Section 1 - Receiving
1.1 Preliminary Inspection
This item was thoroughly inspected and carefully packed
prior to shipment. All necessary precautions were taken to
ensure safe arrival of the merchandise at its destination.
Immediately upon receipt, before the unit is moved from the
receiving area, carefully examine the shipment for loss or dam-
age. Unpack the shipment and inspect both interior and exterior
for any in-transit damage.
1.2 Visible Loss or Damage
If any loss or damage is discovered, note any discrepancies
on the delivery receipt. Failure to adequately describe such evi-
dence of loss or damage may result in the carrier refusing to
honor a damage claim. Immediately call the delivering carrier
and request that their representative perform an inspection. Do
not discard any of the packing material and under no circum-
stances, move the shipment from the receiving area.
1.3 Responsibility for Shipping Damage
For products shipped F.O.B. Marietta, Ohio, the responsi-
bility of Thermo Electron Corporation ends when the merchan-
dise is loaded onto the carrier’s vehicle.
On F.O.B. Destination shipments, Thermo and the carrier’s
responsibility ends when your Receiving Department personnel
sign a free and clear delivery receipt.
Whenever possible, Thermo will assist in settling claims
for loss or in-transit damage.
