Pipe system blow through process
Figure 112: Lever position on the ball valve
The pipe system manual blow through process should be conducted in the
following stages:
1. Connect the compressed air supply needed for free-blowing the pipe
system (compressor or mobile free-blow device) via the quick release
coupling muff to the 3-way muff ball valve on the pipe system to be
blown through.
2. Separate the pipe system to be blown through by the 3-way muff ball
valve from the corresponding device, by moving the ball valve lever from
the 0° operating position to the 180° position (see Figure "Lever position
on the ball valve").
3. Blow the pipe system free manually for about 10 seconds.
4. Put the ball valve lever into the 90° position. In this position, the device
cannot be connected either to the pipe system or the compressed or
pressed air supply connection. Wait about 20 seconds so that the dust
and dirt stirred up in the pipe system can settle and thus not be aspirated
via the air sampling smoke detection system.
