Vacuum pump
NOTE
It is absolutely essential to refer to the separate instruction manual of the
vacuum pump and exhaust filter (if applicable)!
The vacuum pump must be connected to the vacuum connection of the unit
and to the electrical socket at the back of the unit, which is marked
accordingly (see chapter 2.1.1 - "Functional and operating elements").
NOTE
The vacuum pump is supplied with power by the unit, but the maximum
current for the vacuum pump is limited. It is absolutely essential to refer to
the label of the electrical outlet for the vacuum pump (see the following
picture)!
If the current requirement of the vacuum pump is higher than the value
that is stated on the label, the pump must be supplied separately via an
on-site power socket.

The oil mist that escapes from the pump during operation must be retained
or discharged via an exhaust filter (oil mist separator).
• We strongly recommend using an oil mist separator. The filter prevents
air pollution by the oil mist that is emitted more or less strongly by the
pump depending on the working pressure.
• The exhaust gases must be discharged in a proper manner.
• The hose line must be laid in such a manner that any condensation
water cannot flow back into the pump. In the case of a rising hose line,
we recommend using a condensate trap (Woulff bottle or wash bottle).
