10. This device may not reach specifi ed oxygen concentration purity until it has been in use
for up to 2 minutes at set fl owrate. Additional warm up time of up to 30 minutes may be
required to reach an optimum oxygen purity level, if the device has been stored/unused
for an extended period or kept in cold temperatures.
