☞ If the equipment is brought from cold environment into a room for operation, allow
the equipment to warm up (pay attention to water condensation on cold surfaces).
☞ Make sure ventilation is adequate if pump is installed in a housing or if ambient
temperature is elevated.
Comply with all relevant safety requirements (regulations and guidelines) and adopt
suitable safety measures.
☞ Provide a firm level platform for the equipment and check that the system to be
evacuated is mechanically stable and that all fittings are secure.
Attention: Flexible elements tend to shrink when evacuated.
Due to the high compression ratio of the pumps, pressure at the outlet port might be
generated being higher than the max. permitted pressure compatible with the mechanical stability of the system.
☞ Comply with maximum permitted pressures and pressure differences, see sec-
tion ”T echnical data”. Do not oper ate the pump with overpressure at the inlet.
Do not permit any uncontrolled pressurizing (e. g. make sure that the exhaust pipeline cannot become blocked). If you have an exhaust-isolation valve, make sure that
you cannot operate the equipment with the valve closed. Risk of bursting!
☞ Avoid o verpressure of more than 0.2 bar in case inert gas is connected.
☞ The diameter of the inlet and outlet pipeline should be at the least as large as the
diameter of the pump connection pipelines.
Maximum liquid level in collecting bottle: approx. 80 %, depending on the application
(in case of low boiling liquids or in case of suction of liquids which tend to foam, the
maximum liquid level might be reduced).
T o the best of our knowledge the equipment is in compliance with the requirements of
the applicable EC-directives and harmonized standards (see ”Declaration of conformity”) with regard to design, type and model, especially directive IEC 1010. This directiv e
gives in detail conditions, under which the equipment can be operated safely (see also
IP degree of protection).
☞ Adopt suitable measures in case of differences, e. g. using the equipment outdoors,
installation in altitudes of more than 1000 m above mean sea level, conductive
pollution or dewiness.
Pa y attention to symbol ”hot surfaces” on the equipment.
☞ Adopt suitable measures to prevent any danger arising from the formation of hot
surfaces or electric sparks.
The pumps have no approval for operation in or for pumping of potentially explosive atmospheres.
If pumping different substances, purge the pump with inert gas prior to changing the
pumped media in order to pump out residues and to avoid reactions of the pumped
substances with each other with and the pump material. Ensure that the materials of
the wetted parts are compatible with the pumped substances, see section ”Technical
data”.
T ake into consideration interactions and chemical reactions of the pumped media.
The pumps are not suitable for pumping substances which may form deposits inside
the pump.
☞ If there is a danger of the formation of deposits in the pump chamber (check inlet
and outlet of the pump) inspect the pump chamber regularly and clean if necessary.

The pumps are not suitable to pump unstable substances and substances which
react explosively under impact (mechanical stress) and/or when being exposed to
elevated temperatures without air .
The pumps are not suitable to pump self inflammable substances, substances which
are inflammable without air and explosive substances.
The pumps are not suitable for pumping dust and have no approval for operation
below ground.
☞ Adopt suitable measures to prevent the release of dangerous, explosive, corrosive
or polluting fluids.
☞ The user must take suitable precautions to prevent any formation of explosive
mixtures in the expansion chamber or at the outlet. In case of a diaphragm crack,
mechanically generated sparks, hot surfaces or static electricity may ignite these
mixtures.
☞ Take adequate precautions to protect people from the effects of dangerous sub-
stances (chemicals, thermal decomposition products of fluoroelastomers), wear
appropriate safety-clothing and safety glasses.
☞☞
☞ Use appropriate safety work materials and methods if necessary , e. g. steam
☞☞
sterilization, sterilization indicators or germicides.
☞ Use the system only in combination with the integrated hydrophobic filter (steriliz-
able) to protect pump and environment (people).
☞ Observe the reagent manufacturer´s information.
☞ Obey applicable regulations when disposing of chemicals. Take into consideration
that chemicals may be polluted.
The motor is shut down by a thermal cutout in the winding.
☞ Attention: Manual reset is necessary . Switch off the pump or isolate the equipment
from mains. W ait appro x. five minutes bef ore restarting the pump.
☞ Attention: In case of supply v oltage below 100V, the loc k of the cutout might be
restricted and the pump might restart on its own after sufficient cooling down. Take
suitable precautions, if an automatic restart of the pump may lead to a critical
dangerous situation.
☞ Avoid high heat supply (e . g. due to hot process gases).
☞ Ensure sufficient air admittance if pump is installed in a housing.
Due to the residual leak rate of the equipment, there may be an exchange of gas,
albeit extremely slight, between the environment and the vacuum system.
☞ Adopt suitable measures to prevent contamination of the pumped substances or
the environment.
Ensure that in case of failure the pump and the vacuum system always will turn into a
safe status.
Never operate a defective or damaged device.
☞ Check collecting bottle for fissures regularly. Do never use a collecting bottle
with fissures nor expose it to vacuum.
☞ In case of diaphragm cracks or leaks in the manifold pumped substances might be
released into the environment or into the pump housing. To reduce the risk of leaks,
ask for a diaphragm pump with additional safety diaphragm.
☞ Obey especially notes on operation and use and maintenance.
☞ Failure of the pump (e . g. due to pow er failure) must not lead to a critical dangerous
situation under any circumstances.
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.
Possibly the CE mark or the C/US conformity becomes void if not using genuine
spare parts.

Notes concerning the sterilization of wetted parts (see ”Technical data”) see section
”Cleaning and decontaminating”.
☞☞
☞ It is the user´s responsibility to ensure effective sterilization.
☞☞
The A-weighted 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 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 bef ore 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.
☞ 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 capacitors have to be replaced by an electrician.
➨ Isolate equipment from mains and wait two minutes before starting mainte-
nance to allow the capacitors to discharge.
☞ Attention: The pump might be contaminated with process chemicals which 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.
☞ 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.
☞ Before starting maintenance vent the pump and allow sufficient cooling of the pump .
Drain condensate, if applicable.
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.
