Before operation, all persons who are to use the device or perform maintenance
on it must be provided with information, instructions and training in using the
device and on the substances for which it is to be used, including the procedure
for safe disposal of the collected material. Responsibilities must be clearly
established for the following:
Installation
Start-up
Operation
Maintenance and repair
The device must be used only by persons who have been instructed in its
handling and are explicitly authorized to use it.
Always keep the operating manual at the place where the dust extractor is being
used, so that it can be seen by personnel at all times.
The dust extractor is intended only for dry cleaning and must not be used or
stored outdoors or under wet conditions.
No liquids, aggressive gases, easily flammable materials or glowing particles
(such as hot embers) may be aspirated. For example, it is prohibited to use the
dust extractor in painting operations. It is forbidden to exhaust processing
machines with active ignition sparks or hot embers (such as multi-blade saws).
Installation and operation in dust-explosive or gas-explosive areas is forbidden.
Only original ESTA replacement parts must be used; use of other products will
void the warranty.
During exhaust, the volume flow returned from the dust extractor into the room
must be no more than 50% of incoming air. With free room ventilation, the
incoming airflow must equal the room volume every hour. This means that the rate
of air replacement must be once per hour.
Incoming airflow [m³/h] = room volume [m³] air replacement rate [1/h]
Example:
When the ESTA dust extractor is operating at the nominal airflow volume of 1200
m³/h the same volume of fresh air must therefore be fed in. This occurs with
natural ventilation if the volume of the work room is 1200 m³ (e.g., 400 m² surface
with a 3 m ceiling height).
