Conditions of use
The vacuum pumps TOPAS D004 V - D041 V are designed for use in the commer-
cial sector, i.e. the safety equipment corresponds to DIN EN ISO 13857 table 4 for
people aged over 14 years.
The TOPAS D004 V - D041 V is suitable for the evacuation of closed systems or
for a permanent vacuum in the following suction pressure ranges:
TOPAS D004 V - D008 V:
2 to 200 mbar (abs.)
TOPAS D012 V - D020 V:
2 to 400 mbar (abs.)
TOPAS D026 V - D041 V:
0,5 to 400 mbar (abs.)
For continuous operation outside of these ranges, there is a risk of oil loss
through the outlet opening. For evacuation of closed systems, the volume to be
evacuated may only be such that the maximum intake pressure can be achieved
in a few seconds.
The dependency of the suction power on the suction pressure is type-specific and
can be taken from the corresponding datasheets:

The suctioned air may contain water vapour, but no water or other fluids. Ag-
gressive or combustible gases and vapours may not be suctioned. No hazardous
additives (e.g. combustible or explosive gases or vapours) or aggressive gases
may be suctioned.
Operation in rooms with an explosion risk is not permitted.
The ambient temperature must be between 12°C and 40°C, and the suction tem-
perature must be between 5°C and 40°C. For temperatures outside of this range,
the manufacturer should be consulted.
Counterpressures on the outlet side are only permitted up to + 0.1 bar.
NOTICE!
In application cases in which an unplanned shutdown or failure of the vacuum
pump can cause harm to persons or equipment, appropriate safety measures
must be taken on the equipment side.
