4.3 General safety instructions
During extraction, the volume flow returned from the product into the room should
be no more than 50% of the air supplied. With open room ventilation, supply air
flow should be assumed as equal to the room volume every hour. This means that
the rate of air replacement must be once per hour.
Supply air flow [m³/h] = room volume [m³]
air replacement rate [1/h]
Example:
When the product is operating at the nominal airflow volume of 1,060 m³/h, the
same volume of fresh air must be fed in. This occurs with natural ventilation if the
volume of the work room is 1,060 m³ (e.g., 353 m² surface with a 3 m ceiling
height).
According to work equipment user directives 2009/104/EG and TRGS 560, safety
devices for prevention or removal of hazards must be regularly maintained and
regularly inspected by an expert for safe, flawless operation.
In all emergencies, the product must be disconnected from the power supply
immediately, turned off at the main switch and the plug pulled immediately.
4.4 Fire hazard prevention
A cyclone can separate sparks and glowing particles but the manufacturer does
not guarantee any protection from fire as a result. Spark detection and quenching
systems adapted to the application can be provided for this.
DANGER
Danger of fire due to sparks and glowing particles
If there is a fire, alert the fire department immediately, and contain the fire
by appropriate means.
Keep a suitable extinguishing agent near the product before start-up and
during operation.
