### The startup report, with the commissioned approaches and operating conditions recorded on it, shall be placed in the operation and maintenance manual.
### That single page answers most future questions about the machine. Every judgment an operator or a service technician later makes about whether a chiller has degraded is a comparison against the day it was known to be right, and without the commissioned baseline the comparison is against a catalog rating taken at conditions the building never sees. {note}
