[Specifications With Heat Pump Applied]

WARNING: This page is about a different car, the 2019 Kia Niro EV. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
  • Be sure to read and follow the "General Safety Information and Caution" before doing any work related with the high voltage system. Failure to follow the safety instructions may result in serious electrical injuries.
  • Be sure to shut off the high voltage before doing any work related with the high voltage system

    (Refer to "HIGH VOLTAGE SHUT-OFF PROCEDURES "). Failure to follow the safety instructions may result in serious electrical injuries.

  1. Recover the refrigerant with a recovery/recycling/charging station.
    CAUTION:
    • Do not use the same A/C recovery/charging station as conventional belt-driven compressors.
    • Since the electric compressor uses high-voltage, you should use POE oil which have high volumetric resistivity.
    • If PAG oil mixes into the POE oil of the system, dielectric breakdown may occur due to decreased volumetric resistivity and the A/C compressor may not work.
  2. Disconnect the negative (-) battery terminal.
  3. Shut off the high voltage circuit.

    (Refer to Battery Control System - "HIGH VOLTAGE SHUT-OFF PROCEDURES ")

  4. Remove the front bumper assembly.

    (Refer to Body - "FRONT BUMPER ASSEMBLY ")

  5. Remove the front bumper beam assembly.

    (Refer to Body - "FRONT BUMPER BEAM ASSEMBLY ")

  6. Remove the front active air flap assembly

    (Refer to Air Conditioning System - "CONDENSER ")

  7. Remove the receiver-drier (A) after loosening the mounting bolts.

  8. To install, reverse the removal procedure.
    NOTE:
    • Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing them. Be sure to use the right O-rings for R-1234yf to avoid leakage.
    • Charge the system, and test its performance.
