Receiving, Inspection & Unpacking

General Installation

When the equipment is received all items should be carefully checked against the bill of lading to be sure all crates

and cartons have been received. Before accepting delivery, carefully inspect each carton or crate for visible shipping

damage. If any damage is noticed, the carrier should make the proper notation on the delivery receipt acknowledging

the damage. Make notations of all damage on all copies of the bill of lading and have all copies countersigned by

the delivering carrier. The carrier should also fill out a Carrier Inspection Report. The factory Traffic Department should

then be contacted. File claim for damage with the carrier. Physical damage to the unit after acceptance is not the

responsibility of Twin City Fan Companies, Ltd.
Unpack each carton or crate and verify that all required parts and proper quantities of each item have been received.
