After attaching the mounting feet, you must note the following in order to avoid stressing and 
deforming the machine. 
●  Ensure that the foot mounting surfaces are aligned in one plane and are parallel to the 
machine shaft. 
●  Post-machine the foot mounting surfaces or use thin shims, for example. 
●  Professionally touch up damaged painted surfaces. 
●  Observe the information provided in Chapter Aligning and mounting (Page 59) 
 
Observe the following when aligning and mounting: 
●  Ensure a flat and uniform contact surface for foot and flange mounting. 
●  When mounting on the wall, support the machine from below, e.g. using a bracket, or bolt 
it. 
●  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.
