Q&A

Maintenance Tips

• Daily cleaning: Wipe stainless steel top, doors, and handles with food-safe sanitizer to prevent spills, stains, and contamination.
• Maintain airflow (critical): Keep front ventilation intake/exhaust clear to ensure proper cooling and prevent compressor overheating.
• Temperature control: Monitor digital thermostat regularly; maintain stable range ~36–38°F (2–3°C) for safe beverage storage.
• Door gasket inspection: Clean seals weekly and replace if worn to avoid cold air leaks and energy loss.
• Interior sanitation: Weekly wipe-down of stainless steel interior walls and floor to prevent mold, odors, and residue buildup.
• Condenser cleaning: Remove dust and grease periodically to maintain cooling efficiency and extend compressor life.
• Drain/evaporator check: Ensure automatic condensate system is clear and functioning to prevent moisture buildup.
• Load management: Do not overpack shelves; maintain airflow gaps for even cooling distribution.
• Electrical check: Inspect plug, cord, and connections for wear or overheating signs.
