Safety
2.1 Safety precautions
• Do not loosen any plug connection during operations.
• Wait for the rotor to reach standstill before peforming work on the high vacuum
flange.
• Keep leads and cables well away from hot surfaces (> 70 °C).
• Never fill or operate turbopump with cleaning agent.
• Do not carry out any unauthorised modifications or conversions to the pumps.
• The unit has been accredited with protection class IP 20. When installing into
ambient conditions, which afford higher protection classes, the necessary
measures must be taken.
2.2 Proper use
• Only use the pumping station for creating vacuum.
• Only operate the pumping station as an entire unit.
• Only use the pumping station for evacuation of dry and inert gases; other appli-
cations only after consultation with Pfeiffer Vacuum.
2.3 Improper use
Improper use will cause all claims for liability and guarantees to be forfeited. Im-
proper use is deemed to be all use for purposes deviating from those mentioned
above, especially:
• Pumping of corrosive or explosive media.
• Pumping of condensing vapors.
• Operation with improper high levels of gas loads.
• Operation with improper high fore-vacuum pressures.
• Operation with improper gas mode.
• Operation with improper high levels of insulated heat input.
• Venting with improper high venting rates.
• The operation of the devices in potentially radioactive areas.
• The operation of the devices in systems where the turbopumps are subjected to
impact-like stress and vibrations or the effect of periodically occurring forces.
NOTE
Duty to inform
Each person involved in the installation, operation or maintenance of the pumping
station must read and observe the safety-related parts of these operating instuctions
and the components instructions.
Absolute observe the safety information for vacuum pumps (PT 0300 BN) !
The operator is obligated to make operating personnel aware of dangers originating
from the vacuum pump, the pumped medium or the entire system.
NOTE
CE conformity
The manufacturer's declaration of conformity becomes invalid if the operator modifies
the original product or installs additional components.
Following installation into a plant and before commissioning, the operator must
check the entire system for compliance with the valid EU directives and reassess it
accordingly.
