For Your Safety

The Dräger PAS AirPack 1 Trolley Module incorporates a high performance pressure reducer. The reducer
is factory set and must not be tampered with, or removed from the manifold, as this invalidates the
conditions of the Dräger warranty. Correct operational condition is valid only if Dräger service and re-
seals the pressure reducer.
u Use of this equipment requires wearer training and observance of these Instructions for Use and the
Instructions for Use supplied with the selected associated breathing equipment.
u Use the equipment for the purpose specified in this instruction, or as confirmed in writing by Dräger.
u Use and maintenance of this equipment requires knowledge and compliance with National Regulations,
Laws and Standards governing the use of respiratory equipment in the country of use.
u Only trained competent personnel should inspect and service the equipment at regular intervals and
a record kept of such inspections and service.
u Only trained and competent personnel should carry out the charging of the compressed air cylinders.
u Dräger recommends that a Service Contract be obtained from your Dräger Branch or Agent.
u Contact Dräger for details of Service Contracts and Service Training Courses.
u Use only original Dräger Spare Parts for service and maintenance.
u Use only original Dräger Test Equipment for service and maintenance.
u Notify Dräger if there is a component fault or failure.
Liability Statement
Terms and Conditions of warranty for the Dräger PAS AirPack 1 Trolley Module can be obtained from Dräger
on request. Responsibility for reliable function of the equipment transfers to the owner or operator when
serviced or repaired by untrained personnel, (not employed or authorised by Dräger), or when used in a manner
not conforming to its intended use.

Pre-Use Procedures

Caution: Before connecting the selected airline
breathing equipment to the tested and released
Dräger PAS AirPack 1 Trolley Module, ‘check’
that the breathing equipment has been tested
by a trained and competent person before
being released for use. When in use the
AirPack 1 Trolley Module must be positioned
in a safe and uncontaminated area. Dräger
recommend that a ‘Controller’ must be present
at all times to monitor and maintain the air
supply to the wearer of the selected breathing
equipment. Time required for the wearer of
the airline breathing equipment to safely
evacuate from the hazardous area to a safe area
must be within the air capacity of the remaining
cylinder(s) of the PAS AirPack 1 Trolley Module.
Dräger recommend that the user(s) of this final
configuration operate and maintain a ‘Permit
for Use’ procedure and also have an
established company evacuation procedure(s).
The Dräger PAS AirPack 1 Trolley Module may be
used either as a self-contained unit, i.e. using the
attached compressed air cylinders, or by connecting
the module to an independent low-pressure air supply,
e.g. from a works airline or LP compressor the
cylinders can be bypassed.

u Regularly take a HP gauge reading. At between
60bar to 50bar the HPWWU unit sounds
indicating that the cylinder in use is almost
empty. To therefore maintain the air supply to
the wearer of the breathing equipment
immediately proceed as follows:
1. Slowly, but fully, 'Open' the valve of the
second fully charged cylinder. The HP gauge
5 6 7 8 (3) will indicate an increase in system pressure.
The wearer is now connected to the fully
charged cylinder.
2. 'Close' the valve of the empty cylinder then
'Open' the bleed valve (6) of the associated
valve to vent the remaining pressure from the
HP supply hose.
3. Unscrew the connector handwheel from the
valve of the depleted cylinder. Release the
Camlock mechanism of the cylinder support
strap and remove the cylinder.
4. Select an available replacement fully charged
cylinder and assemble to the trolley. See -

27bar/minute. Rapid charging will induce an
increase in temperature resulting in an incomplete
charge - check pressure at ambient and if required
‘Top Up’ charge.
To prevent overcharging of the selected cylinder
Dräger recommend that a pressure-limiting device
is fitted to the charging compressor.
Storage - Ready for Use
