Appliance functions
This device complies with IEC 60601-1-11 standards and is designed for the treatment of respiratory disease and the prevention ofrespiratory tract infections. It canbe used in the treatment of respiratory tract conditions, such as colds, fever,bronchitis, asthma,  pneumonia, pulmonary mycosis and cardiopulmonary disease. The exact therapy to be administered must be prescribed by a medical practitioner.
This appliance is based on a technology that uses the oscillation of the piezoelectric crystal inside it to transform medicinal products for inhalation into micro droplets of liquid. These micro droplets are able to penetrate deep into the upper and lower airways, to  carry the active substances to the right places in a targeted manner.

CLEANING and MAINTENANCE

To guarantee correct device operation, it is important to ensure that the Cleaning operations described below are carried out carefully. Otherwise, the device might not dispense the medicinal product the next time it is used, or the medicinal product might  bedispensed,but very slowly andnot at theideal speed.

Remember to turn off the device after use.
Make sure the device is switched off after use.
After each use, discard the leftover medicinal product and remove the accessory from the main unit in order to clean it thoroughly .Dry the parts immediately after washing.
Do not stow away the main unit, medicinal product vessel or other accessories when wet or damp.
Observe the following hygiene instructions in order to avoid any health risks. The nebulizer and accessories are intended for multiple use. Please note that cleaning and hygienic reconditioning requirements differ according to the different areas of application.
Parts (child mask, adult mask and mouthpiece) in contact with human body should only be used by the same person to prevent cross infection.

Cleaning and sanitising the medicinal product reservoir

• Remove the mouthpiece and any accessories from the atomizer.
• Open the vessel and discard any leftover medicinal product.
• Pour a small amount of hot distilled water (30-60°C) into the vessel and close the lid.
• Press press and hold the on/off button for 5 seconds to start cleaning mode, the blue power indicator light will come on.
• Switch the device on in cleaning mode to nebulise the distilled water for 1-2 minutes in order to eliminate the residual medicinal product. The cleaning mode stops automatically after 3 minutes.
• Rinse the vessel and lid with distilled water. Carefully remove any excess water with a clean, soft cloth or leave the parts to dry naturally in a clean place.
• Use medical gauze or cotton buds for cleaning and disinfecting operations.
• Use medical gauze or cotton buds for cleaning and disinfecting operations.
• Do not rub with paper or other cloths, to avoid compromising the correct operation of the appliance.
• Do not clean using sharp objects or touch the mesh.
• Do not use household bleach or other aggressive substances to clean the device, only the solution indicated above is allowed.

Cleaning and sanitising the main unit

• Carefully clean the main unit using a 75% rubbing alcohol solution and remove any excess with a clean, softcloth.
• Clean the electrodes connecting the main unit and the medicinal product vessel using the procedure indicated above.
  Do not clean the main unit using volatile liquids such as petrol or diluents.
  Do not rinse the main unit or immerse it in any liquid.

Cleaning and sanitising the mouthpiece and masks

• Remove the medicine cup, mouthpiece or mask.
• Rinse the medicinecup, mouthpiece and mask with de-mineralised water alone for 2-3 minutes (water temperature ≤50 °C).
• Dry well using medical gauze.
• Immerse the mask and mouthpiece in a 75% rubbing alcohol solution for at least 3 minutes to disinfect them and leave to dry naturally.
• Store the appliance in the carry case provided, when not in use.

Notes

• The cleaning mode is very important and must be completed, otherwise the atomizer will be blocked and cannot be used normally.
• Do not put pressure on the mesh with brushes or similar, as this may easily puncture the mesh causing irreparable damage, and will void the warranty. The metal is very thin and can be punctured easily.
• If any traces of medical solutions or impurities remain on the metal contacts on the device and atomizer, use cotton buds to remove them.
• Clean accessories & Medicine cup
• Remove the medicine cup and accessories (child mask, adult mask or mouthpiece) from the nebulizer. Clean with purified water.
• Please be careful not to use fast charging adapter for charging! Due to the circuit board chip charging input is 0.3V-6V more than 6V will trigger the chip protection, the use of the recommended adapter to use is 5V output.
  –The atomizer has overcharge protection, overdischarge protection and overcurrent.
  –Overcharge protection is the battery voltage to 4.3V is the battery full state will automatically disconnect charging protection.
  –Over-discharge protection: is the battery discharge to 2.3V is the lowest power state, the battery is automatically disconnected protection.
  –Over-current: that is, the charging line should not exceed 3A output input current. Now on the market are 1A-2A more basic general purpose!
