INSTALLATION
Step 1 — Receive the Machine
INSPECT SHIPMENT
CAUTION
Do not open any valves or loosen any connections. The
19XRV machine may be shipped with a nitrogen holding
charge in both modules. Damage to machine may result.
1. Inspect for shipping damage while machine is still on
shipping conveyance. If machine appears to be damaged
or has been torn loose from its anchorage, have it exam-
ined by transportation inspectors before removal. For-
ward 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 the refrig-
eration machine nameplate located on the right side of the
control panel (Fig. 1-3). Check this information against
shipping papers and job data.

INSTALLATION REQUIREMENTS — Certain
require-
ments should be checked before continuing with the chiller
electrical installation. Input power wire sizes, branch circuit
protection, and control wiring are all areas that need to be eval-
uated.
Determining 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
the VFD (variable frequency drive) enclosure for field wiring.
Knockouts are provided on the side of the VFD enclosure for
field control wiring connections.
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 VFD enclosure.
Service Clearances — Verify that there are adequate service
clearances as identified in Fig. 4.
Match Power Module Input and Supply Power Ratings — It
is important to verify that 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 fre-
quency. The machine electrical data nameplate is located on
the right side of the VFD enclosure.
PROVIDE MACHINE PROTECTION — Store
machine
and VFD indoors, protected from construction dirt and mois-
ture. Inspect under shipping tarps, bags, or crates to be sure wa-
ter has not collected during transit. Keep protective shipping
covers in place until machine is ready for installation.
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.
It is important to properly plan before installing a 19XRV
unit to ensure that the environment and operating conditions
are satisfactory and the machine is protected. The installation
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.
