Maintenance Tips
- Clean stainless-steel wells daily with mild detergent; avoid abrasive pads to protect finish and heat performance.
- Wipe dry after each use to prevent grease buildup, staining, and bacterial growth.
- Remove food debris immediately to maintain consistent Halo Heat distribution across individual wells.
- Inspect thermostatic controls regularly to ensure accurate, independent temperature settings for each well.
- Check divider bars, seals, and pan supports for wear to maintain even heat and food stability.
- Keep ventilation openings and surrounding counter cutouts clear of grease and dust for proper airflow.
- Avoid chlorine, ammonia, or harsh acidic cleaners that can damage stainless steel surfaces.
- Do not use water-based steam cleaning—this is a waterless Halo Heat system, designed for dry operation.
- Schedule preventive servicing to maintain long-term EcoSmart efficiency, safety, and heating consistency.
