Figure 5-8.- TMU-70/ M liquid oxygen servicing trailer storage tank schematic diagram.

Figure 5-9 shows the operating instructions from the plate attached to the trailer. When the servicing trailer is received from the factory or from an overhaul activity, it is normally ready to be filled with LOX and pressurized for immediate use. The annular space is evacuated to the point desirable for a warm and empty tank. Prior to filling or pressurizing the tank, perform the inspection procedures indicated in table 5-1.
