Operation
6 Operation
6.1 Commissioning vacuum pump
Before switching on
1. Check the lubricant levels on both sight glasses.
2. Compare the specifications on the motor rating plate with the available mains voltage and fre-
3. Make sure that the suction chamber is free from all foreign matters.
4. Check the vacuum pump for visible damage and put the vacuum pump into operation only in a
5. Protect the vacuum pump from sucking in contamination using suitable measures (e.g. dust filter).
6. Make sure that the shut-off units on the pressure side open before starting the pump.
6.2 Switching on vacuum pump
Danger of poisoning due to toxic process media escaping from the exhaust pipe
During operation with no exhaust line, the vacuum pump allows exhaust gases and vapors to escape
freely into the air. There is a risk of injury and fatality due to poisoning in processes with toxic process
media.
► Observe the pertinent regulations for handling toxic process media.
► Safely purge toxic process media via an exhaust line.
► Use appropriate filter equipment to separate toxic process media.
Danger of burns on hot surfaces
Depending on the operating and ambient conditions, the surface temperature of the vacuum pump
can increase to above 70 °C.
► Provide suitable touch protection.
Procedure for operation without FC
1. Allow the vacuum pump to warm up with the vacuum flange closed, for approx. 30 minutes prior to
2. Do not switch on the roots pump until the fore-vacuum pressure allows the backing pump to ac-
3. Switch off the roots pump immediately if the backing pump fails.
Procedure for operation with FC
1. Allow the vacuum pump to warm up with the vacuum flange closed, for approx. 30 minutes prior to
2. If you wish to switch on the roots pump simultaneously with the backing pump, use a frequency
6.3 Check the lubricant level
Check the lubricant level
1. Regularly check the lubricant level while the vacuum pump is running and at operating tempera-
