The shipment can include miscellaneous packaging of the control center, oil eductor filter, tubing,
water temperature controls, wiring, oil, isolators, or the solid state starter or variable speed drive
(VSD) options. The refrigerant charge is shipped in appropriate cylinders. For P and Q compressors,
the control panel is removed for shipment. For H9 and K compressors, the control panel is shipped
on a folded bracket. Refer to the Installation guide (Form 160.75-N1.EN.CE) for more details.
Form 7 – Split shells
The unit is shipped as three major assemblies. The unit is first factory assembled, refrigerant piped,
wired and leak tested; then dismantled for shipment. Close-coupled compressor and open motor
assembly is removed from shells and skidded.
The evaporator and condenser shells are separated at tube sheets and are not skidded. The
refrigerant lines between the shells are flanged and capped. The tube sheets are also bolted, and
do not require welding.
All wiring integral with the compressor is left on the compressor. All wiring harnesses on shells are
removed.
All openings on compressor and shells are closed and charged with dry nitrogen to a pressure of
0.5 barg.
The shipment can include miscellaneous packaging of control center, oil eductor filter, tubing,
water temperature controls, wiring, oil, isolators, or the solid state starter or variable speed drive
options. The refrigerant charge is shipped in appropriate cylinders. For P and Q compressors, the
control panel is removed for shipment. For H9 and K compressors, the control panel is shipped on a
folded bracket. Refer to the Installation guide (Form 160.75-N1.EN.CE) for more details.
Note: When more than one chiller is involved, the major parts of each unit are marked to
prevent mixing of assemblies. Piping and wiring drawings are provided by Johnson Controls.
Inspection, damage, and shortage
Check the unit shipment on arrival to confirm that all major pieces, boxes, and crates are received.
Each unit must be checked on the trailer or rail car when received, before unloading, for any visible
signs of damage. Report any damage or signs of possible damage to the transportation company
immediately for their inspection.
