TL;DR
An O&M manual is the operation and maintenance package a contractor turns over at project closeout, compiling equipment manuals, warranty certificates, as-built drawings, paint schedules, filter sizes, and service contacts in one organized set. On commercial work it is a contractual deliverable tied to final payment; on residential projects an equivalent binder or digital folder saves the owner years of guesswork about model numbers and maintenance intervals.
