INSTALLATION
INTRODUCTION
General Ð The 17/19EX machine is factory assembled, wired, and leak tested. Installation consists primarily of es- tablishing water and electrical services to the machine. The rigging, installation, ®eld wiring, ®eld piping and insulation are the responsibility of the contractor and/or customer. See Fig. 1 for model number information.

·leak detector (halide or electronic)
·absolute pressure manometer or
·portable vacuum pumps
INSTALLATION
Receiving the Machine
INSPECT SHIPMENT
Do not open any valves or loosen any connections. The standard 17/19EX machine may be shipped with a ni- trogen holding charge or with the refrigerant charge iso- lated within the utility vessel.
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. Manufacturer 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 en- tering the machine's components during shipping. A full operating oil charge is placed in the oil sump of the com- pressor before shipment.
IDENTIFY MACHINE Ð The machine model number, serial number, and heat exchanger sizes are stamped on machine identi®cation nameplate (Fig. 1). Check this infor- mation against shipping papers and job data.
PROVIDE MACHINE PROTECTION Ð Protect machine and starter from construction dirt and moisture. Keep pro- tective shipping covers in place until machine is ready for installation.
If machine is exposed to freezing temperatures after water circuits have been installed, open waterbox drains and re- move all water from cooler and condenser. Leave drains open until system is ®lled.
Rigging the Machine Ð The 17/19EX machine can be rigged as an entire assembly. It also has ¯anged connec- tions that allow the compressor, utility vessel, cooler, and condenser sections to be separated for ease of installation. Figures 2 and 3 show 17/19EX components.
RIG MACHINE ASSEMBLY Ð See rigging instructions on label attached to machine. Also refer to the rigging infor- mation found in Fig.
Lifting machine from points other than those speci®ed may result in serious damage to the unit and personal injury. Rigging equipment and procedures must be ad- equate for machine weight. See Table 1 for machine weights.
NOTE: These weights are broken down into compo- nent sections for use when installing the unit in sections. For the complete machine weight, add all com- ponent sections and refrigerant charge together. Total machine weight is also stenciled on the cooler and con- denser sections.
