USING THE COMPRESSED AIR BREATHING APPARATUS
3.5. Function of the Medium Pressure Coupling
Coupling
(1) Connect medium pressure line of lung governed demand valve until the
coupling audibly catches.
De-coupling
(1) Push the push-in nipple of the medium pressure hose into the coupling and
simultaneously pull back the coupling sleeve.
(2) Pull out the medium pressure hose from the coupling.
3.6. Condensed Prior to Use Check
Check can only be performed with connected lung governed demand
valve
(1) Open the cylinder valve and check the pressure on the combo pressure
gauge.
▪
The pressure values must read:
(2) Close cylinder valve and observe pressure gauge.
▪
The pressure must not drop more than 10 bar in 60 s.
(3) Carefully activate flushing mode of lung governed demand valve, closing exit
port as much as possible.
(4) Observe the pressure gauge.
▪
The warning signal must sound at the set pressure (factory pre-set is
1055 bar).
3.7. Donning the Compressed Air Breathing Apparatus
(Back Carrying Method)
(1) Check all components of the compressed air breathing apparatus for defects
and malfunctions.
(2) Don breathing apparatus with shoulder straps fully extended.
(3) Tighten shoulder straps till carrying plate fits comfortably
(4) Close hip belt and tighten by pulling the loose ends.
▪
The release button must point towards the body.
(5) Adjust shoulder straps to achieve a comfortable weight distribution between
shoulder straps and hip belt.
(6) If required, connect lung governed demand valve to medium pressure
coupling (see Instruction Manual for Lung Governed Demand Valve).
