Form 7 - Split Shells; Form 9 - Unit Separate From Variable Speed Drive; Form 10 - Unit Separate From Variable Speed Drive - York YK Series Installation Manual

The shipment may include miscellaneous packaging of the control center, oil eductor filter,
tubing, water temperature controls, wiring, oil, isolators, 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 Unit Installation Instructions (Form 160.76-N1) for more details.
Form 7 – Split shells
Shipped as three major assemblies. The unit is first factory assembled, refrigerant piped, wired
and leak tested; then dismantled for shipment. Close-coupled compressor/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,
requiring no welding.
All wiring integral with the compressor is left on. All wiring harnesses on shells are removed.
All openings on compressor and shells are closed and charged with dry nitrogen (2 psig or 3 psig).
