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.
Step 4
Ensure the impeller device orientation is correct according to the direction of the desired flow. The direction is determined by the
letter "D" or "U" in the last part of the Agitator type description. E.g. -E400D3P has the letter "D" which means the flow direction
is away from the drive unit. -E400U3P has the letter "U" which means the flow direction is towards the drive unit.
Step 5
Ensure the impeller is positioned, keeping minimum radial
distance to the tank.
Further installation requirements regarding the position can
be found in chapter 6.2 Mounting angle for side mounted
Agitator type ALS and chapter 6.3 Mounting angle for
bottom mounted Agitator type ALB to ensure optimum
performance.
