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. Wait approx. five minutes before restarting the pump.
☞ Attention: In case of supply voltage below 100V, the lock 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 power 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.
