5. Commissioning
Dangers arising from a defective condition of the unit.
Make sure that the measures described in this chapter are completed before the
commissioning of the unit. All doors of the unit must be closed and all necessary connections
must be attached before turning the unit on. Do not operate the unit if any components are
defective, missing or damaged. Check the orderly condition of the unit before switching it on.
The unit must not be operated without a filter element.
Increased risk of explosion when filter unit switched off.
If the filter unit is left switched off while work is performed at the extraction points then dust
may collect at the extraction points. If the dusts in question are potentially explosive then this
increases the risk of explosion. In its risk assessment for the overall system, the Operator
must therefore ensure that
1) the filter unit is switched ON before any dust/fume-generating work is performed,
2) dust/fume-generating work is ceased promptly when the filter unit is switched OFF
either voluntarily or due to a fault message.
The Operator must also note whether shut-off valves are present between the extraction
point and the filter unit. These must be open while the work is being performed.
Damaged supply lines.
Make sure that the supply lines are protected against damage by forklift trucks and similar
events. Protect all supply lines from heat, moisture, oil and sharp edges.
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).
Explosion hazard!
The lines must be kept as short as possible and must be laid to the extraction point in a way
that optimizes the flow in order to prevent any deposits from forming in the lines. TEKA
Absaug und Entsorgungstechnologie GmbH expressly draws your attention to the fact that
extraction lines that have not demonstrably been configured by TEKA are not covered by the
filter unit’s explosion protection documentation. These must be configured for the application
in question.
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 purified air is led back into the working environment via the exhaust air grille (see chapter 2.1)
(recirculation mode). If it is desired to lead the purified air out of the working environment, an exhaust air
pipe must be attached at the discharge grille.
