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
packages until beginning installation. All openings are
closed with covers or plugs to prevent dirt and debris
from entering machine components during shipping. A
full operating oil charge is placed in the oil sump before
shipment.
IDENTIFY MACHINE — The machine model number, seri-
al number, and heat exchanger sizes are stamped on machine
identification nameplate (Fig. 1-3). Check this information
against shipping papers and job data.
INSTALLATION REQUIREMENTS — Prior to starting the
chiller’s electrical installation, certain requirements should be
checked. Input power wire sizes, branch circuit protection, and
control wiring are all areas that need to be evaluated.
Determine Wire Size Requirements
— Wire size should be
determined based on the size of the conduit openings, and
applicable local, national, and international codes (e.g., NEC
[National Electric Code]/CEC [California Energy Commis-
sion] regulations). General recommendations are included in
the Carrier field wiring drawings.
Conduit Entry Size
— It is important to determine the size of
the conduit openings in the enclosure power entry plate so that
the wire planned for a specific entry point will fit through the
opening. Do NOT punch holes or drill into the top surface of
starter or drive if knockouts are provided on the side of the en-
closure and not the top of the enclosure.
Recommended Control and Signal Wire Sizes
— The rec-
ommended minimum size wire to connect I/O signals to the
control terminal blocks is 18 AWG (American Wire Gage).
Recommended terminal tightening torque is 7 to 9 in.-lb
(0.79 to 1.02 N-m).
Recommended Airflow Clearances
— Be sure there is ade-
quate clearance for air circulation around the enclosure.
A 6-in. (152.4 mm) minimum clearance is required wherever
vents are located in the starter or drive enclosure.
Service Clearances
— Verify that there are adequate service
clearances as identified in Fig. 4.
Verify Adequate Power Supply
— It is important to verify
that the building power will meet the input power requirements
of the Machine Electrical Data nameplate input power rating.
Be sure the input power to the chiller corresponds to the
chiller’s nameplate voltage, current, and frequency.
PROVIDE MACHINE PROTECTION — Store machine
and VFD (variable frequency drive) indoors, protected from
construction dirt and moisture. Inspect under shipping tarps,
bags, or crates to be sure water has not collected during transit.
Keep protective shipping covers in place until machine is ready
for installation.
It is important to properly plan before installing a 19XR or
19XRV unit to ensure that the environment and operating con-
ditions are satisfactory and the machine is protected. The in-
stallation must comply with all requirements in the certified
prints.
Operating Environment
— Chiller should be installed in an
indoor environment where the ambient temperature is between
40 to 104 F (4 to 40 C) with a relative humidity (non-condens-
ing) of 95% or less. To ensure that electrical components oper-
ate properly, do not locate the chiller in an area exposed to dust,
dirt, corrosive fumes, or excessive heat and humidity.
Step 2 — Rig the Machine — The 19XR,XRV ma-
chine can be rigged as an entire assembly. It also has flanged
connections that allow the compressor, cooler, and condenser
sections to be separated and rigged individually.
RIG MACHINE ASSEMBLY — See rigging instructions on
label attached to machine. Refer to rigging guide (Fig. 5 and 6),
physical data in Fig. 4, and Tables 1-8B. Lift machine only from
the points indicated in rigging guide. Each lifting cable or
chain must be capable of supporting the entire weight of the
machine.
Contractors are not authorized to disassemble any part of
the chiller without Carrier's supervision. Any request otherwise
must be in writing from the Carrier Service Manager.
NOTE: Carrier suggests that a structural engineer be consulted
if transmission of vibrations from mechanical equipment is of
concern.

CAUTION
Freezing water can damage equipment. If machine can be
or possibly has been exposed to freezing temperatures after
water circuits have been installed, open waterbox drains
and remove all water from cooler and condenser. Leave
drains open until system is filled.
WARNING
Lifting chiller module from points other than those speci-
fied may result in serious damage to the machine or per-
sonal injury. Rigging equipment and procedures must be
adequate for maximum chiller module weight. See Fig. 5
and 6 for maximum chiller module weights.
