N No otte e:: This manual applies to model CDHF, CDHG,
CVHE, CVHF, and CenTraVac chillers.
IIm mp po orrtta an ntt:: Remove the nitrogen charge from the
chiller vessel before starting any
disassembly procedures.
N No otte e:: New units ship with a 5 psig (34.5 kPag) dry
nitrogen holding charge at nominal 72°F (22°C).
IIm mp po orrtta an ntt:: New units that have been factory run-tested

Introduction
The disassembly and reassembly procedures described
in this manual should be performed only on chillers
that have been ordered with this shell option. The
process is to be initiated by experienced service
technicians. Contact your local Trane Service office for
assistance if required.
This section discusses a typical disassembly process.
Proper lifting techniques vary based on mechanical
room layout.
• It is the responsibility of the person(s) performing
the work to be properly trained in the safe practice
of rigging, lifting, securing, and fastening the
components involved.
• It is the responsibility of the person(s) providing
and using the rigging and lifting devices to inspect
these devices to ensure they are free from defect
and are rated to meet or exceed the published
weights.
• Always use rigging and lifting devices in
accordance with the applicable instructions for such
devices.
N No otte e:: Additional gaskets and O-rings are shipped with
the chiller when compressor doweling and/or
separable shells are selected.
