placed in operation without fear of damage. All equipment is verified
as ready to run with shipping stops and protective wrap removed,
protective covers in place, surfaces cleaned of construction spatter, ro-
tating parts able to move freely, etc. Valves and dampers are placed
in a normal position; fluid-handling systems have been flushed clean
and pressure-tested. Insulation may or may not be finished, but work
is at least in progress. Control installations are complete and may
have a first-time setup.
With all components essentially there, the commissioning team goes
from one device to the next, verifying basic function. Motors are jogged
to verify rotation; fans and pumps are run for enough time to see that
things are all right, that power is available where needed, and that
automatic valves and dampers will stroke.
The first run does not require calibration or test of capacity or ad-
justment. It merely confirms that the systems are intact, ready for
tuneup and test by the specialist.
