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 entering
machine components during shipping. A full operating
inhibitor charge is placed in the unit before shipment from
the factory.

IDENTIFY MACHINE

The machine model number, serial number, and heat exchanger
sizes are shown 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 re-
quirements 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 regulations).
General recommendations are included in the Carrier field wir-
ing drawings. Consult drawing for termination lug sizes.

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 any panels. Knock-
outs are provided on the enclosure. The VFD entry plate is de-
signed to be removed before any holes are made to prevent par-
ticulate from entering the cabinet.
Recommended Control and Signal Wire Sizes
The recommended 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).
Required Airflow Clearances
Be sure there is adequate clearance for air circulation around the
enclosure. A 6-in. (152.4 mm) minimum clearance is required
wherever vents are located in an 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 in-
put power rating. Be sure the input power to the chiller corre-
sponds to the chiller's nameplate voltage, current, and frequency
and to the design data sheet provided by the equipment salesman.
Verify all electrical inputs against design data sheets. The VFD
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 moisture as identified in the long term storage require-
ments. Inspect under shipping tarps, bags, or crates to be sure
that water has not collected during transit. Keep protective
shipping covers in place until machine is ready for installation.
