☞ Ensure that the system design does not allow the exhaust pipeline to become
blocked.
☞ Max. permitted pressure at the pressure transducer: 1.5 bar (absolute).
☞ Check the overpressure safety relief device at the exhaust waste vapour condenser
in appropriate intervals.
☞ Avoid overpressure 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.
☞ Check liquid level in both catchpots regularly and drain condensate in time.
To the best of our knowledge the equipment is in compliance with the requirements of
the applicable EC-directives and harmonized standards (see “Declaration of conform-
ity”) with regard to design, type and model, especially directive IEC 1010. This directive
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.
Pay 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 are not suitable to pump dangerous or explosive gases or explosive or
flammable mixtures. Ensure that the materials of the wetted parts are compatible
with the pumped substances, see section “Technical data”.
☞ Adopt suitable measures to prevent the release of dangerous, explosive, corrosive
or polluting fluids.
☞ Use inert gas for gas ballast if necessary.
☞ The user must take suitable precautions to prevent any formation of explosive
mixtures in the pump. 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, wear appropriate safety-clothing.
☞ Comply with applicable regulations when disposing of chemicals. Take into consid-
eration that chemicals may be polluted.
The motor is protected by a temperature sensor at the circuit board: Current limita-
tion if the temperature at the circuit board is higher than 70°C, switching off the pump
if the temperature is higher than 85°C. In case of bockade of the motor (after 10 at-
tempts to start-up) the pump is switched off.
☞ If the pump is switched off due to safety measures, manual reset is necessary.
Isolate the pump from mains. Eliminate cause of failure before restarting the pump.
☞ 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.
Pumping at high inlet pressure may lead to overpressure at the gas ballast valve.
☞ Pumped gases or condensate might be pushed out if the valve is open.
☞ If an inert gas supply is connected, ensure that the inlet pipeline is not contami-
nated.
