Maintenance Tips

• Daily dry cleaning: Wipe stainless steel wells and exterior after service to remove food residue and maintain hygiene.
• Waterless operation only: Halo Heat® is fully dry—never add water or steam; prevents scale, corrosion, and plumbing issues.
• Use mild, non-abrasive cleaners: Protect stainless steel finish; avoid chlorine-based or harsh scrubbing agents.
• Avoid flooding or hosing: Never steam clean or spray with water to prevent electrical damage and safety hazards.
• Keep wells debris-free: Remove grease and spills promptly to maintain even radiant heat performance.
• Check thermostats regularly: Ensure independent controls maintain accurate holding temperatures for food safety.
• Preheat before use: Run unit before loading food to stabilize heat distribution and performance.
• Inspect electrical components: Periodically check wiring, controls, and connections for safe operation.
• Use divider bars correctly: Keep pan gaps sealed for even heat distribution and consistent holding.
