Installation

AIR CONDITIONING: ELECTRIC INVERTER COMPRESSOR: INSTALLATION

INSTALLATION

1. INSPECT COMPRESSOR OIL

(a) Gradually discharge inert gas (helium) from the service valve when replacing the electric inverter compressor with a new one. Drain the following amount of oil from the new electric inverter compressor before installation.
Standard amount:
(Oil capacity inside new electric inverter compressor 100 + 15 cc (3.52 + 0.53 fl.oz.)) - (Remaining oil amount in the removed compressor assembly with the motor (with motor compressor assembly)) = (Oil amount to be removed before installation)
NOTICE:
- Observe the precautions on the cooler removal/installation procedures when checking the amount of compressor oil.
- Because compressor oil remains in the pipes of the vehicle, if a new compressor is installed without removing the oil inside, the amount of oil becomes too great, preventing heat exchange in the refrigerant cycles and causing refrigerant failure and/or abnormal vibration.
- Check for oil leakage if the remaining oil amount in the removed compressor is too low.
- If any compressor oil other than ND-OIL 11 is used, compressor motor insulation performance may decrease, resulting in a leakage of electric power.

2. INSTALL ELECTRIC INVERTER COMPRESSOR ASSEMBLY

(a) Temporarily install the compressor with the 2 bolts.
NOTE: Install the bolts in the order indicated in the illustration.

(b) Fully install the compressor with the 2 bolts.
Torque: 25 Nm (255 kgf-cm, 18 ft-lbf)
NOTE: Tighten them in the order indicated in the illustration.

(d) Connect the wire harness.
NOTE: Wear insulated gloves when performing the procedures.
(1) Connect the 3 wire harness clamps.
(2) Connect the connector. (1)
(3) Lock the green-colored lock. (2)
3. INSTALL SUCTION HOSE SUB-ASSEMBLY

(a) Sufficiently apply compressor oil to a new O-ring and the fitting surface of the electric inverter compressor assembly.
Compressor oil:
ND-OIL 11 or equivalent
NOTICE:
- Do not use any compressor oil other than ND-OIL 11.
- If any compressor oil other than ND-OIL 11 is used, compressor motor insulation performance may decrease, resulting in a leakage of electric power.

(b) Install the O-ring to the suction hose.
(c) Install the suction hose with the bolt.
Torque: 9.8 Nm (100 kgf-cm, 87 in-lbf)
4. INSTALL DISCHARGE HOSE SUB-ASSEMBLY

(a) Sufficiently apply compressor oil to a new O-ring and the fitting surface of the electric inverter compressor.
Compressor oil:
ND-OIL 11 or equivalent
NOTICE:
- Do not use any compressor oil other than ND-OIL 11.
- If any compressor oil other than ND-OIL 11 is used, compressor motor insulation performance may decrease, resulting in a leakage of electric power.

(b) Install the O-ring to the discharge hose.
(c) Install the discharge hose with the bolt.
Torque: 9.8 Nm (100 kgf-cm, 87 in-lbf)
5. INSTALL SERVICE PLUG GRIP
6. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
7. PERFORM INITIALIZATION
(a) Perform initialization Repair Instruction - Initialization.
NOTE: Certain systems need to be initialized after disconnecting and reconnecting the cable from the negative (-) battery terminal.

8. INSTALL REAR NO. 3 FLOOR BOARD
9. INSTALL DECK FLOOR BOX REAR
10. INSTALL REAR NO.2 FLOOR BOARD
11. CHARGE REFRIGERANT Service and Repair
12. WARM UP COMPRESSOR Service and Repair
13. INSPECT FOR REFRIGERANT LEAK Service and Repair
