Heat the water up and let it reach a boil, while stirring periodically to prevent the lentils on the bottom from burning. Seal the lid on, turn down the heat, and cook for 9 minutes at 8 psi. After 9 minutes, take the pressure cooker off the heat and either let it cool naturally, or vent it depending on how much volume you are cooking. If you have a larger volume, the lentils can overcook while they cool naturally.
