Technical data
Ensure that in case of failure, the pump and the vacuum system turn always into a
safe status.
☞ In case of leaks in the manifold or at the shaft seal pumped substances may leak
into the environment or in the pump housing or the motor.
☞ Comply especially with all notes on use and operation and on maintenance.
☞ Failure of the pump (e. g. due to power failure) connected components or parts of
the supply or change of parameters must not lead to a critical dangerous situation
under any circumstances.
Use only oil of the recommended type.
☞ Other oils or operating fluids may cause damage of the pump or danger.
Use special oils (e. g. perfluoropolyether oils) if:
☞ The pump operates in the vicinity of potential ignition sources.
☞ Oxygen or other flammable gases account for a large proportion of the evacuated gases.
Adopt precautionary measures (e. g. wear appropriate safety-clothing and protective
goggles) to avoid excessive contact with the skin and possible skin irritations (includ-
ing dermatitis).
☞ Observe all relevant statutory requirements and regulations concerning the use,
storage and disposal of oil.
Use only genuine spare parts and accessories.
☞ Otherwise safety and performance of the equipment as well as the electromagnetic
compatibility of the equipment might be reduced.
Wear parts have to be replaced regularly. Bearings have a typical durability of 40000
h. Motor capacitors have a typical durability in the range of 10000 to 40000 h depending
strongly on the operation conditions like ambient temperature, humidity or load.
☞ Check every capacitor regularly by measuring its capacity and estimating its opera-
tion time. Exchange old capacitors early enough to prevent a failure. If an overaged
motor capacitor fails it might get hot and even melt and may cause a flame to form
which could be dangerous for persons and equipment in the vicinity. The ca-
pacitors have to be replaced by an electrician.
Ensure that maintenance is done only by suitably trained and supervised technicians.
Ensure that the maintenance technician is familiar with the safety procedures which
relate to the product processed by the vacuum system and that the equipment, if
necessary, is appropriately decontaminated before starting maintenance.
Obey local and national safety regulations.
Before starting maintenance, vent the system, isolate the pump and other compo-
nents from the vacuum system and the electrical supply, drain condensate and allow
sufficient cooling of the pump.
In order to comply with law (occupational, health and safety regulations, safety at work
law and regulations for environmental protection) vacuum pumps, components and
measuring instruments returned to the manufacturer can be repaired only when certain
procedures (see section “Notes on return to the factory“) are followed.
