System design and installation should also, where
applicable, follow information presented in accepted
industry guides such as the ASHRAE Handbooks. The
manufacturer assumes no responsibility for equipment
installed in violation of any code or regulation. The
mechanical installation of the packaged roof top units
consists of making final connections between the unit and
building services; supply and return duct connections; and
drain connections (if required). The internal systems of
the unit are completely factory-installed and tested prior to
shipment.
Units are generally installed on a steel roof mounting
curb assembly which has been shipped to the job site for
installation on the roof structure prior to the arrival of the
unit. The model number shown on the unit's identification
plate identifies the various components of the unit such as
refrigeration tonnage, heating output and voltage.
Carefully inspect the unit for damage including damage
to the cabinetry. Any bolts or screws which may have
loosened in transit must be re-tightened.
In the event of damage, the receiver should:
1. Make notation on delivery receipt of any visible
damage to shipment or container.
