Maintenance Tips

• Daily cleaning: Wipe stainless steel surfaces with mild detergent; avoid chlorine, abrasives, and harsh chemicals to prevent corrosion.
• No water use: Do not add water to wells—Halo Heat is a dry system; water can damage components and reduce performance.
• Keep divider bars in place: Ensure all gaps between pans are sealed to maintain even heat distribution and efficiency.
• Preheat properly: Run at full setting (~10) for at least 30 minutes before loading food for stable holding temperatures.
• Monitor food temps: Regularly verify safe holding range (140°F–180°F / 60°C–82°C) using a probe thermometer.
• Inspect controls: Check thermostats and indicator lights periodically for accuracy and responsiveness.
• Avoid steam cleaning: Never hose down or flood the unit; moisture can cause electrical damage and void warranty.
• Routine servicing: Schedule periodic professional inspection to maintain energy efficiency and heating consistency.
