Serviceability and longevity of the systems?
Provide sufficient service access, both for routine maintenance service, and for repair service. Pay particular attention to space requirements for replacing large components or long parts, such as shafts. Position equipment and access so as to avoid or minimize interruption to normal access. Never position equipment above owners equipment which makes access difficult or impossible. Strictly avoid equipment overhead which might result in damage to products or equipment below. Provide for isolation capability which will facilitate normal repairs or service without interrupting normal operation.
