Be sure to read and follow the “General Safety Information
and Caution” before doing any work related with the high voltage
system. Failure to follow the safety instructions may result in serious
electrical injuries.
•
Be sure to shut off the high voltage before doing any work
related with the high voltage system(Refer to "High Voltage Shut-off
Procedure"). Failure to follow the safety instructions may result in
serious electrical injuries.
•
Put on gloves to protect your hands.
•
When prying with a flat-tip screwdriver, wrap it with
protective tape, and apply protective tape around the related parts, to
prevent damage.
•
Use a plastic panel removal tool to remove interior trim pieces to protect from marring the surface.
•
Take care not to bend or scratch the trim and panels.
1.
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.
Disconnect the negative (-) battery terminal.
3.
Shut off the high voltage circuit. (Refer to EV Battery System - "High Voltage Shut-off Procedure")
4.
Remove the cowl top cover.
(Refer to Body - "Cowl Top Cover")
5.
Remove the pipe (A) after loosening the mounting bolts.
6.
Remove the expansion valve (A) after loosening the mounting bolts from the evaporator core.
Inspection
1.
Connect the battery voltage and check for the blower motor rotation.
2.
If the blower motor voltage does not operate well, substitute with a verified blower motor and check for p ...
