INTERSPIRO IS NOT RESPONSIBLE FOR
COMBINATIONS OF PRODUCTS, UNLESS PUT TO MARKET BY INTERSPIRO
CHANGES OR ADAPTATIONS MADE TO THE PRODUCT BY A THIRD PARTY

13
Changes to this manual may be made at any time without prior notice if necessary
due to typographical errors, inaccuracies in information, or due to improvements or
changes to the equipment. Visit www.interspiro.com for product and documentation
updates and service announcements.
Exposure to extreme conditions may require measures other than those described in
this user manual. Interspiro’s responsibility and warranty conditions are not extended
or aected by these safety regulations.
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 specic to the
wearer and aected by the work load. When taking air from the extra air connection,
which some models are equipped with, the air consumption increases and the
duration of the apparatus decreases.
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 eects
- Explosive environments.

4. Remove the appaaratus and activate the positive pressure to purge air from the
system.
8. CLEANING AND DISINFECTING
1. Disconnect the breathing valve from the face mask. Do not disconnect the
breathing hose from the breathing valve.
2. Mount a wash plug on the breathing valve and on the whistle.
3 When washing the cylinder use wash plug 32350-51 on the cylinder valve pressure
gauge if applicable.
4. Open the cylinder valve and check that there is pressure in the system before
cleaning.
NOTE! HAVING THE CYLINDER VALVE OPEN PREVENTS WATER FROM ENTERING THE SYSTEM AND BUBBLES WILL
INDICATE ANY LEAKS IN THE SYSTEM.
5. Spray on or submerge the breathing apparatus in water and cleaning solvent. Use
cleaning solvent recommended by Interspiro, max. 55°C.
6. Clean the apparatus with a sponge or brush.
7. Rinse the apparatus in clean water, max 60 °C.

instructions in the user manual for the face mask.
9. STORAGE AND TRANSPORT
Store in a cool, dry and dust-free environment. Protect rubber parts from direct
sunlight, UV radiation and direct heat. When the regulator unit is not conneted the
cylinder valve shall always have a protective plug.
During transport the product must be whell protected inside the original packaging
material or equivalent packaging material.

18
10. EXTRA AIR CONNECTION
Some models are equipped with an extra air connection which can be used to:
1. connect to a chemical suit ventilation system
2. connect a rescue hose between two apparatus
3. connect an extra mask
4. connect the resuscitation mask Revitox or the EVAC evacuation hood
5. feed the apparatus from an external air source
When taking air from the appartus, point 1-4 above, the air consumption increases
and the duration of the apparatus decreases.
A special female coupling with a non-return valve opener must be used when taking
air from the apparatus, point 1-4 above. This device openes the non-return valve in the
male connection on the apparatus.
When feeding the apparatus from an external air source, this kind of female coupling
must not be used. In this application, the non-return valve in the male connection
must be able to close in case of disruption in air supply from the external source.
11. RESCUE HOSE
The apparatus may be equipped with a rescue hose that can be used to share air
between two users in an emergency.
A user with a lot of air (donor) shares his air with a user with little air (receiver). But
the air will not only be taken from the donor when you have connected the devices.
The air will be consumed from both apparatuses and may be taken alternately from
the dierent appratuses depending on variations in the regulator pressure and the
breathing rhythm of the users.
The rescue hose is mounted according to [Fig. 20]. To use the rescue hose, grasp the
Y-coupling and pull the hose free from its attachment.
The rescue hose has a male and a female connection so that they can be connected
together.
NOTE! ALWAYS FOLLOW YOUR ORGANIZATION’S ESTABLISHED PROCEDURES FOR RESCUE HOSE USE.
12. USAGE WITH AIRLINE SYSTEM
When operating on supplied air from the airline hose, the cylinder valve on the SCBA
should be closed.
Should the supply from the airline hose be disrupted, fully open the cylinder valve of
the SCBA.
When the cylinder valve has been opened, the user must immediately leave the
hazardous area. Disconnect the airline hose if necessary.

19
When operated with cylinder valve opened and used in conjunction with an automatic
switch between the airline supply and SCBA cylinder, the following instructions
should be observed.
1. Read and note the pressure reading on the pressure gauge of the SCBA.
2. Connect the quick coupling of the SCBA to the airline supply hose. The higher
pressure in the supply hose should shut o the supply from the SCBA.
3. Aer two minutes, read the pressure displayed on the pressure gauge again.
During the elapsed time, there should be no measureable drop in pressure on the
gauge. This check will indicate that the higher pressure in the airline supply hose is
preventing air from being taken from the SCBA cylinder.
4. During usage in the hazardous environment, periodically check the pressure
displayed on the gauge and if a decrease is noted discontinue use. Disconnect the
airline hose and exit to a safe area using the bail-out set as an escape apparatus.
