Risk of death from dust explosion!
In areas with explosive dust atmospheres, compressed air and exhaust may not be
evacuated directly into the atmosphere. Dust accumulates in the system's atmosphere and
increases the risk of explosion.
Make sure that either the compressed air and exhaust in the dust explosion protection
area are evacuated from the dust explosion protection area through tubing lines or the
exhaust lines are mounted to permit the continuous controlled exit of penetrating dust.
Danger of explosion due to self-ignition of dust!
If the cylinder valve unit surface reaches the smoldering temperature of the accumulated
dust during continuous operation, the dust will self-ignite and can lead to an explosion.
Ensure that the minimum ignition energy of the dust in the system atmosphere is > 1 mJ.
Safeguard the cylinder valve unit from dust deposits, e.g. through protected installation.
Danger of explosion through overheating caused by large dust deposits!
The accumulation of dust can cause the cylinder valve unit to overheat. The surface can no
longer cool down and heats up at an uncontrollable rate. The resulting heat build-up
represents an explosion hazard.
If there are large amounts of dust in your system's atmosphere, a protected installation
of the cylinder valve unit can prevent the formation of dust deposits.

Installation conditions
7.2.1 Installation conditions in explosion protection
zones
Make sure that the compressed air is only generated and
prepared outside the explosive area.
7.2.2 Installation conditions in dust explosion protection
areas
DANGER
Dust deposits interfere with the cooling of the cylinder valve unit
and must therefore be regularly removed. With a protected
installation, you can avoid interruptions in the system's operation,
as fewer cleanings are required.
