This equipment is a relatively complicated apparatus.
During installation, operation maintenance or service,
individuals may be exposed to certain components or
conditions including, but not limited to: 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 respon-
sibility of 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

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.

SECTION 1 - INTRODUCTION
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:
• Do not open valves or connections under any cir-
cumstances, as such action will result in loss of
the factory nitrogen charge.
• Do not dismantle or open the chiller for any rea-
son except under the supervision of a Johnson
Controls representative.
• When the 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.
• Do not make nal power supply connections to
the compressor motor or control center.

FIGURE 1 - MODEL YK CHILLER
GENERAL
This manual describes the installation of a YORK YK
Mod "H" Centrifugal Chiller. This unit can be shipped
as a single factory assembled, piped, wired package,
requiring a minimum of field labor to make chilled
water connections, condenser water connections, re-
frigerant atmospheric relief connections, and electri-
cal power connections. Refrigerant and oil charges are
shipped separately unless optional condenser isolation
valves are ordered.
Chillers can also be shipped dismantled when required
by rigging conditions, but generally it is more econom-
ical to enlarge access openings to accommodate the
factory assembled unit. Chillers shipped dismantled
MUST be field assembled under the supervision of a
Johnson Controls representative, but otherwise instal-
lation is as described in this instruction.
FIELD ASSEMBLED UNITS ONLY
Use Unit - Installation Instructions (Form 160.76-N3)
in conjunction with this installation instruction. This in-
struction is furnished with all units that are assembled
in the field.

isolation pads (or optional spring isolators
and brackets). K7 units are shipped with 8
Vibration Isolation Pads.
Form 2 – Factory Assembled Unit, complete with mo-
tor (refrigerant and oil charges shipped sepa-
rately).

tory leak tested, evacuated and charged with
holding charge of nitrogen.
An optional Solid State Starter or Variable
Speed Drive can be factory mounted and
wired.

isolation pads (or optional spring isolators).
K7 units are shipped with 8 Vibration Isola-
tion Pads.
Form 3 – Driveline Separate From Shells – Shipped as
two major assemblies. Unit first factory assem-
bled, refrigerant piped, wired and leak tested;
then dismantled for shipment.
• Compressor/motor assembly removed from
shells and skidded. Evaporator/condenser is
not skidded.
• All wiring integral with compressor is left on
it, and all conduit is left on shell. All open-
ings on compressor, oil separator, and shell
are closed and charged with dry nitrogen
(2 psig to 3 psig) (115/122 kPa).
• Miscellaneous packaging of control center,
tubing, water temperature controls, wiring,
oil, isolators, solid state starter (option), and
so on. The refrigerant charge is shipped sepa-
rately.
Units shipped dismantled MUST be re-
assembled by, or under the supervision of,
a Johnson Controls representative. Refer
to Installation - Unit (Form 160.76-N3)
Form 7 – Split Shells – Shipped as three major assem-
blies. Unit first factory assembled, refriger-
ant piped, wired and leak tested; then dis-
mantled for shipment.
• Compressor/motor assembly removed from
shells and skidded.
• The evaporator and condenser shells are sep-
arated at tube sheets and are not skidded. The
refrigerant lines between shells are flanged
and capped, requiring no welding.
• All wiring integral with compressor is left on
it. All wiring harnesses on the shells are re-
moved. All openings on the compressor and
shells are closed and charged with dry nitro-
gen (2 psig to 3 psig) (115/122 kPa).
• Miscellaneous packaging of control center,
tubing, water temperature controls, wiring,
oil isolators, solid state starter (option), etc.;
refrigerant charge shipped separately.
Units shipped dismantled MUST be re-
assembled by, or under the supervision of,
a Johnson Controls representative. Refer
to Installation - Unit (Form 160.76-N3)
When more than one chiller is involved, the major
parts of each unit are marked to prevent mixing of as-
semblies. (Piping and Wiring Drawings to be furnished

INSPECTION – DAMAGE – SHORTAGE
The unit shipment should be checked on arrival to see
that all major pieces, boxes and crates are received.
Check each unit on the trailer or rail car when received,
before unloading, for any visible signs of damage. Re-
port any damage or signs of possible damage to the
transportation company immediately for their inspec-
tion. Johnson Controls is not be responsible for any
damage in shipment, at job site, or loss of parts. (Refer
to Shipping Damage Claims, Form 50.15-NM.)
When received at the job site, open all containers and
check contents against the packing list. Any material
shortage should be reported to Johnson Controls im-
mediately. (Refer to Shipping Damage Claims, Form
50.15-NM.)
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 motor data
plate. Include this information when contacting the fac-
tory on any problem relating to the motor.
LONG-TERM STORAGE
To protect the waterbox of pressure vessels from rust-
ing, the tube side (water side) is purged and charged
with nitrogen to a positive pressure of 5 psig to 7 psig.
Do not break the seal or remove closures until ready
for set up. Use the following procedure to relieve pres-
sure (see Figure 3 on page 10).
Failure to follow the following procedures
will cause severe personal injury or death
to operators themselves or people on-site.
It is the obligation and responsibility of
operators to identify and recognize the
inherent hazards of material under pres-
sure and to protect themselves.

and shell are closed and charged with dry nitrogen (2 to
3 psig) (115/122 kPa).
Miscellaneous packaging of tubing, water temperature
controls, wiring, isolators, etc. The unit is shipped with
a nitrogen charge. Refrigerant charge shipped in appro-
priate cylinders. See Table 7 on Page 45.
Form 10 – Unit Separate from Variable Speed
