When starting the exercise, the Airofit PRO 2.0 requires a short offset (zeroing) of the pressure measurement. Do not breathe into the trainer during this process. Wait for instructions to begin the breathing exercise.
The Airofit PRO 2.0 Breathing Trainer should not be used in conjunction with other physical activities. Breathing training during other physical exercises will compromise the oxygenation of the muscles involved in movement.
5 Maintenance
Always ensure your device is dry before storing it. It is recommended to store your Airofit PRO 2.0 in a suitable, clean, and hygienic manner. Fully charge your device if you do not use it for more than a week to prevent the battery from draining completely. Remember to fully charge the Airofit PRO 2.0 Breathing Trainer before using it again. (YouTube: Airofit PRO – Care and Maintenance)
Daily Maintenance
Since the device is exposed to saliva during use, it is important to clean it regularly. It is recommended to clean your device after each training session. Always remove the E-Unit before cleaning the device. Do not immerse the E-Unit in water or expose the product to water jets or other liquids. It is recommended to wash the trainer unit and mouthpiece in warm water (below 60°C). Shake off excess water after washing and blow through the device to remove any remaining water. Ensure your device is completely dry before reassembling and storing it. Airofit is not autoclave or dishwasher safe.
Weekly Maintenance
Once a week, use a drop of dish soap in water to thoroughly wash your trainer unit and mouthpiece. After washing, hold the trainer unit under running water to allow it to rinse through. Shake off excess water, blow through the device, and dry with a clean towel. Allow it to air dry. Ensure the device is completely dry before reassembling it.
Monthly Maintenance
Fully charge your E-Unit at least once a month, even if you are not using it, to prevent the battery from draining.
6 Getting Started with Airofit PRO 2.0
When using Airofit for the first time
Before starting your training, the E-Unit must be fully charged until the light shows a continuous green. This initial charge may take up to 24 hours. While the E-Unit is charging, rinse the Trainer and Mouthpiece in warm water, wipe them with a clean cloth, and let them air dry. Once the E-Unit is fully charged and the Trainer Unit and Mouthpiece are completely dry, you can reassemble the Breathing Trainer. The E-Unit contains electronics; therefore, do not immerse the E-Unit in water or expose it to water jets or other liquids.
Registration Procedure
