Maintenance Tips
- Clean the glass/holding surface daily using a soft cloth and mild, non-abrasive cleaner after the unit has cooled.
- Wipe spills immediately to prevent burnt residue and reduced heat transfer efficiency.
- Keep all air intake vents, fans, and cooling channels free of grease, dust, and blockage to prevent overheating.
- Ensure proper clearance around the unit so airflow remains unobstructed during operation.
- Always power off and disconnect before cleaning or servicing.
- Use only induction-compatible cookware or approved holding pans for stable temperature control.
- Avoid abrasive pads, steel wool, or harsh chemicals that can damage the surface or controls.
- Do not operate with empty pans or dry zones, as this can trigger safety shutdown and stress components.
- Regularly inspect power cords, plugs, and connections for wear or damage in high-use environments.
- Schedule periodic professional servicing to maintain consistent performance, energy efficiency, and long equipment lifespan.
