[WITH HEAT PUMP SYSTEM]
CONDENSER
Note the following items, and then install in the reverse order of removal.
CAUTION:
• When installing the condenser, securely insert the mating part indicated by the arrow in the diagram.
• 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.
• After installing a new condenser, adjust the compressor oil level. Refer to
ing Procedure for Components Replacement Except Compressor"
.
• 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
.

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.
WARNING:
• Be sure to remove the service plug in order to disconnect the high voltage circuits before perform-
ing inspection or maintenance of high voltage system harnesses and parts.
• The removed service plug must always be carried in a pocket of the responsible worker or placed in
the tool box during the procedure to prevent the plug from being connected by mistake.
• Be sure to wear insulating protective equipment consisting of glove, shoes, face shield and glasses
before beginning work on the high voltage system.
• Never allow workers other than the responsible person to touch the vehicle containing high voltage
parts. To keep others from touching the high voltage parts, these parts must be covered with an insu-
lating sheet except when using them. Refer to
GI-34, "High Voltage Precautions"
CAUTION:
Never bring the vehicle into the READY status with the service plug removed unless otherwise
instructed in the Instruction. A malfunction may occur if this is not observed.
REMOVAL
WARNING:
Disconnect high voltage circuit. Refer to
GI-33, "How to Disconnect High Voltage"
.
1. Check voltage in high voltage circuit. (Check that condenser are discharged.)
a. Lift up the vehicle, and then remove Li-ion battery under covers. Refer to
b. Disconnect high voltage connector from front side of Li-ion battery. Refer to
.
c. Measure voltage between high voltage harness terminals.
