Function description
Operation without op-
erating unit
NOTICE
Danger of the pump being destroyed
Pumping of gases with a higher molecular mass in the wrong gas mode can lead to de-
struction of the pump.
Ensure the gas mode is correctly set.
Contact Pfeiffer Vacuum before using gases with a greater molecular mass (> 80).
WARNING
Danger due to open high vacuum flange
The rotor of the turbopump turns at high speed. If the high vacuum flange is open, there
is a danger of cut injuries and that the pump can be destroyed by objects falling into it.
Never operate the pump with an open high vacuum flange.
CAUTION
Automatic start
After bridging the contacts Pin 1, 3, 4, 14 on the connection "
remote
" or using the mating
plug supplied
and
setting up the supply voltage, the turbopump will run up immediately.
Switch on the mains supply on the turbopump immediately before operation.
