Generated explanation

The illustration depicts an older triple-split heat pump with an indoor air handler and coil, a separate indoor compressor, and an outdoor fan-and-coil section. The indoor coil sits in the supply plenum above the air handler, beside the return-air duct. Refrigerant suction and liquid lines connect the separated equipment, passing through the exterior wall to the outdoor section. A condensate line runs from the indoor coil enclosure to a floor drain. No defects or improper installation practices are identified.
