All wiring integral with compressor is left on
it, and all conduit is left on shell. All openings
on compressor, oil separator, and shell are
closed and charged with dry nitrogen (2 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.
(See Form 160.75-N3)
Form 7 – Split Shells – Shipped as three major
assemblies. Unit first factory assembled,
refrigerant piped, wired and leak tested; then
dismantled for shipment. Compressor/motor
assembly removed from shells and skidded.
Evaporator and condenser shells are separated
at tube sheets and are not skidded. Refrigerant
lines between shells are flanged and capped,
requiring no welding.
All wiring integral with compressor is left on
it. All wiring harnesses on shells are removed.
All openings on compressor and shells are
closed and charged with dry nitrogen (2 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.

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 immediately
for their inspection.
JOHNSON CONTROLS WILL NOT bE RESPONSIbLE
FOR ANY DAMAGE IN SHIPMENT OR AT JOb SITE
OR LOSS OF PARTS. (Refer to Shipping Damage

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

chillEr data PlatE
A unit data plate is mounted on the control center
assembly of each unit, giving unit model number; design
working pressure; water passes; refrigerant charge;
serial numbers; and motor power characteristics and
connection diagrams.
Additional information may be found on the motor
data plate. This information should be included when
contacting the factory on any problem relating to the
motor.
rigging (see fig. 18)
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 FIG. 18.
Do not lift the unit with slings around
motor/compressor assembly or by
means of eyebolts in the tapped holes
of the compressor motor assembly. Do
not turn a unit on its side for rigging.
Do not rig vertically.
