B52. All appliances must be electrically
grounded in accordance with local codes, or
in the absence of local codes, the current
National Electric Code, ANSI/NFPA 70 or
the current Canadian Electrical Code CSA
C22.1.
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-Longview 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
Failure to observe the following
instructions will result in premature
failure of your system and possible
voiding of the warranty.
The Clean Air Act of 1990 bans the
intentional venting of refrigerant as of
