U-Clip and hoses are not to be removed after removing the pressure
reducer.
(6) Clean carrying plate with cylinder strap at max. 60°C
(7) Clean harness in a suitable washing machine at max. 60°C
(8) 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.
(9) 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 Section 4.7).
(2) Connect compressed air cylinder to carrying plate (see Section 3.1).
(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 and check operating pressure on the pressure gauge.
▪
The pressure values must read:
(5) Close cylinder valve.
▪
After 60 seconds the pressure drop in the pressure gauge must not
exceed 10 bar.
(6) Check warning device (signal whistle) (see Section 4.5).
4.5. Setting the Warning Device
The release pressure of the warning device is set ex-works at 1055 bar. This
ensures that, even with small compressed air cylinders, when the warning signal
sounds there is sufficient air for breathing to allow exiting from the area of use.
When using compressed air cylinders with larger air reserves (e.g. 4 l/200 bar)
you can set the release pressure lower, but not less than 555 bar.
