Accidents can occur when this energy is improperly handled. Be sure that all equipment used is compatible and designed to control the pressures encountered. Oxygen is an oxidizing gas and is chemically stable and nonflammable. However oxygen does support combustion. High concentrations can accelerate the combustion of flammable materials up to and including an explosion. It is important to understand that spontaneous combustion of organic materials can occur in oxygen rich atmospheres. Oxygen handling must be done with care to avoid any association with hydro-carbons. Especially where fuels and lubricants are present in aircraft service areas. It is imperative that oxygen systems be handled properly. Be sure to keep all protective caps in position on equipment as long as possible, and replace them as soon as possible. Oxygen flowing at a high velocity in a piping system can propel any foreign material particles with such force that the impact friction can raise the particles temperature to a possible ignition point. It is, therefore, imperative that a high degree of cleanliness be maintained in the oxygen system at all times. Lubrication: The use of lubrication in an oxygen system shall be held to a minimum. No lubrication shall be applied in any area which will come into direct contact with oxygen during normal use. 3.1 GENERAL SAFETY REQUIREMENTS continued on following page. - 5 -
3.1 GENERAL SAFETY REQUIREMENTS WARNING! Only lubricants compatible with high pressure oxygen shall be used. SAE AIRCRAFT OXYGEN SPECIFICATION INFORMATION For more information concerning specific SAE aircraft oxygen equipment specifications, contact: Society of Automotive Engineers 400 Commonwealth Drive Warrendale, PA 15096-0001 4.0 PREPARATION FOR USE/ASSEMBLY INSTRUCTIONS 4.1 UNPACKING The oxygen cart s manifold system and oxygen booster have been thoroughly cleaned and inspected prior to packaging and shipment. After opening the shipping container and removing the unit, inspect it thoroughly for shipping damage. Oxygen equipment should be kept clean, dry, and free from contaminants. It is imperative that all installation, inspection, maintenance, testing, and servicing of oxygen system components be done by trained and qualified personnel using approved procedures. 4.2 ASSEMBLY 4.2.1 Inspect all connections for contaminants before installation and tightening. Remove any foreign materials. Be sure all oxygen system components are clean per SAE specification AIR 1176. 4.2.2 Install and rotate the oxygen supply bottles so that the manifold inlet hoses may be easily connected to the bottles. Tighten bottle hoses 2 to 2½ turns after finger tight is reached. Make sure the hoses are not kinked or damaged. Recheck all fittings for tightness. (See Figure 3). 4.2.3 If less than four bottles are used, plug or cover unused inlet hoses to ensure cleanliness. 4.2.4 Place the High Pressure Oxygen Gas Booster on the Four Bottle Cart and secure with the supplied hardware (See Figure 4). 4.2.5 Install 36 inch oxygen supply hose from regulator assembly to gas inlet on Oxygen Booster per SAE spec. ARP 1532, being careful not to contaminate the system during installation. (See Figure 3). 4.2.6 Install the 180 inch oxygen output hose onto the Oxygen Booster per SAE spec.

