☞ 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 products processed by the pumping system.
Never disassemble the aggregatof the Roots pump but return it to the factory for repair
or maintenance.
➨ Isolate equipment from mains before starting maintenance and wait two min-
utes to allow the capacitors to discharge.
☞ Before starting maintenance vent the system, isolate the pump and other compo-
nents from the vacuum system and the electrical supply. Drain condensate if appli-
cable, avoid the release of pollutants. Allow sufficient cooling of the pump.
Ensure that the pump cannot be operated accidentally. Never operate the pump if
covers or other parts of the pump are disassembled. Never operate a defective or
damaged pump.
☞ Attention: The pump might be contaminated with the process chemicals that have
been pumped during operation. Ensure that the pump is decontaminated before
maintenance and take adequate precautions to protect people from the effects of
dangerous substances if contamination has occurred.
☞ Wear appropriate safety-clothing when you come in contact with contaminated com-
ponents.
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.
The A-weighed emission sound pressure level of the pump does not exceed 70 dB(A).
Measurement according to EN ISO 2151:2004 and EN ISO 3744:1995 with standard
silencer or exhaust tube at outlet.
Ensure that maintenance is done only by suitable trained and supervised techni-
cians. 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.
Comply with local and national safety regulations.
Wear parts have to be replaced regularly. In case of normal wear the lifetime of the
diaphragms and valves is > 10000 operating hours. 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.
