Maintenance
Proper maintenance ensures the longevity and optimal performance of your fog machine.
- Cleaning: After every 40 hours of continuous operation, or if the machine shows signs of reduced output, it is recommended to run a cleaning solution through the system. Use a commercially available fog machine cleaning solution or a mixture of 80% distilled water and 20% white vinegar. Run this solution through the machine for 10-15 minutes in a well-ventilated area.
- Exterior Cleaning: Wipe the exterior of the machine with a soft, dry cloth. Do not use abrasive cleaners or allow liquids to enter internal components.
- Storage: When not in use, ensure the machine is completely cool and drained of any remaining fog fluid. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Fuse Replacement: If the machine does not power on, check the fuse located near the power socket. Replace with a fuse of the same type and rating if necessary.
