Safety information!
Remove all packing material, remove the protective covers and keep, inspect the
equipment.
If the equipment is damaged, notify the supplier and the carrier in writing within three
days; state the item number of the product together with the order number and the
supplier’s invoice number. Retain all packing material for inspection.
Do not use the equipment if it is damaged.
If the equipment is not used immediately, replace the protective covers. Store the
equipment in suitable conditions.
☞ Read and obey this manual before installing or operating the equipment.
☞ For operation valves and/or vacuum pumps are necessary.
Use the equipment for the intended use only (for generation and measurement of
vacuum).
☞ Obey notes on correct vacuum and electrical connections.
☞ Make sure that the individual components are only connected, combined and oper-
ated according to their design and as indicated in the instructions for use.
Obey national safety regulations and safety requirements concerning the use of
vacuum and electrical equipment.
☞ Equipment must be connected only to a suitable fused and protected electrical
supply and a suitable earth point. Failure to connect the pumping unit to ground
may result in deadly electrical shock.
☞ Check that mains voltage and current conform with the equipment (see rating plate).
☞ Make sure ventilation is adequate if the controller is installed in a housing or if the
ambient temperature is elevated.
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.
The devices are not suitable for applications which involve 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.
☞ In case of residues, aggressive or condensable media install a gas washing bottle,
if necessary.
☞ Position the device and the vacuum line in a way that condensate can not reach the
pressure transducer.
☞ If necessary connect inert gas for venting.
Max. permitted pressure: 2 bar (absolute).
☞ At pressures higher than 1060 mbar the display flashes. Error message ”p Er-
ror ” appears, four beeps.
➨ Immediate pressure relief necessary! Risk of bursting!
Attention: At pressures above 1100 mbar the device does no longer display the cor-
rect pressure values (pressure transducer saturated).
