Installation

AIR CONDITIONING: ELECTRIC INVERTER COMPRESSOR:

INSTALLATION

1. ADJUST COMPRESSOR OIL






(a) When replacing the electric inverter compressor with a new one, gradually discharge the refrigerant gas from the cap, and drain the following amount of oil from the new electric inverter compressor before installation.
Standard:
(Oil capacity inside the new electric inverter compressor: 120 to 135 cc (4.2 to 4.8 fl.oz.)) - (Remaining oil amount in the removed electric inverter compressor) = (Oil amount to be removed from the new compressor when replacing)
- When checking the compressor oil level, observe the precautions on the cooler removal/installation.
- If a new electric inverter compressor is installed without removing some oil remaining in the pipes of the vehicle, the oil amount will be too large. This prevents heat exchange in the refrigerant cycle and causes refrigerant failure.
- If the volume of oil remaining in the removed electric inverter compressor is too small, check for oil leakage.
- Be sure to use ND-OIL 11 or equivalent for compressor oil.
- If any compressor oil other than ND-OIL 11 or equivalent is used, electric inverter compressor insulation performance may decrease, resulting in leakage of electric power.

2. INSTALL SERVICE VALVE
(a) Apply sufficient compressor oil (ND-OIL 11) 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 or equivalent.
- If any compressor oil other than ND-OIL 11 or equivalent is used, electric inverter compressor insulation performance may decrease, resulting in leakage of electric power.

(b) Install the O-ring onto the service valve.






(c) Install the service valve No.1 with the bolt.
Torque: 9.8 Nm (100 kgf-cm, 87 in-lbf)
3. INSTALL ELECTRIC INVERTER COMPRESSOR






(a) Install the electric inverter compressor with the 3 bolts.
CAUTION: Tighten the bolts in the order indicated in the illustration.

Torque: 25 Nm (255 kgf-cm, 18 ft-lbf)






(b) Connect the connector (A).
(c) Lock the green-colored lock (B).
NOTE: Wear insulated gloves when performing the procedures.

(d) Connect the connector (C).
4. INSTALL COOLER REFRIGERANT SUCTION HOSE NO.1
(a) Remove the attached vinyl tape from the hose.
(b) Apply sufficient compressor oil (ND-OIL 11 or equivalent) 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 or equivalent.
- If any compressor oil other than ND-OIL 11 or equivalent is used, electric inverter compressor insulation performance may decrease, resulting in leakage of electric power.

(c) Install the O-ring onto the cooler refrigerant suction hose No.1.






(d) Install the cooler refrigerant suction hose No.1 onto the electric inverter compressor with the bolt.
Torque: 9.8 Nm (100 kgf-cm, 87 in-lbf)
5. INSTALL COOLER REFRIGERANT DISCHARGE HOSE NO.1
(a) Remove the attached vinyl tape from the hose.
(b) Apply sufficient compressor oil (ND-OIL 11 or equivalent) 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 or equivalent.
- If any compressor oil other than ND-OIL 11 or equivalent is used, electric inverter compressor insulation performance may decrease, resulting in leakage of electric power.

(c) Install the O-ring onto the cooler refrigerant discharge hose No.1.






(d) Install the cooler refrigerant discharge hose No.1 onto the electric inverter compressor with the bolt.
Torque: 9.8 Nm (100 kgf-cm, 87 in-lbf)
