Note: The recovery times of the gas concentrations inside the chamber following door opening, which are
indicated in the technical data (chap. 22.4), refer to a connection pressure of 2.0 bar / 29 psi. Decreasing
supply pressure down to the shift point (alarm point) of 0.3 bar / 4.4 psi results in longer recovery times.
Check the pressure displays of your gas supply. If very short recovery times are required or the door is
opened frequently, replace the gas cylinders promptly when the pressure decreases below 2.0 bar / 29
psi.
