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.
Welding procedure FSWF, ALB Agitator:
(for mounting flange with nose)
NOTE
Alfa Laval recommend a welding tool with, if possible, build in cooling by flowing water, to be made and fixed to the FSWF to
ensure shape and form of the FSWF during welding and installation.
In general Alfa Laval recommend to weld the welding flange onto a bended rim of the tank bottom plate – this is to secure
adequate flexibility at high loads, e.g. when the tank is filled. If a bended rim is impossible to obtain due to a high plate
thickness, Alfa Laval recommend to weld the welding flange onto a cone shaped plate section.
If not following the above recommendations there will be a risk that the flange can deform, especially at high tank fillings, which
can cause a leakage between the welding flange and the Agitator mounting flange.
Step 1
Position the flange correctly.
Always allow flange to cool to ambient temperature after each section has been welded.
Step 2
Spot weld from outside.
