2.3Equipment Inspection upon receipt

When the unit arrives, do not uncrate equipment until it is close to its final location. All required assemblies are banded and shipped in corrugated containers. If you discover any damage when you uncrate the unit, report it to the shipper immediately. If you later find any concealed damage, report it to the shipper and to your Liebert supplier.
