16. Continue the removal of the compressor and lower to the desired location in order to remove
the chains/cables.
17. Using the blanking plates and bolts provided with the new compressor, seal the compressor
and charge to 15 psi with a nontoxic inert gas (e.g., nitrogen) for shipment (this will prevent
moisture and foreign material from entering the compressor).
3.3 Compressor Installation
1. Relieve the inert gas pressure through the motor cooling exit port Schrader valve.
2. Remove the suction, discharge, and economizer (if applicable) blanking plates from the
compressor.
3. Remove the motor cooling inlet adapter cap. Refer to "3.4 Compressor Replacement
Considerations for Motor Cooling Adapter" on page 43.
4. Ensure that all connections have protective covers to prevent foreign object damage during
installation.
5. Attach the spreader bar to the two (2) lifting hooks (eye bolts) on the top of the compressor
and confirm that all lifting points are secured in accordance with relevant safety procedures
and standards.
6. Position an appropriate lifting hoist/crane and connect to the spreader bar.
7. Confirm that the compressor and spreader bar are properly balanced between the lifting
points and the lifting hoist.
8. Slowly lower the compressor until it is positioned within approximately 5 mm (¼”) of the
compressor mounts.
9. Loosely install the rubber mounts and mounting fasteners to the base of the compressor.
10. Slowly release the load from the crane so that compressor weight is supported by the
compressor mounts.
11. Tighten the suction flange fasteners to 75 Nm (55 ft.lb.).
12. Tighten the discharge flange fasteners to 32 Nm (24 ft.lb.).
13. Tighten the economizer flange fasteners (if applicable) to 32 Nm (24 ft.lb.).
14. Torque the compressor mounting base fasteners to 22 Nm (16 ft.lb.).

NOTE
Blanking plates should not be removed from the new compressor until you are ready to place the new compressor in operation.
New compressors are pressurized with nitrogen to 15 psi. Pressure should be relieved through the Schrader valve, located next to
the motor cooling connection, prior to removing the blanking plates. Isolation and recovery of the refrigerant must be performed
by a qualified technician. Always wear proper safety equipment when handling refrigerants.
NOTE
Install new O-rings when attaching flanges to the compressor.
