ASV without warning device

GB
2.1 Function
The device automatically switches over breathable air supply from compressed air
feeding line to SCBA or from SCBA to compressed air feeding line, depending on
pressure differences between the compressed air feeding line pressures and the
SCBA.
In case of using the compressed air feeding line with a pressure reducer together
with compressed air cylinders, there is an acoustic retreat warning. The warning de-
vice at the pressure reducer of the compressed air line breathing apparatus acti-
vates at the latest by a cylinder pressure of 30 bar and emitting an audible signal.
While using an external compressed air feeding line breathing apparatus, the user
is supplied with breathable air from i.e. a SCBA, a compressed air cylinder (e.g. 50 l
permanent cylinder), via a compressed air line breathing apparatus (DSG) pressure
reducer or from a compressed air feeder.
The SCBA, the Lung Governed Demand Valve (LGDV) and the supply hose of the
external air supply from the pass thru of the chemical suit are connected to the de-
vice.

3.1 Preparations for Use
It is assumed that the device is ready to be put into service having undergone all
checks according to chapter 4.
3.2 Handling the Line Coupling
To connect:
Push plug nipple into coupling until coupling sleeve engages.
To disconnect:
Push plug nipple into coupling and at the same time pull back coupling sleeve.
Then plug nipple can be pulled out.
Attention!
When disconnecting the compressed air feeding line ends while they are
under pressure the plug nipple side must be held firmly. The escaping
air could otherwise cause the line to be propelled in an uncontrolled way
(especially long lines).
