UNPACKING
When receiving the unit, be sure to inspect it carefully for

filing a claim.
When loss or damage is discovered after the equipment
is delivered, but not seen at the time of delivery, it is
referred to as “concealed damage.” Separate any dam-
aged material and contact the carrier for proper proce-
dures to file a “concealed damage” claim.
