Shortfall Below Minimum Volume Flow; Positioning Of The Suction Hood - Kemper Filter Master XL Manual De Uso

6.3 Shortfall below minimum volume flow

Acoustic signal generator for shortfall of the minimum volume flow
With increasing operating time, the main filter becomes increasingly dirty and thus
the extraction capacity of the device is reduced. If the flow required for the reliable
detection of the welding fumes of 710 m³/h is undershot, a beep calls attention to this
state. In this case, a filter change is usually necessary. Other reasons for
undershooting the minimum volume flow are available in the table below Point 7.6,
Fault clearance here, the necessary remedial action is also indicated.

6.5 Positioning of the suction hood

The exhaust arm and the exhaust hood are designed so that they can be easily
adjusted and pulled into position with one hand. Once adjusted, the exhaust hood
remains in that position of its own accord. Furthermore, both the suction hood and
the exhaust arm can swivel 360°, so that almost every position can be set. For
adequate capture of welding fumes, it is important that the exhaust hood is always
positioned correctly. The correct position can be seen in the following picture.
• Position the extraction arm so that the extraction hood is located approx.
25 cm diagonally above the weld.
• The exhaust hood must be positioned so that it safely captures the welding
fumes, taking into account the movement of welding fumes caused by the heat
and the suction range.
• Always move the exhaust hood with respect to the weld position as you
advance.
WARNING
An incorrectly positioned exhaust hood or too low an extraction efficiency
do not ensure that hazardous substance-containing air is captured
adequately by the exhaust hood. Hazardous substances can thus enter
the area where the user breathes and lead to injury to health!
