Oil-sealed vacuum pump and exhaust filter (oil mist separator)
WARNING
Risk of poisoning/infection caused by vacuum pump exhaust gases
The exhaust gases of the vacuum pump may contain harmful substances
originating from the product.
Inhalation may cause severe damage to health.
• Use the freeze-dryer only if it is equipped with a pipe that is properly
connected to the outlet of the vacuum pump/exhaust filter (oil mist
separator) and led to the outside via the roof!
• Depending on the product that is dried in the freeze-dryer, it may be
necessary to install a suitable filter system in the exhaust gas pipe!
• Compliance with the local rules and regulations concerning the
protection of the environment must be ensured!
NOTE
Refer to the separate instruction manual of the vacuum pump and exhaust
filter (oil mist separator)!
The oil mist that escapes when the pump is in operation must be retained
or carried off by way of an exhaust filter (oil mist separator).
• We strongly recommend using an oil mist separator. This filter prevents
air pollution by oil mist that is emitted more or less strongly by the pump
depending on the working pressure.
• Use the freeze-dryer only if it is equipped with a pipe that is properly
connected to the outlet of the oil mist separator and led to the outside
via the roof. The hose must be laid so that the condensate cannot flow
back into the pump. In the case of upward leading hoses, we
recommend using a separator (Woulfe's bottle or wash bottle).
