Chiller Description
Chiller Scope
This manual provides relevant data to properly
operate, maintain, and troubleshoot the Trane
Manhattan™ Gen IIAir-Cooled Modular Chiller.
Operator and maintenance personnel must be a
qualified refrigeration technician and have a working
knowledge of high voltage systems, low voltage
control circuits, and components and functions.
Chiller Capacities
The Manhattan™ Gen II Chiller model is available in 10-
, 12.5- 15-, 20-, 25-, 30-, 40-, 50-, 60-, and 80-ton capacity
modules. Up to 10 modules may connect together in a
standard primary/secondary control system. The
system consists of a primary chiller module that
contains the primary microprocessor controller, the
power distribution panel, one or more secondary
modules, an optional tank and pump module with a
glycol feed system, and expansion tank or sealed
buffer tank, an optional free-cooling module (air cooled
modules). It is important to connect modules in the
correct sequence as detailed in Handling of the
Modules section of the Installation Mechanical chapter.
The Manhattan™ Gen II Chiller uses independent
refrigeration circuits in each module using scroll
compressors. Models are available with either brazed-
plate or shell-and-tube evaporators. The brazed-plate
evaporator is typically made of SAE Grade 316
Copeland Compressor
8
stainless steel and 99.9% copper brazing materials.
Standard interconnecting headers are composed of
carbon steel.
Water quality must be monitored and maintained by a
water treatment professional familiar with the
materials of construction and operation of the
equipment. The chiller modules arrive fully charged
with refrigerant. As required under Federal regulations,
installation, initial start-up, and technical servicing
should only be performed by fully qualified personnel.

Component Description
Every chiller is comprised of four basic components:
compressor, condenser, expansion valve, and
evaporator. Each Manhattan™ Gen II Chiller module
contains one or more of these primary refrigeration
components.
For chillers larger than ten tons, the Copeland scroll compressor with
CoreSense technology is a state-of-the-art compressor with relay and
overload monitoring capabilities designed to accommodate liquids
(both oil and refrigerant) without causing compressor damage. The
Copeland compressor uses CoreSense technology as a sensor to
unlock advanced capabilities such as protection, diagnostics,
communication, and verification. Technicians can make faster, more
accurate decisions resulting in improved compressor performance and
reliability.
