3.1 GENERAL SAFETY REQUIREMENTS
Pressures: Gases under pressure are a potential hazard in the form of stored energy. 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: 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.
Handling: 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.
Velocity: 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.
Oxygen Servicing: The following list contains additional general safety precautions that should be adhered to during the
servicing process. However, always refer to the manufacturer's procedure for the airplane being serviced.
1. Always ground the system to be serviced and the servicing equipment before connecting the filler adapter.
2. Close the oxygen bottle manual shutoff valve.
3. Ensure that all aircraft electrical power is off. Do not operate electrical switches, or connect or disconnect
ground power generators during the oxygen charging operation.
4. Do not service the oxygen system if fueling or other flammable fluid servicing is in process.
5. Do not charge the system too fast. Rapid charging can create a dangerous overheating condition.

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.
Though this unit has been functionally and pressure tested prior to leaving out facility, it is possible that some of the installed
fittings may have loosened during shipping. It is advised that all connections be checked for tightness as part of the installation
process.
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
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.
2. Install 12 inch oxygen supply hose from regulator assembly to
gas outlet on Oxygen Booster per SAE spec. ARP 1532, being
careful not to contaminate the system during installation. (See
Figure 2).
3. Install 12 inch oxygen supply hose from manifold assembly to
gas inlet on Oxygen Booster per SAE specification ARP 1532,
being careful not to contaminate the system during installation
(See Figure 2).
4. 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 2).
5. If less than four bottles are used, plug or cover unused inlet
hoses to ensure cleanliness.
6. Check that outlet shut off valve is closed. Carefully store outlet
hose in cart storage tray.
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.
1. Attach one static discharge cable clamp to aircraft static ground. (See aircraft maintenance manual if any questions.)
2. Attach other static discharge cable clamp to earth static ground. (See aircraft maintenance manual if any questions.)
3. Be sure all valves and controls are in the closed or “OFF” position.
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.
