5.5.1
Oil-sealed vacuum pump and exhaust filter (oil mist separator)
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. Alternatively, it can be connected to the freeze-dryer
via an interface box (see chapter 5.6 - "Use of an interface box").
