      • Semi-center location air conditioning unit

      • Laminate type evaporator

      • Sub-cool condenser assembly

  4. PRECAUTION

    1. Precaution for Refrigerant HFO-1234yf

      1. The parts used in the refrigerant cycle, the compressor oil, etc. of a HFO-1234yf system are not compatible with a conventional HFC-134a system.

      2. Always use HFO-1234yf as the refrigerant.

        Note:

        • Do not charge the system with refrigerant near open flames, as HFO-1234yf is combustible.

        • When charging the system with refrigerant, make sure the area is well ventilated (especially be careful in areas where the gas can easily accumulate such as under lifts and in garage pits, as the gas is heavier than air).

        • Follow any local regulations regarding combustible gases.

        • Be sure to use a refrigerant recovery unit that is compatible with HFO-1234yf systems.

        Tip:

        The shape of the service port for refrigerant charging has an exclusive design conforming to international standards for HFO-1234yf to prevent improper refrigerant charging.