4.0 PREPARATION FOR USE/ASSEMBLY INSTRUCTIONS 4.3 PREPARATION FOR OPERATION WARNING! If there are any differences between the following instructions and the aircraft maintenance manual, the aircraft maintenance manual will take precedence. 4.3.1 Attach one static discharge cable clamp to aircraft static ground. (See aircraft maintenance manual if any questions.) 4.3.2 Attach other static discharge cable clamp to earth static ground. (See aircraft maintenance manual if any questions.) 4.3.3 Be sure all valves and controls are in the closed or OFF position. 4.3.4 Decrease air pressure regulator to the minimum pressure setting. 4.3.5 Decrease the oxygen supply bottle pressure regulator to the minimum pressure setting. 4.3.6 Connect the oxygen fill line loosely to aircraft and purge line by SLOWLY cracking open oxygen supply bottle shutoff valve and adjusting the supply bottle pressure regulator to a low flow setting. WARNING! Be sure fill line is secured prior to purging the unit. This will prevent the hose from whipping if too much oxygen is allowed to flow through the unit. 5.0 OPERATION 4.3.7 Tighten oxygen fill line connection at aircraft. 4.3.8 Verify the Speed Control Valve (See Figure 1 Item 9) is fully closed. 4.3.9 Connect shop air line to oxygen booster air drive inlet connection. (See Figure 1) 4.3.10 The high pressure oxygen booster is now ready to charge an aircraft oxygen system. 5.1 CHARGING THE AIRCRAFT OXYGEN SYSTEM 5.1.1 After the oxygen booster has been properly connected, fully open the oxygen supply bottle shut off valve. Adjust the oxygen supply bottle pressure regulator to the required aircraft oxygen system pressure. NOTE: If the supply bottle pressure is lower than the required aircraft oxygen system pressure, be careful not to over adjust the supply bottle pressure regulator once the maximum supply bottle pressure has been achieved. Increasing the oxygen supply bottle pressure regulator beyond this point will not increase the output and may damage the regulator spring. This will charge both the oxygen booster and the aircraft oxygen system to the set regulated pressure or to the lower available oxygen supply bottle pressure. If the oxygen supply bottle pressure is lower than the aircraft oxygen system pressure, check valves in the oxygen booster will prevent back flow of oxygen from the aircraft. 5.1 CHARGING THE AIRCRAFT OXYGEN SYSTEM continued on following page. - 8 -
5.1 CHARGING THE AIRCRAFT OXYGEN SYSTEM 5.1.2 As a benchmark, adjust the shop air pressure regulator to the adjusted pressure as required by the chart located on the oxygen booster operating instructions label. NOTE: Since the oxygen booster pump compression ratio is 30:1, 60 PSIG of shop air inlet will develop approximately 1800 PSIG of output oxygen pressure. 5.1.3 Open the shop air speed control valve (see Figure 1 Item 9) to pressurize aircraft oxygen system. Close the shop air speed control valve when desired aircraft oxygen pressure level is obtained. NOTE: Because the oxygen booster operates theoretically at a 30:1 ratio, actual boosted oxygen pressures may vary slightly due to different physical conditions. The oxygen outlet pressure gauge (see Figures 1 & 2, Item 10) will show the aircraft system pressure developed by the oxygen booster. It is suggested that the unit system pressure be adjusted below the required aircraft pressure to prevent over-pressurization. If the set pressure that has been achieved is less than the required system pressure, increase the pressure of the shop air regulator to obtain the required final aircraft system pressure. If non-standard ambient temperatures are present at the time of oxygen system recharging, refer to Table 1 below to determine the proper filling pressure for oxygen cylinders.

5.0 OPERATION 5.2 DISCONNECTING OXYGEN BOOSTER FROM AIRCRAFT WARNING! When the aircraft fill line is pressurized or when oxygen is flowing through the system, the fill line hose will whip if not secured. 5.2.1 Close the oxygen supply bottle shut off valve. This will stop inlet oxygen flow. 5.2.2 Decrease both the shop air inlet pressure regulator and the oxygen supply bottle pressure regulators to their respective minimum settings. 5.2.3 Disconnect shop air supply line. 5.2.4 SLOWLY loosen, bleed down, and disconnect aircraft oxygen fill line from the aircraft. 5.2.5 Cap aircraft oxygen fill line connection to prevent oxygen hose and system contamination. 5.2.6 Disconnect static discharge cable clamps from the aircraft static ground along with disconnection from the earth static ground. (See Aircraft Maintenance Manual if any questions.) 5.3 TO READ INDIVIDUAL BOTTLE PRESSURE 5.3.1 Close outlet shut off valve. 5.3.2 Open a bottle shutoff valve. 5.3.3 Read pressure on manifold pressure gauge. 5.3.4 Close bottle shutoff valve. 5.3.5 Open outlet shutoff valve and slightly adjust pressure regulator to bleed off manifold pressure. 5.3.6 Repeat procedure for other bottles. 5.4 EFFICIENT USE OF SYSTEM Maximum oxygen may be removed from supply bottles if aircraft are serviced from the lowest pressure bottle first. In this manner, the most oxygen 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.
