Maintenance Tips
- Keep air filters and intake/exhaust areas clean to maintain airflow and prevent coil strain
- Inspect and clean condenser and evaporator coils periodically to avoid dust buildup and reduced efficiency
- Ensure condensate drain path is clear to prevent water leakage or overflow issues
- Check wall seal and mounting sleeve to avoid air leaks that can destabilize cellar temperature
- Maintain proper clearance around vents for heat exchange performance
- Verify temperature sensor function and controller calibration for stable wine storage conditions
- Avoid blocking internal airflow inside the cellar (shelving too close reduces efficiency)
- Schedule annual inspection of refrigerant system and electrical connections for long-term reliability
