Receiving and Handling
Receiving
Upon receiving the product, check to make sure all
items are accounted for by referencing the bill of lading
to ensure all items were received. Notify the carrier if
any damage is noticed. The carrier will make notification
on the delivery receipt acknowledging any damage to
the product. All damage should be noted on all of the
copies of the bill of lading which is countersigned by the
delivering carrier. If damaged upon arrival, file a claim
with the carrier. Any physical damage to the unit after
acceptance is not the responsibility of the manufacturer.
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 representative to arrange
for obtaining missing parts.
Storage
If a kitchen fan control center must be stored prior to
installation, it must be protected from dirt and moisture.
Indoor storage is highly recommended. For outdoor
storage, cover the control package with a tarp to keep it
clean, dry, and protected from UV (ultraviolet) radiation
damage.
Handling
Make sure the equipment does not suffer any heavy
vibration or knocks.
NOTE
Improper storage which results in damage to the unit
will void the warranty.
