Johnson Controls YORK User Manual

Shipment
The chiller may be ordered and shipped in any of the following forms:
• Form 2
• Form 3
• Form 7
Form 2 - Factory assembled unit, complete with motors
Note that the refrigerant and oil charges are shipped separately.
• H9, K1, and K2 liquid chilling units.
• The motor/compressor assemblies mounted, with all necessary interconnecting piping
assembled. OptiView
™
Control Center is mounted on the unit. Complete unit factory leak tested,
evacuated and charged with holding charge of nitrogen.
• Miscellaneous material – vibration isolation pads (or optional spring isolators and brackets) will
ship loss.
Note: Units shipped dismantled must be reassembled by, or under the supervision of, a
Johnson Controls representative.
Form 3 - Drivelines separate from shells
• H9, K1, and K2 liquid chilling units.
The chiller is shipped as three major assemblies. The unit first is factory assembled, and the
refrigerant piped, wired, and leak tested. It is then dismantled for shipment. The compressor and
motor assemblies are removed from the shells and skidded. The evaporator and condenser are not
skidded.
All wiring integral with compressors are left on them, and all conduit is left on the shell. All
openings on compressors, oil separator, and shells are closed and charged with dry nitrogen (2 psig
to 3 psig) (14 kPa to 21 kPa).
The control center, oil pump panel, and associated wiring remain mounted on the evaporator
shell. Miscellaneous packaging of tubing, wiring, oil, isolators, and similar components, and the
refrigerant charge are shipped separately.
Form 7 - Split shells
• H9, K1, and K2 optional shipment.
• K3, K4, and K7 standard shipment.
The chiller is shipped as four major assemblies. The unit first is factory assembled, and the
refrigerant piped, wired, and leak tested. It is then dismantled for shipment. The compressor and
motor assemblies are removed from the shells and skidded.
The evaporator and condenser shells are separated at tube sheets and are not skidded. The
refrigerant lines between shells are flanged and capped.
Note: The tube sheets are also bolted, requiring no welding. See Figure 1.
All wiring integral with the compressors are left on them. All wiring harnesses on the shells are
removed. All openings on the compressors and shells are closed and charged with dry nitrogen (2
psig to 3 psig) (14 kPa to 21 kPa).
