Setup and Installation

Proper installation is crucial for the performance and longevity of your Underscore bath. This model is designed for undermount installation.

• Pre-Installation Check: Before beginning installation, inspect the bath for any damage. Ensure all necessary components, including the separately sold Kohler Clearflo slotted overflow bath drain (model K-7272 or K-7271), are available.
• Structural Support: The floor support under the bath must be capable of bearing a minimum load of 50 pounds per square foot. This ensures stability and safety once the bath is filled.
• Water Supply: Ensure your hot water supply system can provide at least 70 percent of the bath's capacity, which is approximately 56.7 gallons, to allow for adequate hot water filling.
• Drain Installation: The Kohler Clearflo slotted overflow drain is required for installation. This drain system is designed to increase soaking depth by approximately 2 inches and features a toe-tap style drain. It is installed on one of the ends of the tub. Follow the specific instructions provided with the drain kit for proper sealing and connection to your plumbing system.
• Placement: Position the bath according to your bathroom design and plumbing rough-ins. Ensure adequate clearance for maintenance and access to plumbing connections.
• Sealing: Apply appropriate sealants around the perimeter of the bath where it meets the countertop or tile surface to prevent water infiltration.

Refer to the detailed installation instructions provided with your specific bath and drain kit for comprehensive steps and safety guidelines.

Operating Instructions

Using your KOHLER Underscore bath is straightforward:

1. Filling the Bath: Ensure the toe-tap drain is in the closed position. Turn on the hot and cold water faucets to achieve your desired water temperature. Fill the bath to a comfortable level, ensuring the water does not exceed the overflow drain.
2. Draining the Bath: To drain the bath, simply press the toe-tap drain to open it. The water will flow out through the drain.
3. Soaking Depth: The compatible Kohler Clearflo slotted overflow drain allows for an increased soaking depth of approximately 17-1/8 inches, providing a more immersive bathing experience.

Maintenance and Care

To maintain the pristine appearance and extend the life of your acrylic bath, follow these care guidelines:

• Regular Cleaning: Clean the bath regularly with a soft sponge or cloth and a mild, non-abrasive liquid cleaner. Rinse thoroughly with warm water after cleaning.
• Avoid Abrasives: Do not use abrasive cleaners, scouring pads, steel wool, or harsh chemicals (such as acetone, paint thinner, or strong acids/bases) as these can damage the acrylic surface and its smooth finish.
• Stain Removal: For stubborn stains, a paste of baking soda and water can be gently applied and rinsed. For more severe stains, consult Kohler's recommended cleaning products for acrylic surfaces.
• Preventing Scratches: Avoid dropping sharp or heavy objects into the bath. Do not use the bath as a cutting surface.
• Water Spots: To prevent water spots, wipe the bath dry with a soft cloth after each use.

Troubleshooting

If you encounter issues with your Underscore bath, consider the following common solutions:

• Slow Drainage:
  • Check the toe-tap drain for any obstructions.
  • Ensure the drain assembly is correctly installed and sealed.
  • If the issue persists, a plumber may need to inspect the trap and drain lines for blockages.
• Water Leaks:
  • Inspect all plumbing connections for tightness.
  • Check the sealant around the bath's perimeter for cracks or gaps. Reapply sealant if necessary.
  • If the leak appears to be from the bath itself, contact customer support.
• Surface Discoloration/Dullness:
  • Ensure you are using only non-abrasive cleaners.
  • Hard water deposits can cause dullness; use a descaling cleaner safe for acrylic surfaces.
  • Avoid prolonged contact with harsh chemicals or dyes.
