INTRODUCTION
General
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, field wiring, field piping and insulation
are the responsibility of the contractor and/or customer. See
Fig. 1 for model number information.

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 The machine model number,
serial number, and heat exchanger sizes are stamped on
machine identification nameplate (Fig. 1). Check this infor-
mation against shipping papers and job data.
PROVIDE MACHINE PROTECTION 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 filled.
Rigging the Machine The 17/19EX machine can
be rigged as an entire assembly. It also has flanged 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 See rigging instructions on
label attached to machine. Also refer to the rigging infor-
mation found in Fig. 4-9 and Tables 1-12. Lift machine only
from the 4 points indicated in rigging guide.Each lifting cable
or chain must be capable of supporting the entire weight of
the machine.
Lifting machine from points other than those specified
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.
