Recover the refrigerant with a recovery/ recycling/ charging station.
•
Do not use the same A/C recovery / charging station as conventional belt-driven compressors.
•
Since the electric compressor uses high-voltage, POE oil with high resistivity should be used.
•
If PAG oil mixes into the POE oil of the system, dielectric
breakdown may occur due to decreased volumetric resistivity and the A/C
compressor may not work.
2.
Drain the coolant.
(Refer to Traction Motor System - "Coolant")
3.
Disconnect the negative (-) battery terminal.
4.
Remove the reservoir tank.
(Refer to Traction Motor System - "Reservoir")
5.
Separate the refrigerant line (A) after loosening the mounting bolt.
•
Cap the open fittings immediately to keep moisture or dirt out of the system.
6.
Separate the refrigerant line (A) after loosening nut and then remove the chiller coolant hose (B).
•
Cap the open fittings immediately to keep moisture or dirt out of the system.
7.
Remove the chiller (A) after loosening the mounting bolts.
8.
Install in the reverse order of removal.
•
Do not use the same A/C recovery / charging station as conventional belt-driven compressors.
•
Since the electric compressor uses high-voltage, POE oil with high resistivity should be used.

Inspection
1.
Turn the ignition switch OFF.
2.
Shut off the high voltage.
(Refer to Battery Control System - "High Voltage Shut-off Prcedure")
3.
Remove the high voltage battery system assembly.
(Refer to High Voltage Battery System - Repair procedures - "Removal")
4.
Remove the hi ...
