Efficient Use of System

Maximum pressure may be removed from supply bottles if aircraft are serviced from the lowest pressure bottle first. In this manner, the most Nitrogen may be removed from each bottle. Even bottles with relatively low pressures may be used to service aircraft if the aircraft has a depleted system.
