It is very important that the machine shall be installed property.
Misalignment, distortion of the bedplate or other errors of this kind may later bring about serious operation troubles even though the unit appears to run satisfactory at first.
It is desirable to have the bedplate as nearly level as possible, but in any case it is absolutely necessary to have the rotating shafts in proper alignment as determined by the couplinga, regardless of the levels.
In order to emphasize this point, the unit is shiped from the factory with the coupling bolts removed.
It is of the utmost importance that the machine be installed so as to have the correct alignment at the coupling faces before installing these bolts or attempting to operate the turbine.
Do not depend upon the stiffness of the bedplate to have maintened the alignment during transit from the factory.
In cases where the coupling is provided by the manufactured of the driven apparatus and the driving half is to be mounted on the turbine shaft in the field, the coupling hub should be carefully heated and shrunk onto the turbine shaft.
Use a gas-ring or a heating coil. Do not use a blow torch and do not overheat. Do not attempt to drive the coupling on with a hammer.
