I posted some info. about this system about one year ago. The system is purged
once every 15 min's during use. The max. time from a 2l O2 tank includes the
O2 required for this purging. Purging is done by pressing a red button, that 
incresses flow to 15 liters/minute for a few secs. The normal flow rate should
be set to insure that enough O2 is input to the system for the needs of the
diver. This can be controled by watching the breathing bag on the system. The
bag can also be used to resperate the diver.
