Unpacking and Damage
Save all packing material until unit is put into service. This merchandise was
carefully packed and thoroughly inspected before leaving our factory.
Responsibility for safe delivery was assumed by the carrier upon acceptance of the
shipment; therefore, claims for loss or damage sustained in transit must be made
upon the carrier by the recipient as follows:
1. Visible Loss or Damage: Note any external evidence of loss or damage on the
freight bill, or express receipt, and have it signed by the carrier's agent.
Failure to adequately describe such external evidence of loss or damage may
result in the carrier's refusing to honor your damage claim. The form
required to file such claim will be supplied by the carrier.
2. Concealed Loss or Damage: Concealed loss or damage means loss or damage
which does not become apparent until the merchandise has been unpacked
and inspected. Should either occur, make a written request for inspection by
carrier's agent within fifteen (15) days of the delivery date; then file a claim
with the carrier since the damage is the carrier's responsibility.
If you follow the above instructions carefully, we will guarantee our full support
of your claim to be compensated for loss or concealed damage.
DO NOT — FOR ANY REASON — RETURN THIS UNIT WITHOUT
FIRST OBTAINING AUTHORIZATION. In any correspondence to Thermo,
