6 Operation
6.1 Putting the vacuum pump into operation
WARNING
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.
WARNING
Tilting danger! Serious injury due to tilting of the product
There is a danger of the vacuum pump not attached tipping over due to changes in the center of
gravity or incorrect loading. Serious injuries due to trapping or crushing of limbs, e.g. feet, are the re-
sult.
► Do not use the vacuum pump as a climbing aid.
► Do not exert any force on the product.
► Ensure that the product has a safe centre of gravity, when mounting components.
► Wear protective equipment , e.g. protective shoes
CAUTION
Danger of injury from bursting as a result of high pressure in the exhaust line
Faulty or inadequate exhaust pipes lead to dangerous situations, e.g. increased exhaust pressure.
There is a danger of bursting. Injuries caused by flying fragments, the escaping of high pressure, and
damage to the unit cannot be excluded.
► Route the exhaust line without shut-off units.
► Observe the permissible pressures and pressure differentials for the product.
► Check the function of the exhaust line on a regular basis.
Before switching on
1. Check the operating fluid in the sight glass.
2. Compare the voltage and frequency specifications on the motor rating plate with the available
mains voltage and frequency.
3. Protect the vacuum pump from sucking in contamination using suitable measures.
4. Check the operating fluid at regular intervals.
5. Check the exhaust connection for free passage (max. permissible pressure: atmospheric pres-
sure).
6. Open the cooling water supply.
6.2 Switching on the vacuum pump
WARNING
Risk of burns from ejected hot oil mist
During operation, hot pressurized oil mist escapes from the operating fluid separator.
► Only operate the vacuum pump with the filler screw securely fitted.
► Open the locking screws on the separator only while the vacuum pump is switched off.
