Please read the Safety section in this manual
before you begin.
Plug the vacuum pump into a standard 110-volt outlet. The vacuum
pump will begin to work.
Enter the chamber. Most people find that getting on all fours and
backing in is the easiest for the 32" model or sitting on the edge of the
mattress for the 38" model.
Close the brass dump valve and the chrome altitude adjustment
valve.
Slide the chamber door towards you by pulling on the bottom handle
aligning the door to the left or right until it is centered to the chamber
opening.
Grab the left and right handles on the door and pull the door
tightly against the chamber opening squeezing the gasket. The door will seal
within seconds as a vacuum is created inside the chamber.
Relax and watch the altimeter climb. Yawn or "chew gum" as you
ascend in altitude to equalize the pressure on your ears.
Open the CHROME altitude
adjustment valve to slow your ascent as desired. Control your altitude by
adjusting the airflow from the CHROME altitude valve to set your
chamber environment to the desired altitude. You can start your clock timer to
monitor your time "at altitude."
Relax, lay back and let your body acclimate. You can set the alarm
if needed.
When you want to get out of the chamber, slightly open the BRASS dump valve just enough to start your
descent. Keep an eye on your altimeter as you gradually descend in altitude.
Don't forget to yawn or "chew gum" to equalize the pressure on your ears. On
the decent you can also hold your nose and blow air pressure to your ears to
equalize the pressure on your ears.
If your ears do not clear and begin to cause discomfort, close the BRASS dump valve slightly to increase your
altitude. This will relieve the pressure in your ears. You can then start your
descent again.
As you descend in altitude you will have to open the BRASS dump valve more and more to allow the greater
volume of lower-pressure air to enter the chamber.
As the chamber altitude approaches the altitude on the outside of
the chamber the door will open at the top by itself.
