Maintenance Tips    

• Daily cleaning: Wipe stainless steel wells and exterior with mild detergent; avoid chlorine, bleach, or abrasive pads to protect finish and prevent corrosion.
• Dry operation only: Never add water—this Halo Heat system is designed for dry heat holding, which reduces scale buildup and maintenance needs.
• Remove food debris promptly: Clean spills and residue after each service to prevent buildup and maintain hygiene.
• Check controls regularly: Inspect thermostats, indicator lights, and control settings for accuracy and consistent holding temperatures.
• Keep vents and controls clear: Ensure airflow areas are free from grease and dust for stable heat performance.
• Avoid pressure washing: Never hose down the unit—moisture can damage electrical components.
• Inspect divider bars & pan fit: Ensure proper placement for even heat distribution across wells.
• Routine professional servicing: Schedule periodic checks to maintain energy efficiency and long-term reliability.
