Receiving, Inspection, Unpacking, Storage, Assemblies

Receiving and Inspection
Upon receiving the product, verify that all pieces listed on the bill of lading, delivery receipt, or packing list have been received.
Inspect each crate or carton for shipping damage before accepting delivery. Alert the carrier if any damage is detected; do not refuse
shipment. The customer must note any damage (or shortage of items) on the delivery receipt and all copies of the bill of lading, which then
should be signed by the delivery carrier. Photograph the damage if possible. If damaged, immediately contact your manufacturer's represen-
tative.
Any physical damage to the unit after acceptance is not the manufacturer's responsibility.
Handling
Handle in such a manner as to keep from scratching or chipping the unit. A damaged finish may reduce ability of unit to resist corrosion.
Unpacking
Verify that all required parts and the correct quantity of each item have been received. If any items are missing, report shortages to your local
manufacturer's representative to obtain the missing parts. Confirmation of shipment(s) must be limited to only the items on the bill of lading.
Storage
Units are protected against damage during shipment. If the unit cannot be installed and operated immediately, precautions need to be taken
to prevent deterioration of the unit during storage. The user assumes responsibility of the unit and accessories while in storage. The manu-
facturer will not be responsible for damage during storage. These suggestions are provided solely as a convenience to the user.
The ideal environment for storing the units and accessories designed for indoor applications is indoors, above grade, in a low humidity at-
mosphere that is sealed to prevent dust, rain, or snow from entering. Units designed for outdoor applications may be stored outdoors, but all
accessories must be stored indoors in a clean, dry atmosphere.
Removing from Storage
As units are removed from storage to be installed in their final location, they should be protected and maintained in a similar fashion until
the equipment goes into operation. Before installing the unit and system components, inspect the unit assembly to make sure it is in working
order:
1. Check all fasteners, set screws on the fan, wheel, bearings, drive, motor base, and accessories for tightness.
2. Rotate the fan wheel(s) by hand to ensure parts are not in contact with one another and are causing friction / damage.
