4.2.1 Cooling Adapter Removal and Installation
Cooling Adapter Removal
1. Isolate the compressor and recover the refrigerant according to industry standards. Refer to Section 3.1
Refrigerant Containment on page 41.
2. Hold the Adapter Body with a 15/16" line wrench while loosening the Connection Nut with another
15/16" line wrench.
3. Remove the line away from the Adapter Body.
4. Remove the Adapter Body with a 15/16" line wrench.
5. Remove O-ring from the compressor housing if it does not come out with the Adapter Body.
Cooling Adapter Installation
1. Verify the threads in the compressor housing are clean and free of debris (do not use compressed gas
to clean the threads as this may blow the debris into the compressor).
2. Clean and lubricate the O-ring. Install onto the cooling adapter body.
3. Insert the cooling adapter body into the compressor and finger tighten.
4. Torque the cooling adapter body to the compressor housing to 25 Nm (18 ft.lb.).
5. Install the screen inside the cooling adapter.
6. Install the braze sleeve and nut minus the O-ring. Tighten the nut finger tight against the Cooling
Adapter. This will allow for the measurement and fitting of the liquid line. Once the measuring and
fitting of the liquid line has been completed, unscrew the nut from the cooling adapter body and
complete the brazing of the liquid line to the braze sleeve.
7. Once the Cooling Adapter assembly has cooled, install the O-ring into the Cooling Adapter and the
finger tighten the nut. Torque the nut to 11 Nm (8 ft.lb.).
8. Leak test and evacuate compressor in accordance with standard industry practices.
NOTE
A magnet may need to be placed on the motor cooling solenoids if evacuation cannot be performed directly to the liquid line.
9. Return the compressor to normal operation.
