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.
Refer to drawings for part descriptions. Report shortages or missing items to your local representative to arrange for
replacement parts.
Due to availability of carriers and truck space, it is not possible to guarantee that all items will be shipped together.
Verification of shipments must be limited to only those items on the bill of lading.
The unit nameplate must be checked to make sure the voltage agrees with the power supply available.
