Receiving Unit
When received, the unit should be checked
for damage that might have occurred in
transit. If damage is found it should be noted
on the carrier’s Freight Bill. A request for
inspection by carrier’s agent should be made
in writing at once.
Nameplate should be checked to ensure the
correct model sizes and voltages have been
received to match the job requirements.
If repairs must be made to damaged goods,
then the factory should be notified before
any repair action is taken in order to protect
the warranty. Certain equipment alteration,
repair, and manipulation of equipment
without the manufacturer’s consent may
void the product warranty. Contact the
AAON Warranty Department for assistance
with handling damaged goods, repairs, and
freight claims: (903) 236-4403.
Note: Upon receipt check shipment for
items that ship loose such as filters and
remote sensors. Consult order and shipment
documentation to identify potential loose-
shipped items. Loose-shipped items may
have been placed inside unit cabinet for
security. Installers and owners should secure
all doors with locks or nuts and bolts to
prevent unauthorized access.
The warranty card must be completed in full
and returned to AAON not more than 3
months after unit is delivered.
