2.5 Proper use
► Use the turbopump only for generating vacuum.
► Use the turbopump only in combination with a suitable backing pump that can deliver up to the
► Use the turbopump only in closed indoor areas.
► Use the turbopump only for the evacuation of dry and inert gases.
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 improper use; in particular:
● Establishing the voltage supply without correct installation
● Installing with non-specified fastening material
Permissible ambient conditions
Notes on ambient conditions
The specified permissible ambient temperatures apply to operation of the turbopump at
maximum permissible backing pressure or at maximum gas throughput, depending on the
cooling type. The turbopump is intrinsically safe thanks to redundant temperature monitor-
ing.
● The reduction in backing pressure or gas throughput permits operation of the turbo-
pump at higher ambient temperatures.
● If the maximum permissible operating temperature of the turbopump is exceeded, the
electronic drive unit first reduces the drive output and then switches it off where neces-
sary.
