INSPECT SHIPMENT
Do not open any valves or break any connections. The standard 23XL machine is shipped with a full refriger- ant charge. Some machines may be shipped with a nitrogen holding charge as an option.
1.Inspect for shipping damage while the machine is still on shipping conveyance. If the machine appears to be dam- aged or has been torn loose from its anchorage, have it examined by transportation inspectors before removal. For- ward claim papers directly to the transportation com- pany. The manufacturer is not responsible for any dam- age incurred in transit.
2.Check all items against shipping list. Immediately notify the nearest Carrier representative if any item is missing.
3.To prevent loss or damage, leave all parts in original pack- ages until installation. All openings are closed with covers or plugs to prevent dirt and debris from entering during shipping. The 23XL is shipped with a full oper- ating oil charge.
IDENTIFY MACHINE Ð The machine model number, se- rial number, and heat exchanger sizes are stamped on ma- chine information plate (Fig. 1, 2, and 3). Check this infor- mation against shipping papers and job data.
