Considerations for component disassembly

All components must be able to be dissembled quickly, easily
and safely while the unit is operating in the field. To meet this
requirement, sufficient space around the auxiliary console
must be available for such exercises as cooler bundle removal,
filter cartridge removal and auxiliary or main driver removal.
In addition, consoles are frequently installed in congested
areas, and lifting arrangements should be reviewed beforehand
to confirm that components can be removed in a safe and easy
