Installation [06/2020 - ]: Procedure

1. Sufficiently apply compressor oil to 2 new O-rings and the fitting surface of the HV supply battery assembly.

   Compressor Oil

   ND-OIL 11 or equivalent

   NOTE:

   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 leakage of electric power.

2. Install the 2 O-rings to the valve to connector tube.
   NOTE:

   Keep the O-ring and O-ring fitting surface free of foreign matter.

3. Install the valve to connector tube to the HV supply battery assembly with the bolt.

WARNING:

• Because the weight of the HV supply battery assembly is extremely heavy, make sure to follow the work procedures described in the appropriate service information.
• If work is not performed according to the procedures described in the appropriate service information, there is a danger that the components could fall down.
• Do not damage the HV supply battery assembly with the fork etc.
• Be sure to wear insulated gloves and protective goggles.

   NOTE:

   • Do not allow foreign matter, such as grease or oil, to adhere to the bolts of the HV supply battery assembly.
   • To prevent the wire harness from being caught, make sure to bundle the wire harness using insulating tape or equivalent.
   • Since the HV supply battery assembly is very heavy, 2 people are needed to remove it. When removing the HV supply battery assembly, be careful not to damage the parts around it.
   • When removing/installing/moving the HV supply battery assembly, make sure not to tilt it more than 80°.
   • If the HV supply battery assembly has been struck or dropped, replace it.
   • Do not apply any load outside of the area that can touch the ground.
2. Raise the HV supply battery assembly until there is no clearance between the HV supply battery assembly and vehicle.
   NOTE:

   Be careful not to drop the HV supply battery assembly.

3. Install the HV supply battery assembly to the vehicle body with the 8 bolts (A), bolt (B).
