►
Never put the device into operation with the high vacuum connection open.
►
Keep lines and cables away from hot surfaces (> 70°C).
►
Never fill or operate the unit with cleaning agents or cleaning agent residues.
►
Do not carry out your own conversions or modifications on the unit.
►
Observe the unit protection class prior to installation or operation in other environments.

Tbl. 3: 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.
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
required maximum fore-vacuum pressure.
►
Use the turbopump only in closed indoor areas.
►
Use the turbopump only for the evacuation of dry and inert gases.
►
Exclusively use C-version turbopumps with sealing gas supply for the pumping of corrosive media.
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.
●
Transport, installation or operation of the vacuum pump in an impermissible spatial position
●
Establishing the voltage supply without correct installation
●
Installing the pump with unspecified mounting material
●
Pumping explosive media
●
