Here is a url to the Aeternum website:

There is some information on how to use it. I don't have one but do know that the elliptical lid has to be sort of dipped underneath the its' rim and then rotated and locked into place with the lever. Make sure that the gasket, lid & rim of the pot are clean and seated in place when you close it. I would practice several times before trying it out on the stove.

Your unit should have two valves. One will allow air & steam to vent for period of time while the liquid inside the cooker is heating up. After a few minutes it will automatically close and pressure will begin to build up inside. That 2nd valve does a lot to reduce or eliminate the problem of foaming that sometimes occurs when cooking foods such as rice. After top pressure is reached turn the heat down to about 1/3 of maximum. If that is not enough to keep it at top pressure turn the heat up a little at a time to find out the minimum heat setting to maintain high pressure. Conversely, you may need to turn it down a little if a lot of steam is escaping from the cooker.

As far as precautions to take, I would try it first with water only. Add water until it is about 1/3 full and close the lid. Next put it on a burner at turn it to high. As the water heats up you will notice that the small valve will allow air & steam to escape for awhile.(as I mentioned above) When the small valve finally raises and seals the regulator valve will begin to operate. When full pressure is reached you will know by the increasin amount of steam which begins to escape. When that occurs it's time to turn the heat lower to reach a state where just a little steam escapes. From there watch what happens when you turn off the heat. Things will quiet down and pressure will gradually release. When the small valve finally releases it will be safe to open the unit. I suggest observing how the 2nd valve works by taking the pressure cooker while it is at the highest pressure and run it under a small stream of cool tap water. The pressure inside will reduce to a point where the small valve will release and suck air into the pot. That is the surest sign that it is safe to open the unit with the lever. I suggest doing a few practice runs this way to get familiar with it before you cook any food. Good luck.
