The CO2 Bath is easy to use and operate but there are some things you must know and setup correctly.
First you must make sure the neck fits tight but not too tight. Before using the bath the first time see how the neck feels. If it is unbearable tight to the point of being very uncomfortable you can trim the neck seal. Additionally you can use a round container such as a 2 liter soda bottle to stretch it out. It should be a few inches larger than your neck and leave it overnight to stretch out.
Please make sure to take your time and cut on the line.
The remote control allows you to operate the bath functions from within the bath. You should always have an assistant help you with the bath in the event that something should go wrong.
There are 3 options on the remote control. The top left button turn on the vacuum and valves to vacuum out the air. The top right turn off the vacuum. Once all of the air has been vacuumed out then turn the vacuum off.
The middle left button turns on the co2. Before getting in the bath make sure the co2 tank is turned on and connected to the bath. No air will go in until you turn it on. Once the bath is filled with co2 use the middle right button to turn off the co2. If you absorb co2 during the bath and want to add more, then just press the left middle one again to let more co2 into the bath. The right middle button to turn off the co2 again.
The bottom left and right button are for whatever you want to use it for. You can use it to control a light in the room. The left button will turn it on and the right one will turn it off. This is useful if you are in the dark such as sleeping and you want to get out. This allow you to turn on the light.
The neck BioSeal is convenient if you have multiple people using the bath with different neck sizes. So a person with a large neck can use the same bath comfortably as someone who has a much smaller neck. The material of the neck seal is sticky so will adhere to the neck seal.
