- Page 13 Safety WARNING Danger of injury from impermissibly high inert gas pressure Increased inert gas pressure compromises the operational reliability due to increasing power con- sumption of the vacuum pump and potentially causes the temperature class threshold to be exceed- ed. There is a danger of bursting if there is a potentially explosive atmosphere. This leads to injuries caused by flying fragments, the escaping of high pressure, and damage to the unit.
- Page 14 Safety WARNING Health hazard through poisoning from toxic contaminated components or devices Toxic process media result in contamination of devices or parts of them. During maintenance work, there is a risk to health from contact with these poisonous substances. Illegal disposal of toxic sub- stances causes environmental damage.

Operation 6.4 Refilling operating fluid WARNING Risk of injury from reactive, potentially explosive or otherwise hazardous gas/air mixtures Uncontrolled exchange of gases when opening the housing could potentially generate a potentially explosive mixture of gas and air in the vacuum system or even outside of the vacuum pump. Ignition can cause very serious injuries. - Page 37 ► Shut off the intake line with an additional shut-off valve, after the vacuum pump is switched off during longer venting operations. Pfeiffer Vacuum rotary vane pumps have an integral vacuum safety valve on the intake side. The vac- uum safety valve automatically closes from a differential pressure of ≥250 hPa between the exhaust and intake sides, when the vacuum pump is switched off, and vents the vacuum pump.
