Maintenance Tips

• Daily cleaning: Wipe stainless steel wells, flange, and exterior after cooling to remove grease and food residue for hygienic operation.
• Waterless Halo Heat system: Operates dry with no water, steam, or plumbing required, eliminating scale buildup and simplifying maintenance.
• Immediate spill removal: Clean spills quickly since there is no drain system—prevents odor, staining, and hardened residue.
• Thermostat control check: Verify both independent controls regularly to maintain stable, consistent holding temperatures.
• Use divider bars properly: Keep pan dividers installed for even heat distribution and flexible food configurations.
• Keep ventilation clear: Maintain open airflow around the unit to support efficient radiant heat performance.
• Avoid harsh chemicals: Use mild detergent only to protect stainless steel and preserve finish quality.
• Inspect electrical components: Check cords, plugs, and controls regularly to ensure safe, uninterrupted operation.
• Prevent buildup zones: Focus cleaning on corners, edges, and pan rails where residue accumulates fastest.
• Routine servicing: Schedule preventive maintenance to ensure long-term heating accuracy and equipment reliability.
