Correct Use; Useful Information - IKA Vacstar digital Betriebsanleitung

Use
The device must not be used for:
WARNING
- evacuating biological habitats,
- evacuating explosive, corrosive
- throughput/use of liquids
The device is not suitable for:
- pumping up objects
- pumping liquids
- use in potentially explosive
- underwater
- underground
The laboratory diaphragm vacuum pump IKA Vacstar digital is used
together with other laboratory devices to create a vacuum.
For specific vacuum control, an additional vacuum controller IKA
VC 10 or IKA rotary evaporator RV 10 auto is required.
Area of use (only indoors)
The device is suitable for use in residential areas and all other
areas.
The safety of the user cannot be ensured:
• if the device is used in conjunctions with accessories not
made or recommended by the manufacturer!
You can prevent the release of

solvent vapours into the atmosphere
using a downstream emission
condenser.
Special care must be taken when
CAUTION
working with gas mixtures that
include condensable gases (e.g.
solvents). If diaphragm pumps are
used with such gases they condense
in the pump's air flow. This leads
to a build-up of pressure in the
vacuum chamber, which in turn
influences the effectiveness and
service life of the diaphragms and
valves.
If liquid or condensate enters the
vacuum chambers, the specified
minimum working pressure is no
longer achieved.
To protect the inner valves and
diaphragms against liquid, use an
upstream condensate separator,
such as a Woulff bottle.

Correct use

Standalone operation
The vacuum pump can be operated without a controller.
The delivery capacity can be set using the adjustable speed.
Generally speaking, the smaller the volume to be evacuated, the
lower the speed should be. The final pressure is not controlled.
Operation with accessories
Along with the accessories recommended by IKA, the vacuum
pump IKA Vacstar digital is suitable for controlled evacuation to a
specified final pressure e.g. for operating an IKA rotary evaporator.
It can also be used for classical separation, filtration or drying in
the laboratory.
With an appropriate vacuum controller (e.g. VC 10) or with a ro-
tary evaporator (e.g. RV 10 auto), the Vacstar digital can be oper-
ated automatically, for automatic boiling point detection, sched-
uled pressure-time curves or programs from the solvent library, for
example.
Intended use: Tabletop device
• if modifications are made to the device or parts of the device
by third parties!
• if the device is operated in contravention of the safety
instructions!
CAUTION
NOTE
Diaphragm vacuum pumps are oscillating displacement pumps.
The diaphragms expand the volume of the vacuum chamber to
produce an underpressure, which sucks air into the chamber. The
air is then pressed out of the vacuum chamber by subsequent
compression. Changes between the inlet and outlet are controlled
by diaphragm valves.
The physical unit for pressure is 1 Pascal [Pa].
However people often still use the unit millibar [mbar] colloquially.
1 mbar = 100 Pa
1 bar = 10 5
1 Pa = 10 -5
1 Pa = 0.01 mbar
It is generally recommended that
you run the pump with no load at
the end of the process (no-load
operation, approx. 3 up to max. 5
minutes) to dispel any residues in
the pump.
If applicable, vent the recipient.
To do this, remove the suction line
during manual operation.
Observe the operating instructions
of the relevant devices.
