piping prints and details

field wiring drawings

starter manufacturer’s installation details

Carrier certified print

INSTALLATION

Receiving the Machine

INSPECT SHIPMENT

Do not open any valves or loosen any connections. The 23XRV machine may be shipped with a full refrigerant charge. Some machines may be shipped with a nitrogen holding charge as an option.

1.Inspect for shipping damage while machine is still on ship- ping conveyance. If machine appears to be damaged or has been torn loose from its anchorage, have it examined by transportation inspectors before removal. Forward claim papers directly to transportation company. Manufac- turer is not responsible for any damage 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 beginning installation. All openings are closed with covers or plugs to prevent dirt and debris from enter- ing machine components during shipping. A full operating oil charge is placed in the oil sump before shipment.

IDENTIFY MACHINE (Fig. 1-4) — Refer to machine name- plate in Fig. 1. The machine model number, serial number, and heat exchanger sizes are stamped on the Refrigeration Machine nameplate located on the side of the VFD (variable frequency drive) enclosure. Check this information against shipping papers and job data.
