5.1 Setting up vacuum pump
CAUTION
Risk of injury from loss of stability
During setup, there is a risk of injury from tipping, if the vacuum pump is not anchored on the stand-
ing surface.
► Secure the vacuum pump using suitable lifting gear.
► Wear personal protective equipment.
General notes for the installation of vacuum components
► Choose an installation location that permits access to the product and to supply lines at all times.
► Observe the ambient conditions given for the limits of use.
► Provide the highest possible level of cleanliness during assembly.
► Ensure that flange components during installation are grease-free, dust-free and dry.
Procedure
1. Check the carrying capacity of the floor at the installation location.
2. Place the vacuum pump on a flat, horizontal and fixed surface, to safeguard the lubricant supply.
– Reference surface is the vacuum flange.
3. Evenly screw the 4 feet of the vacuum pump onto the base without distorting the pump housing.
4. Use adjustment elements from the Pfeiffer Vacuum
range of accessories for roots pumps
to
mount the feet horizontally.
5. When installing the pump in a closed housing, ensure adequate air circulation.
6. Keep both sight glasses freely accessible for checks and maintenance.
7. Keep the filling/drain holes freely accessible.
8. Ensure that the motor rating plate remains accessible at all times for a clear view of the voltage
and frequency specifications.
9. Maintain the minimum distances to bordering surfaces to guarantee sufficient air circulation.
10. Fill with lubricant prior to first commissioning.
5.2 Filling up lubricant
WARNING
Danger of poisoning from toxic vapors
Igniting and heating synthetic lubricants generates toxic vapors. Danger of poisoning if inhaled.
