CAUTION
Danger of injury from bursting as a result of high pressure in the exhaust line
Faulty or inadequate exhaust pipes lead to dangerous situations, e.g. increased exhaust pressure.
There is a danger of bursting. Injuries caused by flying fragments, the escaping of high pressure, and
damage to the unit cannot be excluded.
► Route the exhaust line without shut-off units.
► Observe the permissible pressures and pressure differentials for the product.
► Check the function of the exhaust line on a regular basis.
Condensate separator
Pfeiffer Vacuum recommends installing a condensate separator, with condensate drain at
the lowest point of the exhaust line.
Procedure
1. Check the installed silencer for free passage.
2. Choose a minimum exhaust line diameter equal to the nominal diameter of the connection flange.
3. Depending on the pump type, use PVC or metallic hoses with flange connections from the
4. Option: In case of higher gas throughputs, mount an exhaust line.
5. Route the piping downwards from the vacuum pump, to prevent condensate return.
6. Support or suspend the piping to the vacuum pump so that no piping system forces act on the
vacuum pump.
5.4 Establishing the electric connection
WARNING
Risk of injury due to incorrect installation
Dangerous situations may arise from unsafe or incorrect installation.
► Do not carry out your own conversions or modifications on the unit.
► Ensure the integration into an Emergency Off safety circuit.
5.4.1 Grounding the vacuum pump
Fig. 3:
Connect grounding cable
Procedure
1. Use a suitable grounding cable to divert applicative interferences.
2. Route the connection in accordance with locally applicable provisions.
3. On the vacuum pump, use the designated ground terminal on the fixing plate (M4 female thread).
