Delivery Inspections & Electrical Requirements, Continued

:

Packaging: Your Air Curtain Refrigerator is shipped from the factory on a wood pallet and packaged in a durable cardboard container. The carton 
is attached to the wooden skid with the use of large stables. These should first be removed to avoid scratching the unit when lifting off the crate. 
Remove the wooden pallet and strapping material, and the unit should be rolled off the skid. Avoid laying the unit on its front, side or back for 
removal of the pallet.

Note: Cambro does not recommend laying the unit down on its front, side or back. However, if you must, please be certain to allow the unit to remain 
in an upright position afterwards for 48 hours before plugging the unit in or attempting to place the unit in to service, to assure that the compressor 
oils and refrigerant may settle.
