Step 2 — Rig the Machine —
The 23XRV machine
can be rigged as an entire assembly. Large interconnecting pip-
ing has flanged connections that allow the compressor, cooler,
and condenser sections to be separated and rigged individually.
In addition, the VFD can be removed and rigged separately.
RIG MACHINE ASSEMBLY — See rigging instructions on
label attached to machine. Also refer to rigging guide (Fig. 13),
physical data in Fig. 13 and 14, and Tables 3-19.
Lift machine
only from the points indicated in rigging guide.
Each lifting ca-
ble 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.

WARNING
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 adequate for
machine weight. See Fig. 13 for machine weights.
NOTE: These weights are broken down into component
sections for use when installing the unit in sections. For the
complete machine weight, add all component sections and
refrigerant charge together. See Tables 8-19 for machine
component weights.
