Maintenance Tips
- Clean or replace air filters regularly to maintain strong airflow and cooling efficiency
- Keep intake and exhaust grilles free from dust, blockage, and exterior debris
- Clean evaporator and condenser coils periodically to prevent reduced cooling performance
- Ensure condensate overflow system and drain path are clear to prevent leaks and humidity issues
- Inspect wall sleeve and exterior seals to prevent warm air infiltration and temperature fluctuation
- Maintain proper clearance around the unit for efficient heat exchange and airflow
- Verify thermostat and humidity sensor calibration for stable wine cellar conditions
- Check electrical connections and plug integrity for safe continuous operation (120V)
- Clean exterior-rated grille to maintain airflow and weather resistance performance
