FORM 160.69-N2
ISSUE DATE: 7/31/2015
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 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 plates. This information should be included when
contacting the factory on any problem relating to the
motor.
RIGGING
The complete standard chiller is shipped without skids.
(When optional skids are used it may be necessary to
remove the skids so riggers skates can be used under
the unit end sheets to reduce overall height.)
Each unit has four (4) lifting holes (two in each end)
in the end sheets which should be used to lift the unit.
Care should be taken at all times during rigging and
handling of the chiller to avoid damage to the unit and
its external connections. Lift only using holes shown
in Figure 1 on page 10.
Do not lift the unit with slings around
motor/compressor assemblies or by
means of eyebolts in the tapped holes of
the compressor motor assemblies. Do not
turn a unit on its side for rigging. Do not
rig vertically.
The rigging and operating weights and overall dimen-
sions are given on pages 6 thru 8 as a guide in deter-
mining the clearances required for rigging. Add 6" (15
cm) to overall height for optional skidded unit.
The lengthwise rigging bar should be longer than the
chiller tube length, and must have counter or clevis ad-
justments to allow for center of gravity adjustments.
Chain spreaders should be used to avoid contact with
drive motors or other chiller parts.

LOCATION
YORK Chillers are furnished with vibration isola-
tor mounts for basement or ground level installations.
Units may be located on upper floor levels providing
the floor is capable of supporting the total unit operat-
ing weight and optional spring isolators are used.
Sufficient clearance to facilitate normal
service and maintenance work must be
provided all around and above the unit
and particularly space provided at either
end to permit cleaning or replacement
of evaporator and condenser tubes – see
CLEARANCE. A doorway or other suf-
ficiently large opening properly located
may be used. The chiller should be located
in an indoor location where tempera-
tures range from 40°F to 110°F (4.4°C
to 43.3°C).
MOTORS
The YK open motor is air cooled. Check state, local
and other codes for ventilation requirements.
FOUNDATION
A level floor, mounting pad or foundation must be pro-
vided by others, capable of supporting the operating
weight of the unit.
CLEARANCE
Clearances should be adhered to as follows:
• Rear and above unit – 2 ft (61 cm).
• Front of unit – 3 ft (91 cm).
• Tube Removal – 22 ft. (6.7 m) (either end)
18 ft. (5.5 m) (either end)
