5.1. Connecting the suction line and exhaust air line
For extracting the contaminated air, a suction line must be connected to the suction nozzle (see chapter
2.1).
Danger for the respiratory tract arising from polluted ambient air. Dust deposits in the
suction pipe are possible.
Only operate the system if the necessary suction line is fitted. The suction line must be
dimensioned according to the application in such a way that, if possible, no dust deposits
occur in the suction line. If this has not already been carried out by TEKA, a suitably qualified
employee must be consulted. If the suction line includes extraction elements (e.g. suction
arms, pipe grills, etc.), these must also be included in the layout. If this is the case then users
must be informed of whether extraction elements can be used simultaneously and, if this is
possible, then which. The regulating devices (e.g. throttle valves) of each single extraction
element must also be set appropriately during the final commissioning.
Depending on the application, the suction pipe must be equipped with extraction elements (suction arm,
extraction hose, round duct grille, etc.). When using a capture element with an extractor cowl, the
extractor cowl must follow the weld seam, if possible by using the movement of the welding fume
caused be thermal influences.
You have to make sure that connections between the workpiece and the suction
hood (and in general between the workpiece and the filter unit) are avoided in order to prevent
the welding current from flowing back to the welding machine via the protective conductor of the
filter unit.
If the air shall be directly sucked off by an upstream machine, the suction line must be connected to the
capture opening of the upstream machine.
The exhaust air pipe must be attached to the exhaust nozzle (see chapter 2.1).
In the case of an optional fan housing standing alongside, the filter unit and the fan must be connected
by means of a connecting pipe.
Danger to life when reaching the fan impeller.
The exhaust air pipe must be attached before the commissioning.
If no exhaust air pipe is attached, the protective grille of the silencer must be installed.
