OVEN RECEIPT & HANDLING
Receiving Inspection
A complete inspection of the oven should be conducted and any discrepancies noted. Shipping indicators,
(see examples below), are mounted to the inside of the oven before shipping from the factory. These
indicators should be checked and the “as received” condition recorded as part of the receiving inspection
process. If the oven shipping crate/packaging shows any signs of damage or rough handling, a notice should
be filed with the shipper at the time of receipt.
