MAINTENANCE AND CARE OF THE SCBA MSA
16 BD 96 SL
GB
Do not remove the U-clip and hoses after removal of the pressure
reducer.
(8) Clean carrying plate and cylinder strap at max. 60°C.
(9) Clean harness in a suitable washing machine at max. 60°C.
(10) Clean lines, pressure reducer and pressure gauge by hand.
Attention!
Do not submerge pressure reducer into water. This can affect the
functioning of the pressure reducer.
(11) Completely dry all compressed air breathing apparatus components in a
drying cabinet at max. 60°C
4.4. Visual, Function and Tightness Check
(1) Visually check the high pressure gaskets (see 4.6).
(2) Connect compressed air cylinder(s) to carrying plate (see 3.1 and 3.2).
(3) Check all parts of the compressed air breathing apparatus for visible defects
or malfunctions, such as incorrectly assembled harness, loose compressed
air cylinders, incorrectly fitted lines, etc.
(4) Open cylinder valve(s) and check operating pressure on pressure gauge.
• The pressure values must read:
for 300 bar cylinders minimum 270 bar
for 200 bar cylinders minimum 180 bar
(6) Close cylinder valve(s).
• After 60 seconds the pressure drop in the pressure gauge must not
exceed 10 bar.
(7) Check warning device (signal whistle) (see 4.5).
4.5. Warning Device Check
(1) Connect lung governed demand valve to medium pressure line.
(2) Open cylinder valve(s).
• The pressure on the pressure gauge must be at least 120 bar.
(3) Close cylinder valve(s).
(4) Carefully activate flushing mode of lung governed demand valve (see
Instruction Manual for Lung Governed Demand Valve)
(5) Observe pressure gauge.
• The warning signal must sound at 55±5 bar.
4.6. High Pressure Gaskets Check
Visually check the sealing ring of the cylinder connector in the pressure reducer.
Damaged sealing rings must be replaced.
