Installation
5.3 Alignment and mounting
Observe the following when aligning and mounting:
● Ensure a flat and uniform contact surface for foot and flange mounting.
● Precisely align the machine when couplings are used.
● Ensure that the mounting surfaces are clean and free of any dirt.
● Remove any anti-corrosion protection using white spirit.
● Avoid installation-related resonances with the rotating frequency and twice the
line frequency.
● Note any unusual noise when the rotor is manually turned.
● Check the direction of rotation with the motor uncoupled.
● Avoid rigid couplings.
● Repair any damage to the paint, this must be done immediately and correctly.
