Q&A

Maintenance Tips

• Clean condenser coil regularly: Remove dust and grease every 2–3 months to maintain efficient cooling and prevent compressor strain.
• Maintain stable temperature (36–38°F): Ensures optimal beer storage, freshness, and consistent draft performance.
• Ensure proper airflow: Keep rear ventilation clear and avoid placing unit in tight, non-ventilated spaces to prevent overheating.
• Sanitize interior stainless steel: Clean regularly with non-chloride, non-abrasive cleaners to prevent corrosion and odor buildup.
• Check drain system: Inspect condensate drain and evaporator pan to avoid water pooling or leakage issues.
• Inspect door gasket: Keep seals clean and tight to maintain insulation efficiency and reduce energy consumption.
• Monitor refrigeration system: Periodically check compressor operation and thermostat accuracy for stable cooling performance.
• Line cleaning (if tapped): Flush beer lines with approved cleaning solution to prevent yeast, bacteria, and biofilm buildup.
• CO₂ system check: Ensure regulator, gas lines, and fittings are leak-free and properly pressurized.
• Careful keg handling: Load and unload kegs gently to protect internal stainless floor and sliding surface.
• Routine professional service: Schedule periodic maintenance to extend lifespan and ensure consistent commercial performance.
