Shipment Form 2/3/7/9; Shipment Form 1/10; Reassembly; Form 7 Shipment - York YK Series Installation Manual

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).
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.
Before trying to remove these, relieve the pressure in compressor, shells, or system that are charged
with nitrogen by opening the valves on them slowly until fully open.
When relieving the pressure from compressor, shells, or system, conduct the nitrogen to outside to
prevent the potential risk of asphyxiation.

Shipment Form 1/10

The unit is shipped with refrigerant charge; it is not necessary to relieve the pressure. Do not try to
open any valves to relieve pressure or open closures, cap, or plugs on the compressor, shells, and
elsewhere on the system.
Reclaim the refrigerant in the system before any service activities are carried out on the
refrigeration system. Fully relieve system pressure and then repair.
The unit is charged with tons of refrigerant; if an uncontrollable leak is found, inform all of the relevant
people to evacuate from the building to prevent risk of asphyxiation.
Never touch the refrigerant that is leaking, especially the liquid refrigerant; this will cause severe
freezing to your hands or body.

Reassembly

The following is a step-by-step procedure to be used to reassemble the chiller. Refer to the Unit
