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.
