Carrier 343470-75102 Drain Pan

The Carrier 343470-75102 Drain Pan is a critical OEM replacement component engineered for condensate management in specific Carrier, Bryant, and Payne air handlers. This pan is the direct replacement for discontinued part 328140-752, as well as older part numbers 321379-752 and 314866-402, ensuring a precise fit without the need for field modifications. Designed for versatile horizontal or vertical installations, it features high-density, corrosion-resistant construction to withstand the constant thermal cycling and moisture exposure of high-efficiency cooling cycles. The condensate collection system is optimized for rapid drainage with a standard 3/4-inch NPT connection, preventing stagnant water that leads to biological growth and HVAC water damage. Measuring approximately 23" x 23" x 5", this pan integrates seamlessly with PF1MNA and FA4A series coils. Using a genuine Carrier 343470-75102 pan ensures the secondary drain port and overflow switch clearance meet factory airflow and drainage specifications, maintaining the structural integrity of the fan coil assembly during heavy dehumidification loads.

• Direct OEM Fit: Drop-in replacement for the Carrier 328140-752 with exact mounting hole alignment and sensor ports.
• Corrosion Resistance: Fabricated from durable, non-metal materials to eliminate rust issues common in legacy galvanized condensate drain pans.
• Multipoise Compatibility: Engineered for both upflow and horizontal orientations to accommodate various air handler drain pan configurations.
• Leak Prevention: Precision-molded edges and structural ribbing ensure efficient condensate drainage and prevent warping under pan weight.

Common Questions:

Is the 343470-75102 a universal HVAC pan?
No, this is a Carrier Factory Authorized Part. While it replaces several older Carrier models, it is designed for specific fan coil geometries. Always verify your model and serial number before installation.

Can I use this for both vertical and horizontal airflow?
Yes, this replacement condensate pan is designed for multipoise applications, making it suitable for vertical or horizontal HVAC pan swap-outs in compatible air handlers.

Does this pan include the secondary drain plug?
This kit typically includes the pan assembly and necessary porting. Technicians should verify if additional PVC fittings or overflow switches from the original HVAC drainage system require replacement during the overhaul.
