    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.

  • Page 10: Inspection - Damage - Shortage

    Inspection – damage – shortage The unit shipment must be checked on arrival to see 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.

  • Page 11: Long-Term Storage

    Long-term storage About this task: In order to protect the waterbox of pressure vessels from rusting, the tube side (water side) has been purged and charged with nitrogen to a positive pressure of 5 psig to 7 psig. Do not break the seal or remove closures until ready for setup. Use the following procedure to relieve pressure.
