5.1 Delivery and Uncrating of Unit
Inspect equipment and shipping crate immediately upon receipt. If any damage is apparent, you should
discuss it with the trucking delivery person and contact the transportation company immediately. Make notes
of any damage on the Bill Of Lading. Retain all shipping materials for inspection. Any claims for damage
must start at the receiving point. Check packing slip carefully and make sure all materials have been
received as indicated on the packing ticket. Unless otherwise noted, YOUR ORDER HAS BEEN SHIPPED
COMPLETE.
Chambers and any remote machinery skids or control cabinets should be handled and
transported in an upright position. They must never be carried on their back, front, or any side.
Important! Inspect the circulation fan inside the chamber. The fan is driven by a motor that is mounted in
isolation bushings. Sometimes during shipping, the motor is pushed out of vertical alignment. If this has
occurred, the fan blade will strike the casing. Eliminate the interference by pushing the motor back into
alignment on its rubber mounts. However, be sure that the shipping abuse was not so great that the
extension shaft on the fan has been bent.
Important! Do to the vibration incurred during shipping and handling, it is possible that mechanical
connections could become loose. Check all connections to make sure they are secure.
