The main purpose of an O&M Manual is to provide which of the following?

• A. Direction to the owner on how to maintain the system.
• B. Installation instructions for contractors.
• C. Warranty and service terms.
• D. Compliance checklists for inspectors.

Answer: (A)

O&M manuals are written to guide the owner in keeping the system operating safely and effectively over its life. This document consolidates how to operate the system, routine maintenance tasks, preventive maintenance schedules, safety precautions, and troubleshooting steps in one place so the owner can manage upkeep without needing to hunt through scattered notes. That focus on ongoing operation and maintenance is what makes it the best choice. Installation instructions belong with the contractor’s installation documents, not ongoing maintenance guidance. Warranty and service terms are found in separate warranty documents. Compliance checklists are intended for inspectors to verify codes and standards, not for daily maintenance by the owner.
