Maintenance Tips
-
Daily exterior cleaning: Wipe stainless top, glass doors, and handles with food-safe sanitizer to prevent smudges, spills, and contamination buildup.

Maintain airflow (critical): Keep front ventilation grill clear at all times for proper cooling and compressor efficiency.
-
Temperature monitoring: Check digital thermostat regularly and maintain ~33–41°F (0.5–5°C) for optimal beverage storage.
-
Door gasket care: Clean and inspect seals weekly; replace if worn to prevent cold air loss and energy waste.
-
Glass door care: Use non-ammonia cleaner to avoid damaging seals and maintain clear product visibility.
-
Condenser cleaning: Remove dust/debris periodically to prevent overheating and reduce compressor strain.
-
Interior sanitation: Weekly wipe-down of stainless interior walls and floor to prevent mold, odors, and residue buildup.
