Final Alignment
The procedures and tolerance requirements for final alignment are the same as those de-
scribed in the Near Final Alignment section. Final alignment is performed just prior to grouting
and machine hot check. All piping, including water and steam, must be completed, but the water
and refrigerant charges need not be in place.
Hot Alignment Check
General
When all machine components have reached operating temperature (after running near full
load for from 4 to 8 hours), a hot alignment check must be made. Hot alignment check may be
made with couplings assembled or disassembled.
