INTRODUCTION

General — The19XR machine is factory assembled, wired,

and leak tested. Installation (not by Carrier) consists

primarily of establishing water and electrical services to

the machine.The rigging, installation, ﬁeld wiring, ﬁeld pip-

ing, and insulation of waterbox covers are the responsibility

of the contractor and/or customer.Carrier has no installation

responsibilities 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

INSPECT SHIPMENT

Do not open any valves or loosen any connections. The

standard 19XR machine is shipped with a full refrig-

erant charge. Some machines may be shipped with a ni-

trogen holding charge as an option.

1. Inspectfor 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. Toprevent 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 machine components during shipping. A full op-

erating oil charge is placed in the oil sump before

shipment.

IDENTIFY MACHINE — The machine model number,

serial number, and heat exchanger sizes are stamped on

machine identiﬁcation nameplate (Fig. 1 and 2). Check this

information 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 19XR machine 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 MACHINEASSEMBLY — See rigging instructions on

label attached to machine. Also refer to rigging guide

(Fig. 3 and 4), physical data in Fig. 5, and Tables1-8B. Lift

machine only fromthe points indicated in rigging guide. Each

lifting cable or chain must be capable of supporting the en-

tire 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 Fig. 3 and 4 for ma-

chine 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. See

Tables 4-8B for machine component weights.

IMPORTANT: Ensure that rigging cable is over the

guide bolt or cable hook on the motor end cover be-

fore lifting if cooler size is 10 through 67.
