The total heating time is about 2 hours. After about 1 hour, the lower
parameter value ( 30°C [54 °F] below set value) is exceeded.
For safety reasons, the low pressure gauge must show a low pressure of
> -0.6 bar. With a low pressure of < -0.6 bar, the critical orifice will not
function properly. If the necessary low pressure will not be reached, the
dilution gas pre-pressure must be increased.
