5. Operating Instructions
Once the device is set up, follow these steps for proper operation.
- Connect to Power: Plug the power cord into a standard electrical outlet (AC 230V/50Hz).
- Start Nebulisation: Flip the power switch on the compressor unit to the 'ON' position. The unit will start, and a fine mist should begin to emerge from the mouthpiece or mask.
- Inhale Medication: If using the mouthpiece, place it between your teeth and seal your lips around it. If using a mask, place it over your nose and mouth, ensuring a snug fit. Breathe normally and deeply until the medication is fully nebulised (typically 5-15 minutes, or as advised by your doctor).
- End Treatment: Once the medication is depleted and mist production stops, turn the power switch to the 'OFF' position.
- Disconnect Power: Unplug the device from the electrical outlet.
Note: The device is designed for a maximum continuous operation time of 30 minutes. Allow a cool-down period if multiple treatments are required.
