Receiving
Upon receiving the equipment, check for both obvious

necessary information on the bill of lading and file a
claim with the final carrier. If any items are missing,
report shortages to your local representative to arrange
for obtaining missing parts. Confirmation of shipment(s)
must be limited to only items on the bill of lading. Any
physical damage to the unit or missing parts found after
acceptance is not the responsibility of the manufacturer.
Handling
Move the unit slowly and carefully using the forklift
pockets on either end. Be sure to completely support
the entire unit length when moving. Do not lay the
crated unit on its side.
Storage
Units are protected against damaged during shipment.
If the unit cannot be installed and operated immediately,
precautions need to be taken to prevent deterioration of
the unit during storage. The user assumes responsibility
of the unit and accessories while in storage.
The ideal environment for storage of the UDS and
accessories is indoors, above grade in a clean, dry
atmosphere that is sealed from the elements. Store unit
standing up; do not lay the unit on its side.
