SECTION 1 - OVERVIEW
GENERAL
This manual provides instructions for rigging and in-
stalling a YMC2Liquid Chilling Unit.
Chillers can be shipped as a single factory assembled,
piped, wired package, requiring a minimum of field la-
bor to make chilled water connections, condenser wa-
ter connections, refrigerant atmospheric relief connec-
tions, and electrical power connections. (Refrigerant
charges shipped separately unless optional condenser
isolation valves are ordered.)
They can also be shipped dismantled when required by
rigging conditions, but it is generally more economical
to enlarge access openings to accommodate the factory
assembled unit. Chillers that are shipped dismantled
MUST be field-assembled under the supervision of a
Johnson Controls representative, but otherwise instal-
lation will be as described in this manual.
COMPONENT COMBINATIONS
Figure 1 identifies the major components of the YMC2
Chiller. The chiller is customized based on the selected
combination of Motor, Compressor, Evaporator, and
Condenser. Section 5 - Dimensions, Nozzle Arrange-
ments And Weights lists all of the allowable YMC2
Chiller combinations.

3. When units are shipped dismantled, notify the
nearest Johnson Controls ofce in ample time for
a Johnson Controls representative to supervise
rigging the unit to its operating position and the
assembly of components.
4. Do not make nal power supply connections to
the compressor motor drive or control center.
5. Do not charge the unit with refrigerant.
6. Do not attempt to start the system.
7. Do not run hot water (>110°F / 43°C max) or
steam through the evaporator or condenser at any
time.
CHILLER DATA PLATE
A unit data plate is mounted on the control center as-
sembly of each unit, giving unit model number; design
working pressure; water passes; refrigerant charge; se-
rial numbers; and motor power characteristics and con-
nection diagrams.
Additional information may be found on the compres-
sor and motor data plates. This information should be
included when contacting the factory on any problem.
YMC2SHIPMENT FORMS
The chiller may be ordered and shipped in any of the
following forms:
• Form 1 (shipped complete with refrigerant charge)
• Form 2 (shipped complete with refrigerant charge
shipped separately)
• Form 3 (shipped in three assemblies)
• Form 7 (shipped in four assemblies)
• Form 9 (shipped in two assemblies with refriger-
ant charge shipped separately)
• Form 10 (shipped in two assemblies with refriger-
ant charge)
• Form 11 (shipped as split shells with refrigerant
charge)
Units that are shipped dismantled MUST
be reassembled by, or under the supervi-
sion of a Johnson Controls representative.
Refer to Section 4 - Reassembly for de-
tailed reassembly instructions.
INSPECTION – DAMAGE – SHORTAGE
The unit shipment should be checked on arrival to see
that all major pieces, boxes and crates are received.
Each unit should be checked on the trailer or rail car
when received, before unloading, for any visible signs
of damage. Any damage or signs of possible damage
must be reported to the transportation company imme-
diately for their inspection.
JOHNSON CONTROLS WILL NOT BE RESPON-
SIBLE FOR ANY DAMAGE IN SHIPMENT OR AT
JOB SITE OR LOSS OF PARTS. (Refer to Shipping
Damage Claims Form (Form 50.15-NM).
When received at the job site all containers should be
opened and contents checked against the packing list.
Any material shortage should be reported to Johnson
Controls immediately. (Refer to Shipping Damage
Claims Form (Form 50.15-NM).
YMC2Chillers are not intended to be stored outdoors,
exposed to rain and moisture. The shipping wrap is for
shipping, not for extended outdoor storage. The chiller
should be tarped during any delays to get indoors and
moisture desiccant, available for purchase for inside
electrical panels should be used for damp areas.
If the chiller was not shipped complete (as shown in
Form 1 or 2) use the Section 4 - Reassembly in con-
junction with this installation manual.
The services of a Johnson Controls representative will
be furnished to check the installation, supervise the
initial start-up and operation of all chillers installed
within the Continental United States.
The Johnson Controls Warranty may be
voided if the following restrictions are not
adhered to.
1. No valves or connections should be opened under
any circumstances because such action will result
in loss of the factory refrigerant (Form 1) or nitro-
gen charge (Form 2).
2. Do not dismantle or open the chiller for any rea-
son except under the supervision of a Johnson
Controls representative.

Improper use of rigging equipment can
result in serious injury. Do not operate
without proper training and authorization.
It is the responsibility of the installer to
have a qualied and certied crane opera-
tor and rigger for lifting components and
relocating to the new site.
To perform a safe and effective rigging practice the
installer is responsible for inspection and operation
of the lifting equipment, special site considerations,
proper rigging and lifting practices, and any safety
considerations.
Particular items the installer must be aware of are:
• Rope with no visible wear, twisted, kinked, or
damaged chains.
• Deformed, cracked, or stretched hooks or safety
latch on the hook is not damaged.
• Correct drum spooling as the hook is raised.
• Do not operate a damaged or malfunctioning
hoist.
• Do not wrap the hoisting rope or chain around the
load.
• Do not lift loads over people.
