The ADP 76793500 is a vertical evaporator coil drain pan designed for residential HVAC systems using slab-style A and B configuration evaporator coils. The pan measures 14 inches in width and fits the HE Series line of ADP coil assemblies sized 08 through 15. Its primary function is to collect and channel condensate that forms on the evaporator coil surface during normal cooling operation, preventing moisture from reaching the air handler cabinet or surrounding structure. HVAC technicians install this pan as a direct OEM-style replacement when the original drain pan cracks, warps, or develops leaks that compromise condensate management.
This drain pan is intended for vertical coil installations within split-system air conditioning and heat pump applications. It is specifically matched to ADP HE Series slab evaporator coils in the 08 through 15 capacity range. Typical installation occurs inside a residential air handler or furnace-mounted coil cabinet where a vertical coil orientation is used. The 14-inch width corresponds to the coil cabinet footprint for this size class, making it a targeted fit for that specific coil family rather than a universal pan.
Designed for use with ADP HE Series Slab A/B evaporator coils, models 08 through 15, in a vertical coil configuration with a 14-inch cabinet width.
Installation should be performed by a licensed HVAC technician. Shut off power to the air handler and turn off the system at the thermostat before removing the existing drain pan. Verify that the primary condensate drain line is clear and properly sloped before reinstalling the pan assembly. Inspect the secondary drain port and float switch wiring, if present, before returning the system to service.
