Danger of poisoning/infection due to exhaust air
The exhaust air may contain harmful substances originating from the
product.
Contact with particles in the exhaust air (especially by inhalation) may
result in severe damage to health.
• Use a silencer with integrated filter elements or – depending on the
product – guide the exhaust gases from the outlet of the vacuum pump
to a suitable treatment system in order to prevent the discharge of
harmful substances into the surrounding atmosphere! Compliance with
the national rules and regulations for the protection of the environment
must be ensured!
•
When working on the vacuum system (and especially on the vacuum
pump), it may be necessary to wear suitable protective clothing,
gloves and a breathing mask depending on the product!
Refer to the separate instruction manual of the vacuum pump and
silencer!
