shipping damage. File damage claims
immediately with the delivering carrier.
Check nameplate unit data so that it

the access panel, fan section, or
compressor section. See the
“Receiving and Handling” section on
page 6.
Unit Location
Ensure the unit location is adequate for
unit dimensions, ductwork, piping, and
electrical connections.
Ensure access and maintenance
clearances around the unit are
adequate. See the “Service Access”
section on page 7.
