When unpacking the equipment, carefully inspect the shipping containers as soon as you receive them
(with the delivery agent present). If a container is damaged, open it immediately, inspect the contents,
and have the agent make note on the shipping document. Check the purchase order against the
packing slips to ensure the order is complete.
If the contents of a container are damaged in any way, notify the carrier and your Johnson Controls®
representative immediately. Report any discrepancies to your Johnson Controls representative. Save
the packing materials for possible return shipments.
