INTRODUCTION
General —
The 19XR machine is factory assembled,
wired, and leak tested. Installation (not by Carrier) consists pri-
marily of establishing water and electrical services to the ma-
chine. The rigging, installation, field wiring, field piping, and
insulation of waterbox covers are the responsibility of the con-
tractor and/or customer. Carrier has no installation responsibili-
ties for the equipment.
Job Data
Necessary information consists of:
• job contract or specifications
• machine location prints
• rigging information
• piping prints and details
• field wiring drawings
• starter manufacturer’s installation details
• Carrier certified print
INSTALLATION
Step 1 — Receive the Machine
INSPECT SHIPMENT
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
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
control panels. Knockouts are provided on the enclosure.
CAUTION
Do not open any valves or loosen any connections. The
19XR machine may be shipped with a nitrogen holding
charge in both modules. Damage to machine may result.
