Installation
HEATING / AIR CONDITIONING: COMPRESSOR: INSTALLATION
1. ADJUST COMPRESSOR OIL
(a) When replacing the electric inverter compressor with a new one, gradually discharge the refrigerant gas from the service valve, and drain the following amount of oil from the new electric inverter compressor before installation.
Standard:
(Oil capacity inside the new electric inverter compressor: 130 to 145 cc (4.4 to 4.9 fl. oz.)) - (Remaining oil amount in the removed electric inverter compressor) = (Oil amount to be removed from the new compressor when replacing)
NOTICE:
* When checking the compressor oil level, observe the precautions on the cooler removal/installation.
* If a new compressor and magnetic clutch are installed without removing some oil, there will be too much oil in the system due to the oil remaining in the pipes of the vehicle. Excessive oil in the system prevents heat exchange in the refrigeration cycle and causes refrigeration failure.
* If the amount of oil remaining in the old compressor and magnetic clutch is too small, check the A/C system for oil leaks.
* Be sure to use ND-OIL 11 or equivalent for compressor oil. 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
(a) Temporarily install the electric inverter compressor with the 3 bolts.
(b) Install the electric inverter compressor with the 3 bolts.
Torque : 25 Nm (250 kgf-cm, 18 ft-lbf)
NOTICE:
Tighten the bolts in the order shown in the illustration to install the electric inverter compressor.
(c) Connect the connector [A] and lock the green-colored lock as shown in the illustration.
CAUTION:
Wear insulated gloves when performing the procedures.
(d) Connect the connector [B].
3. CONNECT SUCTION HOSE SUB-ASSEMBLY
(a) Remove the attached vinyl tape from the hose.
(b) Sufficiently apply compressor oil to a new O-ring and the fitting surface of the compressor and magnetic clutch.
Compressor oil:
ND-OIL 11 or equivalent
(c) Install the O-ring onto the suction hose sub-assembly.
NOTICE:
* Keep the O-ring and O-ring fitting surfaces free from dirt or any foreign objects.
* Do not use any compressor oil other than ND-OIL 11 or equivalent. If any compressor oil other than ND-OIL 11 or equivalent is used, compressor motor insulation performance may decrease, resulting in a leakage of electric power.
(d) Install the suction hose sub-assembly onto the compressor and magnetic clutch with the bolt.
Torque : 9.8 Nm (100 kgf-cm, 87 in-lbf)
4. CONNECT DISCHARGE HOSE SUB-ASSEMBLY
(a) Remove the attached vinyl tape from the hose.
(b) Sufficiently apply compressor oil to a new O-ring and the fitting surface of the compressor and magnetic clutch.
Compressor oil:
ND-OIL 11 or equivalent
(c) Install the O-ring onto the discharge hose sub-assembly.
NOTICE:
* Keep the O-ring and O-ring fitting surfaces free from dirt or any foreign objects.
* Do not use any compressor oil other than ND-OIL 11 or equivalent. If any compressor oil other than ND-OIL 11 or equivalent is used, compressor motor insulation performance may decrease, resulting in a leakage of electric power.
(d) Install the discharge hose sub-assembly onto the compressor and magnetic clutch with the bolt.
Torque : 9.8 Nm (100 kgf-cm, 87 in-lbf)
5. CONNECT NO. 2 RADIATOR HOSE
(a) Using pliers, grip the claws of the clip and slide the clip to install the No. 2 radiator hose.
6. ADD COOLANT (for Engine) Service and Repair
7. INSPECT FOR COOLANT LEAK (for Engine) Cooling System
8. INSTALL SERVICE PLUG GRIP Installation
9. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL
NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Repair Instruction - Initialization.
10. INSTALL REAR NO. 3 FLOOR BOARD Installation
11. INSTALL REAR DECK FLOOR BOX Installation
12. INSTALL REAR NO. 2 FLOOR BOARD (for Separate Type) Installation
