Understanding the Power of Permanent-Magnet Motor Technology
Traditional garbage disposals often rely on induction motors that take time to reach peak velocity, which can lead to jams when heavy food scraps are introduced. The Kraus WasteGuard included in this bundle utilizes an advanced permanent-magnet motor that spins at a staggering 3800 RPM the exact second you flip the switch. Think of it like a sports car engine versus a standard sedan; the permanent-magnet design delivers instant torque right off the line, allowing the grinding chamber to pulverize tough vegetable peels, fruit pits, and leftovers nearly instantaneously. Combined with a generous 40.6-ounce grinding chamber, this technology eliminates the need to feed waste in slow batches, making kitchen cleanup faster, safer, and remarkably efficient.
Installation Guide
Ensure your base cabinet measures at least 33 inches wide and provides adequate installation clearance for both the sink basin and the 15 1/4 inch tall disposal unit.
Secure the undermount sink to your solid surface countertop using compatible mounting brackets and silicone sealant for a watertight bond.
Attach the garbage disposal using the EZLock 2-step mounting assembly, which drops easily into place without requiring messy plumber's putty for most sinks.
Connect the standard 1 1/2 inch kitchen plumbing lines and plug the disposal power cord into a properly grounded electrical outlet.
Care & Maintenance
Daily Rinsing Rinse the sink thoroughly with warm water and a mild dish soap after each use to prevent residue buildup.
Routine Wiping Wipe the non-porous granite surface dry with a soft microfiber cloth to maintain its smooth texture and rich color.
Stain Prevention Avoid leaving standing liquids or harsh chemical cleaners on the stone surface for extended periods.
Periodic Deep Cleaning Use a non-abrasive cleaner formulated for granite composite to lift stubborn spots without scratching the finish.
Disposal Maintenance Run cold water through the disposal during operation and grind small ice cubes occasionally to help clean the internal grinding components.
