General safety guidelines Important: Read before proceeding. This equipment is a relatively complicated apparatus. During rigging, installation, operation, maintenance, or service, individuals may be exposed to certain components or conditions including, but not limited to: heavy objects, refrigerants, materials under pressure, rotating components, and both high and low voltage.
WARNING External wiring, unless specified as an optional connection in the manufacturer’s product line, is not to be connected inside the control cabinet. Devices such as relays, switches, transducers and controls and any external wiring must not be installed inside the micro panel. All wiring must be in accordance with Johnson Controls’...

Shipping and reassembly This instruction explains the procedure to be used for reassembling the Model YK Chiller shipped disassembled (Shipping Form 3, 7, 9, and 10). Note: Chillers must be field reassembled under the supervision of a Johnson Controls representative. For instructions on installing the unit, refer to the Unit Installation Instructions (Form 160.76-N1).
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.
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.
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.

Shipment Form 2/3/7/9 All openings on the compressor, shells including evaporator and condenser, and oil reservoir are closed and charged with nitrogen (2 psig to 3 psig). WARNING To remove the closures, sealing caps, or sealing plug under pressure is extremely dangerous, and may cause severe injury or death to the operator or people on-site.
Form 3 and Form 7 shipment Assemble vibration isolators to unit. Refer to the Unit Installation Instructions (Form 160.76-N1). Level shells in both directions. Check the longitudinal alignment of the shell by placing a level on the top of the shell, next to the discharge connection. Check the transverse alignment by placing a level on the tops of both end sheets.
Figure 4: Rigging – compressor/motor assembly Note: Rig the driveline into place on the chiller, supporting the compressor with two lifting lugs and the motor with either, one, two, or four legs depending on motor design. Form 9 and Form 10 reassembly Assemble vibration isolators to unit.

Note: Relief valves must be plugged or capped. Refer to Operations and Maintenance (Form 160.76-O1). Form 9 - Remove nitrogen and charge unit with refrigerant. Refer to Operations and Maintenance (Form 160.76-O1). 10. All Units: Complete installation and finally level the unit. Refer to Installation Manual (Form 160.76-N1).
