8 STORAGE
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 connected the
cylinder valve shall always have a protective plug.
9 EXTRA AIR CONNECTION
Some models are equipped with an extra air connection which can be used to:
connect to a chemical suit ventilation system
1.
connect a rescue hose between two apparatus
2.
connect an extra mask
3.
connect the resuscitation mask Revitox or the EVAC evacuation hood
4.
feed the apparatus from an external air source
5.
When taking air from the apparatus, 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 opens 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.
10 USAGE WITH AIRLINE SYSTEM
The instructions in Section 1, Section 2 - "Cylinder mounting - single cylinder" and
Sections 3 - 12 apply to usage with airline system.
The airline supply hose is connected to the male coupling on manifold located on the
right-hand side (as worn) of the waist belt.
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.
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.
Read and note the pressure reading on the pressure gauge of the SCBA.
1.
Connect the quick coupling of the SCBA to the airline supply hose. The higher
2.
pressure in the supply hose should shut off the supply from the SCBA.
After two minutes, read the pressure displayed on the pressure gauge again.
3.
During the elapsed time, there should be no measureable drop in pressure on the
