Maintenance Tip

• Clean exterior daily: Wipe stainless steel top and black vinyl body to remove spills, condensation, and sticky bar residue for a clean workspace.
• Clean condenser coils regularly: Remove dust and grease buildup to maintain efficient cooling and reduce compressor strain.
• Maintain door gaskets: Inspect and clean seals weekly to ensure tight closure and prevent cold air loss.
• Monitor temperature daily (36–38°F): Keep both thermostats within range for safe beverage storage and consistent performance.
• Keep front ventilation clear: Ensure airflow is not blocked since the unit is front-vented for efficient heat exchange.
• Defrost and clear drain system: Prevent ice or water buildup and ensure condensate evaporator is functioning properly.
• Avoid overloading shelves/keg zones: Maintain proper airflow inside each section for even cooling distribution.
• Deep clean monthly: Empty compartments and sanitize interior stainless steel surfaces, shelves, and floor.
• Check electrical connection: Ensure plug, cord, and outlet remain dry, secure, and undamaged for safe operation.
