Warning
Prior to star ng the unit it is important to ensure that the fans are free running, and should
any components have moved during transit take care to ensure they are realigned to allow
correct opera on/rota on. A trial spin by hand should indicate if the fan is rubbing. To align,
loosen the fan inlet eye fixings and adjust the pos on so that the gap between inlet and fan are
equidistant. Ensure the fan runs freely in the new posi on, re ghten the fixings, holding the
inlet eye in pos on see figure above. The same should be applied to any wiring looms
which may have become unfastened; ensure that loose wiring is securely stowed away from
any moving components.
The impellers on EVC0/EVCB0 and EVCB1 units are not adjustable; any alignment issues should
be reported to VES.
