1.Hot gas from compressor flows through the 4-way valve and is directed to the indoor coil. It is then condensed and subcooled through the coil circuits and then leaves the indoor coil by way of the ID Accurater in the bypass position to the liquid line.

2.The refrigerant then feeds the outdoor coil through the OD Accurater device in the metering position and distributes to each circuit.

3.Each circuit evaporates the refrigerant and the circuits are combined in the outdoor coil header.

4.The refrigerant then flows through the 4-way valve, accumulator, and back to the compressor.
