This equipment is a relatively complicated apparatus.
During rigging, installation, operation, maintenance,
or service, individuals may be exposed to certain com-
ponents or conditions including, but not limited to:
heavy objects, refrigerants, materials under pressure,
rotating components, and both high and low voltage.
Each of these items has the potential, if misused or
handled improperly, to cause bodily injury or death. It
is the obligation and responsibility of rigging, instal-
lation, and operating/service personnel to identify and
recognize these inherent hazards, protect themselves,
and proceed safely in completing their tasks. Failure
to comply with any of these requirements could result
in serious damage to the equipment and the property in

GENERAL SAFETY GUIDELINES
which it is situated, as well as severe personal injury or
death to themselves and people at the site.
This document is intended for use by owner-authorized
rigging, installation, and operating/service personnel. It
is expected that these individuals possess independent
training that will enable them to perform their assigned
tasks properly and safely. It is essential that, prior to
performing any task on this equipment, this individual
shall have read and understood the on-product labels,

dividual shall also be familiar with and comply with
all applicable industry and governmental standards and
regulations pertaining to the task in question.
SAFETY SYMBOLS
The following symbols are used in this document to alert the reader to specific situations:
Indicates a possible hazardous situation
which will result in death or serious injury
if proper care is not taken.
Indicates a potentially hazardous situa-
tion which will result in possible injuries
or damage to equipment if proper care is
not taken.
Identies a hazard which could lead to
damage to the machine, damage to other
equipment and/or environmental pollu-
tion if proper care is not taken or instruc-
tions and are not followed.
Highlights additional information useful
to the technician in completing the work
being performed properly.
External wiring, unless specied as an optional connection in the manufacturer’s product line, is not
to be connected inside the control cabinet. Devices such as relays, switches, transducers and controls
and any external wiring must not be installed inside the micro panel. All wiring must be in accor-
dance with Johnson Controls’ published specications and must be performed only by a qualied
electrician. Johnson Controls will NOT be responsible for damage/problems resulting from improper
connections to the controls or application of improper control signals. Failure to follow this warn-
ing will void the manufacturer’s warranty and cause serious damage to property or personal injury.

The chiller is controlled by a modern state of the art
Microcomputer control center that monitors its opera-
tion. The control center is programmed by the opera-
tor to suit job specifications. Automatic timed start-ups
and shutdowns are also programmable to suit night-
time, weekends, and holidays. The operating status,
temperatures, pressures, and other information perti-
nent to operation of the chiller are automatically dis-
played and read on a graphic display. Other displays
can be observed by pressing the keys as labeled on the
control center. The chiller with the OptiView control
center is applied with a Variable Speed Drive.
In operation, a liquid (water or brine to be chilled)
flows through the cooler, where boiling refrigerant ab-
sorbs heat from the liquid. The chilled liquid is then
piped to fan coil units or other air conditioning terminal
units, where it flows through finned coils, absorbing
heat from the air. The warmed liquid is then returned
to the chiller to complete the chilled liquid circuit. (See
Figure 2 on Page 10)
SECTION 1 - DESCRIPTION OF SYSTEM AND
FUNDAMENTALS OF OPERATION
SYSTEM OPERATION DESCRIPTION
This manual covers the operation of the YMC2Chiller
with M1B motor, but having two separate means of
capacity control and motor cooling based on the com-
pressor gas path revision level A or B as identified in
the compressor model number. See the compressor
nomenclature description at the front of this manual.
Items in this manual will be specified pertinent to only
one specific compressor gas path revision level where
applicable and defined separately for either style in
other cases. Watch for notes regarding the separate va-
rieties when reviewing the information.
The YORK Model YMC2Chiller is commonly applied
to large air conditioning systems, but may be used on
other applications. The chiller consists of hermetic
motor mounted to a compressor, condenser, evaporator
and variable flow control.
