4 Operation
Study the instructions carefully and pay special attention to warnings! Always check the Agitator before operation. Alfa Laval
recommends a soft starter for the Agitator to reduce the load on tank and Agitator.
All position numbers and item numbers refer to the drawings shown and specified in chapter 7 Parts list/Service kits.
NOTE
The Agitator must not be run at temperatures above 90°C.
Ensure that all surfaces in contact with product are totally clean so product is not contaminated and that the Agitator itself is
not exposed pit corrosion.
Pay special attention to:
- Impeller device surfaces.
- Surfaces between propellers and shaft.
- Surfaces around sealing and bushings.
- Surfaces around weldings.
