefully lift the sink and align it with the countertop cutout from below. Press firmly to ensure good contact with the sealant.
- Secure with Clips: Attach and tighten the mounting clips evenly around the sink's perimeter to secure it to the countertop. Do not overtighten.
- Wipe Excess Sealant: Immediately wipe away any excess sealant that squeezes out from around the sink with a damp cloth.

2.3. Connecting Plumbing
- Install Drain Assembly: Install the pop-up drain assembly into the sink's drain opening according to the manufacturer's instructions for the drain. Ensure a watertight seal.
- Connect P-Trap: Connect the P-trap to the drain assembly and the wall drain pipe. Hand-tighten connections first, then use a wrench for a secure fit.
- Connect Faucet (if applicable): If installing a new faucet, follow its specific instructions to mount it to the countertop and connect the water supply lines.
- Test for Leaks: Turn on the water supply and fill the sink. Check all connections for leaks. Tighten any leaking connections as needed.
3. Operating Your Sink
The Franke CUX11027 sink is designed for everyday kitchen use. Its deep single bowl accommodates large pots and pans, making dishwashing and food preparation efficient.
3.1. Drain Usage
The sink features a rear drain placement, which maximizes usable space within the sink bowl and under the cabinet. The pop-up drain type allows for easy opening and closing to retain or release water. Ensure the drain strainer is regularly cleared of food debris to prevent blockages and maintain optimal drainage.

4. Care and Maintenance
Proper care will preserve the satin finish and extend the life of your Franke stainless steel sink. Stainless steel is durable but requires regular cleaning to maintain its appearance.
4.1. Daily Cleaning
- Wipe with Dry Cloth: After each use, rinse the sink thoroughly and wipe it dry with a soft, clean cloth. This prevents water spots and mineral deposits, especially in hard water areas.
- Mild Soap and Water: For general cleaning, use a mild dish soap and warm water. Apply with a soft sponge or cloth, then rinse completely and dry.
4.2. Stain Removal
- For Stubborn Stains: Use a non-abrasive stainless steel cleaner or a paste of baking soda and water. Apply in the direction of the grain, then rinse thoroughly and dry.
- Avoid Harsh Chemicals: Do not use steel wool, abrasive scrubbers, bleach, or cleaners containing chlorides, as these can damage the stainless steel finish and cause rust.
- Rust Spots: If rust spots appear (often from external iron particles), remove them immediately with a non-abrasive stainless steel cleaner.
4.3. Avoiding Damage
- Prevent Scratches: While stainless steel is resilient, heavy or sharp objects can cause scratches. Use a sink grid to protect the bottom of the sink.
- Heat Protection: Avoid placing extremely hot pots or pans directly into the sink without protection, as extreme temperature changes can affect the finish over time.
- Chemical Exposure: Do not leave acidic foods (e.g., citrus juices, tomato products) or strong chemicals in contact with the sink surface for extended periods.
5. Troubleshooting
This section addresses common issues you might encounter with your kitchen sink.
| Issue | Possible Cause | Solution |
|---|---|---|
| Slow Drainage | Food debris or grease buildup in the drain or P-trap. | Clear the drain strainer. Use a plunger or a drain snake to remove blockages. Avoid pouring grease down the drain. |
| Water Spots/Stains | Hard water mineral deposits; not drying the sink after use. | Wipe the sink dry after each use. Use a stainless steel cleaner or a vinegar solution for mineral deposits, then rinse and dry. |
| Minor Scratches | Abrasive contact with metal objects. | Minor scratches are normal with stainless steel over time. Use a stainless steel scratch removal kit (follow product instructions carefully) or a fine abrasive pad in the direction of the grain. |
| Dull Finish | Lack of regular cleaning or buildup of residue. | Clean regularly with mild soap and water. Use a stainless steel polish to restore luster, applying in the direction of the grain. |
