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 temperatureswithoutair.
Thepumpsarenot suitable topumpself inflammable substances,substances which
areinflammable withoutairandexplosive substances.
The pumps are not suitable for pumping dust and have no approval for operation
belowground.
☞Adoptsuitable measuresto preventthe releaseofdangerous, 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
appropriatesafety-clothing andsafety 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 protectpump andenvironment(people).
☞Observethe reagentmanufacturer´sinformation.
☞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 thepump mightrestart on its own aftersufficient cooling down.Take
suitable precautions, if an automatic restart of the pump may lead to a critical
dangeroussituation.
☞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
theenvironment.
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.
☞Incase ofdiaphragm cracksor leaksin themanifold pumpedsubstances mightbe
releasedinto theenvironmentor intothe pumphousing.Toreduce theriskof leaks,
askfor adiaphragm pumpwith additionalsafety diaphragm.
☞Obeyespecially noteson operationand useand maintenance.
☞Failureof thepump (e.g.due topowerfailure)mustnot leadto acritical dangerous
situation under any circumstances.
Useonly genuine spare parts and accessories.
☞Otherwisesafety andperformanceof theequipment aswellas theelectromagnetic
compatibility of the equipment might be reduced.
Possibly the CE mark or the C/US conformity becomes void if not using genuine
spare parts.
