Required consumable material
● Screw lock, e.g. Loctite 245 or Loctite 577
Procedure
1. Remove the protective cover from the vacuum connection.
2. Establish the shortest possible pipeline between vacuum pump and vacuum chamber.
3. Choose a minimum diameter equal to the nominal diameter of the vacuum connection.
4. Clean the connection threads.
5. Seal the connection threads with screw lock.
6. Install the piping with pipe components and fasteners from the
.
7. Support or suspend the piping to the vacuum pump so that no piping system forces act on the
vacuum pump.
8. Use a screwing flange, separator or filter from the Pfeiffer Vacuum line of
if necessa-
ry.

WARNING
Danger of poisoning due to toxic process media escaping from the exhaust pipe
During operation with no exhaust line, the vacuum pump allows exhaust gases and vapors to escape
freely into the air. There is a risk of injury and fatality due to poisoning in processes with toxic process
media.
► Observe the pertinent regulations for handling toxic process media.
► Safely purge toxic process media via an exhaust line.
► Use appropriate filter equipment to separate toxic process media.
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.
Installation and operation of accessories
Pfeiffer Vacuum offers a series of special, compatible accessories for its rotary vane
pumps.
● You can find information and ordering options for approved
● Described accessories are not included in the shipment.
Condensate separator
Pfeiffer Vacuum recommends installing a condensate separator, with condensate drain at
the lowest point of the exhaust line.
Required consumable material
● Screw lock, e.g. Loctite 245 or Loctite 577
Procedure
1. Remove the protective cap from the exhaust connection.
2. Choose a minimum diameter equal to the nominal diameter of the exhaust connection.
3. Route the piping downwards from the vacuum pump, to prevent condensate return.
– If an air trap is created in the system then a device for draining condensation water must be
provided at the lowest point.
4. Clean the connection threads.
5. Seal the connection threads with screw lock.
