Important Safety Information
WARNING: USE IN UNOCCUPIED SPACE ONLY.
- Ozone works by attacking biological material. Therefore, it is crucial to avoid breathing in ozone.
- Do not be in the room or area when the ozone generator is operating. Ensure all people and pets are removed from the working area before activation.
- After the machine completes its purification cycle, open doors and windows to ensure proper ventilation for at least 30 minutes before re-entering the treated space. Inhaling too much ozone can be harmful.
- It is strictly prohibited for children to operate this machine.
- When not in use for a long period, turn off the power and unplug the power cord.

Operating Instructions
The JOBYNA Ozone Generator features two primary operating modes: Air Mode and Water Mode.
Air Mode Operation
Air Mode is designed for purifying large spaces and removing strong odors.
- Activation: Ensure the unit is plugged in. Press the red "AIR ON" button to activate Air Mode. The corresponding indicator light will illuminate.
- Timer Setting: Use the "MINUTES" dial to set the desired operating time (0-120 minutes). For continuous operation, set the dial to "HOLD".
- Recommended Usage:
Area Size (sq.ft) Recommended Time (min) 500 10 1000 20 1600 30 2100 60 2500 80 3200 100 3700 120 >3700 Hold - Important Note: For optimal results and to prevent over-ozonation, it is often more effective to use shorter periods of operation multiple times rather than one continuous long period.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | Blown fuse or power adapter issue. | Replace the fuse (refer to Maintenance section) or check the power adapter connection. |
| Lingering ozone smell after purification. | Ozone has permeated into materials. | Ensure adequate ventilation. Continue to ventilate the area until the smell dissipates. This may take some time. |
| Ineffective purification. | Incorrect operating time or mode; large area for chosen mode. | Refer to the "Operating Instructions" section for recommended times and modes based on area size or water volume. Consider using shorter, multiple cycles. |
