The breathing air with which the cylinders are charged must meet the requirements according to EN 12021, being free from oil, toxic substances and having low humidity. The duration of a compressed air breathing apparatus depends on the volume of air in the compressed air cylinder(s) and the air consumption, which is specific to the wearer and affected by the work load. When taking air from the extra air connection, the air consumption increases and the duration of the apparatus decreases.

If the ambient temperatures is 0°C or below, external icing can cause malfunction of the warning whistle. Under such circumstances the pressure gauge must be read more frequently. When operating with two separate independently valved cylinders, both cylinders must be charged with similar working pressures. Always open both cylinder valves when pressurizing the breathing apparatus and ensure that both cylinder valves are kept open during the use of the apparatus.

If the self-contained breathing apparatus is to be used in conjunction with other personal protective equipment, it is important to ensure that the additional personal protective equipment is compatible with the breathing apparatus and does not impair the full protection of the respiratory protective device.

Examples of dangers which may require the use of additional personal protective equipment:

• Liquids, steam or gases which can damage the skin
• Pollutants absorptive by skin
• Thermal radiation
• Mechanical effects
• Explosive environments

1 Cylinder Mounting

1. Place the cylinder on the backplate.
2. Check the connection O-ring and screw the cylinder valve hand tight to the cylinder connection of the manifold block.
3. Fasten cylinder strap around the cylinder and hook together with the buckle. Adjust the length of the strap if needed. Do not over tighten. If the strap is over tightened, the buckle and backplate will be damaged.
4. Close the lever on the buckle. Make sure that the locking tab has locked the lever in the closed position. (To release the cylinder buckle, the locking tab must be pressed down.)
