Change over the voltage range for vacuum pumps with reversible motor
1. The mains voltage must be determined on-site each time before the vacuum pump is installed or
moved to a different location.
2. Disconnect vacuum pump from mains.
3. Set the required voltage range on the voltage selector switch using a suitable screwdriver.
5.5 Filling the operating fluid
WARNING
Danger of poisoning from toxic vapors
Igniting and heating synthetic operating fluid generates toxic vapors. Danger of poisoning if inhaled.
► Observe the application instructions and precautions.
► Do not allow tobacco products to come into contact with the operating fluid.
NOTICE
Risk of damage due to the use of non-approved operating fluid
Product-specific performance data are not achieved. All liability and warranty claims against Pfeiffer
Vacuum are also excluded.
► Only use approved operating fluids.
► Only use other application-specific operating fluids after consultation with Pfeiffer Vacuum.
The type of operating fluid specified, as well as the filling quantity for the entire rotary vane vacuum
pump, are shown on the rating plate. Only the operating fluid used during initial installation is permissi-
ble. Subsequent change is possible only after consultation with Pfeiffer Vacuum.
