WARNING
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!
NOTE
Refer to the separate instruction manual of the vacuum pump and
silencer!
The freeze-dryer is equipped with a dry-running vacuum pump. As a result,
the vacuum exhaust gases are completely free from oil particles. However,
small quantities of debris from worn seals may be emitted. That is why,
even when working with non-harmful substances, the exhaust gases must
either be led to the outside through the roof via a pipe that is properly
connected to the outlet of the vacuum pump, or they must be filtered by
way of a silencer with integrated filter elements that is connected to the
outlet of the vacuum pump.
This freeze-dryer uses a silencer with integrated filter elements. The
silencer is removed for transport and must be installed prior to
commissioning the freeze-dryer:
• Switch the freeze-dryer off.
• Clean the vacuum connector of the freeze-dryer with a cloth.
• Fasten the silencer to the vacuum connector by way of the supplied
centring ring and clamping ring.
