0.1 Mechanical hazards
WARNING: EJECTION OF PARTS
If the mounting is not sturdy enough, pump blockage could cause the pump to break loose;
internal pump components could be thrown in all directions.
Mount the pump firmly to the vacuum chamber. Never operate the pump without proper flanging
to the vacuum chamber (in bench testing, for example).
In case of rotor destruction a sudden twisting of the entire pump is possible. The vacuum cham-
ber must be able to absorb the torque of max. 10 kNm around the rotor‘s axis of rotation in the
event of sudden rotor destruction.
CAUTION: CUTTING AND CRUSHING
When reaching into open flanges there is a risk of cutting and crushing your fingers.
Do not operate the vacuum pump with open flanges. Do not reach into the pump.
When installing the vacuum pump, first mechanically connect the inlets and outlets and then
make the electrical connections.
Disconnect the vacuum pump from the power supply before servicing. Only use trained service
personnel.
Before servicing, ensure that gas cannot flow through the pump. Only open the pump system
when it is under atmospheric pressure.
CAUTION: EJECTION OF PARTS
Ejection of parts through bursting of vacuum system as a result of excessive pressure.
When using the pump with purge gas, protect the purge gas supply such that in the event of a
malfunction no overpressure can occur within the system. The pressure in the pump must not
exceed 1.4 bar (absolute).
CAUTION: VACUUM
Pulling into the vacuum can cause injury to hands or fingers.
Do not operate the vacuum pump with open flanges.
CAUTION: FALLING PARTS
Errors during transport can cause the pump to fall down.
Transport the pump only in its transport packaging or at the eye-bolts provided for this purpose.
