Understanding High-Speed Permanent-Magnet Motor Technology
The included WasteGuard disposal relies on a permanent-magnet motor that spins at an impressive 3800 RPM. Think of it like a sports car engine compared to a standard sedan; instead of building up momentum slowly like traditional induction motors, it delivers instant torque right at startup. This high rotational speed instantly pulverizes food scraps into fine particles, reducing the chance of plumbing clogs and ensuring fast, reliable performance every time you flip the wall switch.
Installation Guide
Verify your cabinet base measures at least 36 inches wide and check that your under-sink clearance accommodates the 15 1/4 inch disposal height.
Choose between top mount installation or undermount installation based on your countertop material and aesthetic preference.
Utilize the EZLock 2-step mounting assembly to secure the garbage disposal flange easily into standard 3 1/2 inch drain openings.
Connect the disposal to standard 1 1/2 inch kitchen plumbing connections and plug in the included power cord.
Care & Maintenance
Daily Cleaning: Wipe down the granite composite surface regularly with warm soapy water and a soft cloth to prevent water spot buildup.
Stain Prevention: Rinse the sink thoroughly after washing coffee, tea, or dark liquids to maintain the deep black onyx finish.
Avoid Harsh Chemicals: Refrain from using abrasive scouring pads, steel wool, or harsh bleach-based cleaners on the stone surface.
Disposal Freshness: Run cold water through the garbage disposal while grinding citrus peels occasionally to naturally clean the grinding chamber.
Prevent Blockages: Avoid putting fibrous vegetables, grease, or large bones down the disposal to protect the 3/4 horsepower motor.
