Limits of use for turbopump stations
Notes on ambient conditions
The specified permissible ambient temperatures apply to operation of the turbo-
pump at maximum permissible backing pressure or at maximum gas throughput,
depending on the cooling type. The turbopump is intrinsically safe thanks to redun-
dant temperature monitoring.
● The reduction in backing pressure or gas throughput permits operation of the
turbopump at higher ambient temperatures as well.
● If the maximum permissible operating temperature of the turbopump is exceed-
ed, the electronic drive unit first reduces the drive output and switches it off
where necessary.
2.5 Proper use
● The turbo pumping station is only used to generate the vacuum.
● The turbo pumping station is only used to extract dry and inert gases.
● The turbo pumping station is only intended for use in enclosed interior spaces.
● The turbo pumping station is intended for use as a table-top unit.
2.6 Foreseeable improper use
Improper use of the product invalidates all warranty and liability claims. Any use that is counter to the
purpose of the product, whether intentional or unintentional, is regarded as misuse, in particular:
● Establishing the voltage supply without correct installation
● Installation with non-specified fastening material
● Pumping explosive media
● Pumping of corrosive media
● Pumping of condensing vapors
● Pumping of fluids
● Pumping of dust
● Operation with impermissible high gas throughput
● Operation with impermissible high fore-vacuum pressure
● Operation with excessively high irradiated heat output
● Operation in impermissible high magnetic fields
● Operation in an incorrect gas mode
● Venting with impermissible high venting rates
● Use for pressure generation
● Use in areas with ionizing radiation
● Operation in explosion-hazard areas
● Use in systems in which sporadic loads and vibrations or periodic forces act on the device
● The causing of hazardous operating conditions by a presetting on the electronic drive unit that is
contrary to the process
● Use of accessories or spare parts that are not listed in these instructions
