In case a rigid coupling is used it is necessary to verify the perfect alignment between the motor output
shaft and the machine shaft; the fitment between motor shaft and application’s driven shaft must be
executed so that no radial or axial pre-load is generated: these extra loads reduce the bearings expected
lifetime.
The motor can be assembled horizontally or vertically, with output shaft facing up or output shaft facing
down; in any case there are no special rules to be followed about the positioning of the main hose
connections (inlet and outlet lines), while special rules have to be followed for the drain line connections.
During installation, place first the motor against the machine assembly flange and then
insert and tighten the fixing bolts.
NB: motor positioning obtained as a result of the fixing bolts tightening process might
generate axial and radial loads on the motor shaft that will lead to bearings lifetime
reduction.
