16. Remove electric compressor (1) from the vehicle.
WARNING:
To prevent electric shock hazards, be sure to wear
protective gear.
17. Remove bolts (A), and then remove compressor bracket (1).
WARNING:
To prevent electric shock hazards, be sure to wear
protective gear.
INSTALLATION
Note the following items, and then install in the reverse order of removal.
WARNING:
To prevent electric shock hazards, be sure to wear protective gear.
CAUTION:
• Be sure to reinstall high voltage harness clips in their original positions. If a clip is damaged, replace
it with a new clip before installing.
• Before installing the new compressor, adjust the compressor oil level. Refer to
Adjusting Procedure for Compressor Replacement"
• To prevent degradation in insulation performance, use special electric compressor oil as the com-
pressor oil.
• In order to prevent conventional PAG oil from becoming mixed in, never reuse recovered compres-
sor oil and instead always use new oil. The use of oil including the conventional PAG oil may
degrade the performance of insulation.
• To prevent performance degradation, never use a fluorescent agent in order to detect refrigerant
leakage. Also be careful that a fluorescent agent never enter the oil.
• To prevent leakage of refrigerant, replace the O-ring with a new one. Apply a coat of compressor oil
to the O-ring prior to installation.
• Perform a check for refrigerant leakage when charging with refrigerant. Refer to
.
• Set the vehicle to READY and operate the air-conditioner for at least 1 minute with the vehicle parked
to perform a break-in.

ELECTRIC COMPRESSOR
• If the compressor stay was replaced, first check that there is no
dust or dirt on the surface of the compressor stay, then apply the
new high voltage warning label at position (1), with the direction
indicated by the arrow facing up.
• Follow the procedure below and connect the high voltage harness connector.
• After all parts are installed, be sure to check the equipotential. Refer to
Inspection
INFOID:0000000010122171
EQUIPOTENTIAL TEST
After installing the electric compressor, measure the resistance below.
• Between electric compressor (aluminum part) and body (ground bolt).
• Between electric compressor (aluminum part) and DC/DC-J/B (aluminum part).
WARNING:
To prevent electric shock hazards, be sure to wear protective gear.
If the result deviates from the standard value, check for paint, oil, dirt, or other substance adhering to the bolts
or conductive mounting parts. If such substances are found, clean the surrounding area and remove foreign
substances.

DANGER:
Since hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of
electric shock, electric leakage, or similar accidents if the high voltage component and vehicle are
handled incorrectly. Be sure to follow the correct work procedures when performing inspection and
maintenance.
