1. Unpack carefully your generator. Make sure that there is no visible damage due to transportation. If there is any damage, please take pictures and contact Altitude Training before using the generator. 2. Remove the safety strap located under the generator. If you’re planning to travel with your generator, you can leave the strap on, as it can not be placed again once removed. 3. On the oxygen port, plug the long clear tube supplied. 4. On the other end of the tube, plug the «Y» piece. On one of the side, insert the 3L balloon. On the other side, insert one grey tube. 5. Place the green filter at the other end of the last grey tube, and insert the second grey tube on the green filter. This last tube has to be inserted into one of the small side opening of the tent. 6. Place the generator in a dry and cold room for maximum effeciency. Make sure the generator has access to enough fresh air in the room. 7. Turn on the generator with the general black switch, and then with the ON/OFF button under the screen. Check the Altitude Chart on the back of the generator to set the correct altitude. 8. Use the GEAR (black valve at the front) and the FLOW (ball in the cylinder) to set your altitude. 9. Turn off the generator when not using.
