integral Lung Demand Valve (LDV).
Alternatively:
Pressure Reducer with HP Gauge, Whistle Warning Unit (WWU) and
medium pressure hose with Quick Release Coupling (QRC).
● Airline Manifold Connection.
● Valved Cylinder Assembly.
The equipment is available in either 10 minute or 15 minute nominal
duration versions.
4.1 Optional Variants
● Cylinder Carrying Holster – Drop Down. If applicable, refer to
additional enclosed Instructions for Use.
4.2 Accessories
● Thigh strap
This series of equipment is compatible with a range of lung demand valves,
face mask and compressed air cylinders. When used in approved carrying
system, valved cylinder assembly, LDV and face mask combinations, the
equipment provides the wearer with respiratory protection when working in
a contaminated or oxygen deficient gaseous atmosphere.
The effective duration of the equipment is dependant on the capacity
(volume) of the cylinder selected and the breathing rate of the wearer.
Details of the equipment variants, accessories, and any approved
independent air supply source configurations are available from Dräger on
request.

● Two Users – 7bar to 10bar - airflow rate of at least 550 Litres/minute.
Safety Warning: Air quality for compressed air breathing systems
must conform to the requirements of EN12021. Do Not use oxygen or
oxygen enriched air.
6 Preparation for Use
A trained and competent person must perform the following checks and
preparation procedures before release of the equipment to a potential
wearer for operational use.
6.1 Visual Inspection
Check the integrity of,
● Bandolier Shoulder Harness with Waistbelt.
● Hip Mounted Cylinder Carrying Holster.
● Pressure Reducer with HP Gauge, Whistle Warning Unit (WWU) and
integral Lung Demand Valve (LDV).
Alternatively;
Pressure Reducer with HP Gauge, Whistle Warning Unit (WWU) and
medium pressure hose with Quick Release Coupling (QRC).
● LDV – refer to the relevant Instructions for Use.
● Airline Manifold Connection.
● Valved Cylinder Assembly.
6.2 Fitting Cylinder
● Check that the threads of the valve port and the reducer hand wheel
are undamaged, connector O ring is in position, and undamaged. Fully
insert the fully charged cylinder into the carrying holster.
Caution: To prevent damage, ensure that the hand wheel of the
pressure reducer remains clear of the cylinder.
● Screw the hand wheel of the pressure reducer (clockwise) to the port
of the cylinder valve and tighten the hand wheel - handtight.
6.3 Connecting LDV to QRC
This instruction refers to equipment with medium pressure hose with QRC.
● Insert the male coupling of the LDV into the female QRC of the
equipment medium pressure hose. Check the security of the
connection. Refer also to the Instructions for Use provided with the
LDV.
Important Note: The following test will verify the integrity of the
assembly. The pressure leak test described should also be carried
out following the reassembly of any of the component parts of the
pneumatic assembly (spares etc.).
6.4 HP Leak and WWU Test
● Type PP LDV's - Press the reset button of the LDV to switch 'Off'
positive pressure.
Instructions for Use
● 'Open' the cylinder valve slowly, but fully, to pressurise the system
then 'Close' the valve and observe the gauge.
Test Parameter – Indicated pressure on gauge should not decrease more
than 10bar in 1 minute.
● Proceed to test the whistle warning unit.
● Type PP LDV's – Cover and seal the outlet of the LDV with the ball of
the hand. Press carefully the centre of the rubber cover then lift the
hand to slowly vent pressure.
● Type N – Carefully press the centre of the rubber cover to slowly vent
pressure.
● Observe the gauge during venting. The whistle should sound at the
preset pressure of 55bar +/- 5bar.
● Type PP LDV's - Press the reset button of the LDV to switch 'Off'
positive pressure.
● Should the whistle not sound at the preset pressure, refer to Dräger
Service.
6.5 Leak Test and LP Flow Test -Airline Connection
Refer to Technical Data.
Important Note: If using a works airline to perform the following tests,
then connect the isolation valve (3353449) to the female coupling of
the airline outlet.
● Connect the male coupling (1) Fig. 2 to the female QRC of the
independent air supply.
● Type PP LDV's - Press the reset button of the LDV to switch 'Off'
positive pressure.
● 'Open' the valve of the independent air supply to pressurise the
system.

● Fully extend (open) the straps of the head harness.
Type A
● Check that the face mask port and the connector O ring of the LDV are
clean and undamaged.
● Push the connector of the LDV into the port of the face mask until it
'clicks' in position.
● Check that the attachment is secure by pulling the LDV away from the
face mask
○ there should be no axial movement.
Types AE and N
● Check that the face mask port and sealing ring are clean and
undamaged.
● Screw the hand wheel of the LDV into the port of the face mask, align
the LDV as shown in Fig. 1 then finally tighten.
● Having 'passed' the test, and the LDV fitted to the face mask, the
equipment is now available for use.
7 Use
7.1 Putting on equipment
● Extend the shoulder strap. Open the buckle of the waistbelt and extend
the strap at the male buckle end of the strap. Leave the female buckle
in position.
● While supporting the face mask, place the left arm through the
shoulder harness, taking the harness over the head and onto the right
shoulder, positioning the strap diagonally across the body with the
cylinder/carrying holster positioned against the left hip. Loop the
waistbelt around the waist and fasten the buckle – Do Not tighten. Put
the neck strap of the face mask over the neck then insert the neck strap
stud into the hole in the centre strap of the head harness. Face mask
is now in the ready position.
● Grip the cylinder valve with the left hand and lift until the waistbelt is in
line with the waist then pull the free end of the waistbelt strap, through
the male buckle, until the equipment is secure and comfortable on the
waist. Pull down and adjust the shoulder strap.
Figure 2 shows the correct wearing position.
7.2 Pre Operational Checks
● Type A and AE - Press the reset button of the LDV to switch 'Off'
positive pressure.
● 'Open' the cylinder valve.
Note: Refer to Instructions for Use provided with the Face mask.
Safety Warning: Facial hair, beard stubble, side-whiskers, and the
wearing of spectacles will adversely affect and interfere with face
mask seal. Correct fit of face mask only ensured if face mask seal
makes close contact with skin.
