2 Description
2.1 Product overview
®
The Dräger PSS 5000 Series is a self contained breathing apparatus
(SCBA) that uses an open-circuit breathing system. The series is
compatible with a wide range of compressed-air cylinders, face masks and
lung demand valves (e.g. FPS 7000 and Panorama Nova face masks, PSS
Series lung demand valves, and steel or composite cylinders).
The apparatus can also be fitted with a multi-function electronic monitoring
®
system (e.g. Bodyguard 7000). Refer to the relevant Instructions for Use
for the description, operation and testing of electronic systems.
2.2 Feature description
The carrying system has a carbon-composite backplate, with adjustable
shoulder straps and waist belt connected using quick release connectors.
A waist pad (Fig 1, Item 6) connected at a flexible joint compensates for
the twisting and bending of the user. Cylinder mounting systems include a
single cylinder strap (2) or a universal cylinder strap for use with twin
cylinders.
The apparatus uses the Dräger high-performance pressure reducer (4)
that reduces cylinder pressure and supplies breathing air through a
medium-pressure hose (5) and coupling (1) to the attached lung demand
valve. A dual-pressure hose (3) supplies air to the whistle when it is
activated, and has an internal capillary tube that supplies high-pressure air
from the cylinder to the gauge. Air hoses and modular components of the
monitoring system are integrated into the backplate to prevent snagging
and enhance component protection.
Compressed air cylinders, lung demand valves and face masks
The Dräger PSS 5000 Series is compatible with steel or composite
material cylinders of 4 to 9 litre capacities, and 200 or 300 bar pressure.
Full descriptions and user instructions are contained in separate
instructions supplied with the cylinder, mask or lung demand valve.
2.3 Intended use
The Dräger PSS 5000 Series breathing apparatus, when fitted with a
cylinder, lung demand valve and face mask, is intended for use by
emergency services and in industrial applications where a high level of
respiratory protection is required. The assembled breathing apparatus
provides the wearer with respiratory protection for working in contaminated
or oxygen-deficient conditions, and is suitable for fire fighting.
The cylinder, lung demand valve, face mask and other accessories used
with this product must be certified Dräger components, assembled in an
approved configuration. Contact Dräger for further information.
Use in potentially explosive atmospheres
The PSS 5000 Series is type tested as suitable for use in potentially
explosive atmospheres. Electronic sub-assemblies are ATEX certified.
All combinations are suitable for use in hazardous areas up to and
including zone 0 and zone 20.
2.4 Approvals
The European standards, guidelines, and directives according to which
this product is approved are specified in the declaration of conformity (see

WARNING
Only trained and competent personnel may prepare and use
breathing apparatus. Ensure that any accessories, ancillary
equipment and other protective clothing items do not interfere with
the apparatus and do not create a safety hazard.
The effective working duration of the apparatus is dependent on
the initial air supply available and the breathing rate of the wearer.
Fill all air cylinders to their full rated pressure prior to use, and do
not commence any operation using a cylinder that is less than
90 percent full (or greater when national regulations dictate).
CAUTION
Do not apply excessive force or use tools to open or close a
cylinder valve, and do not drop or throw down the breathing
apparatus.
3.1 Preparation for use
NOTICE
The face of the pressure gauge may be fitted with a thin flexible
protective covering. Remove this covering before first use.
1. Carry out a visual inspection of the apparatus (see Section 3.5.1).
2. Fit the air cylinder (see Section 3.5.2).
3. For breathing apparatus with a medium-pressure coupling for the lung
demand valve, disconnect and then reconnect the male coupling. To
connect, press the male coupling into the female coupling until an
audible click is heard. If there is any difficulty disconnecting or
connecting, see the troubleshooting information in Section 4.
4. Press the reset button when using a positive-pressure lung demand
valve (see the Instructions for Use supplied with the lung demand
valve).
5. Carry out a full functional test of the apparatus (see Section 3.5.3).
6. Connect the lung demand valve to the face mask and check the
security of attachment by gently attempting to pull the coupling apart.
3.2 Putting on the breathing apparatus
1. Fully loosen the shoulder straps and waist belt and put on the breathing
apparatus.
Instructions for use
