3 Installation
Study the instructions carefully and pay special attention to the warnings!
Always check the Agitator before operation - see chapter 3.3 Pre-use check.
The Agitator is for permanent fastening.
Make sure that the motor correspond to the environment.
Guidelines for installing Flat Shaped Welding Flange (FSWF), ALB Agitator:
(for mounting flange with nose)
CAUTION
Alfa Laval recommend that all other welding tasks on the tank are finished before installing welding flange in tank.
ALB Agitator must be installed in the tank as shown in chapter 6.3 Mounting angle for bottom mounted Agitator type ALB
which can be achieved as shown on the illustration below.
In case of installation of Welding Flange parallel to tank bottom surface (shaft perpendicular to tank bottom surface) it is always
recommended to use a bead/cone. This is to ensure that tank bottom stresses / forces are not transmitted directly to the
Welding Flange increasing the risk of leakages.

CAUTION
Ensure that no weldings are applied to the outside surface of the welding flange* as the Agitators mounting flange has the same
size as the welding flange. If weldings by mistake are applied to the surface of the welding flange it must be removed by grinding,
or the like, to ensure a correct fit and installation of the mounting flange.
