Maintenance Tips

• Daily cleaning: Wipe stainless wells, divider bars, and exterior after cooling to prevent grease buildup and maintain food-safe conditions.
• Waterless operation only: Halo Heat is a dry radiant system—never add water or steam, as it can damage components and is not required.
• Clean spills immediately: No drain system, so prompt wiping prevents staining, odor, and hardened residue buildup.
• Thermostat check: Regularly verify temperature settings to ensure consistent hot-holding performance across all wells.
• Use divider bars correctly: Always install all pan dividers to maintain even heat distribution and stable holding temperatures.
• Keep vents & surroundings clear: Ensure surrounding counter areas stay free of grease and debris for proper airflow and efficiency.
• Avoid harsh chemicals: Use mild detergents only to protect stainless steel and maintain long-term durability.
• Inspect electrical components: Check cords, plugs, and controls regularly to ensure safe and reliable daily operation.
• Prevent buildup zones: Focus cleaning on corners, edges, and pan rails where residue accumulates fastest.
• Schedule preventive servicing: Routine technician checks help maintain heating consistency and extend equipment lifespan.
