Placement Tips
- Place machines low (floor level) for ground-hugging fog.
- Aim toward the center of the room for even distribution.
- A single machine against one wall works for smaller spaces.
- Avoid pointing directly at smoke detectors — check your alarm type first.
- Keep ventilation in mind; crack a window if fog becomes too thick.
