Maintenance

Regular maintenance ensures optimal performance and longevity of your Unistar DF268 cooler.

• General Cleaning: Wipe the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.

• Storage: When storing the unit, ensure the water tank is empty and clean, and the filters are dry. Store in a cool, dry place.

Troubleshooting
