Compatible Air Handler Combinations (Max 33,000 BTU)
This condenser supports 6K, 9K, 12K, and 18K MRCOOL 5th Gen air handlers. A minimum of 2 air handlers must be connected, and total combined capacity should be between 70% and 122% of the rated output (18,900 – 33,000 BTU).
Examples of valid combinations include:
- 12K + 12K + 6K = 30K
- 9K + 9K + 9K = 27K
- 18K + 12K = 30K
- 6K + 6K + 12K = 24K
- 9K + 12K + 6K = 27K
Recommended Wire Size
- Recommended: 10 AWG copper wire – supports 24A MCA and 25A max fuse
- One Size Smaller (12 AWG): Not recommended – may overheat under load and violate NEC code
- One Size Larger (8 AWG): Ideal for long wire runs or added safety margin to reduce voltage drop
Note: Always verify total indoor air handler capacity before ordering. MRCOOL DIY condensers are pre-charged with R-454B and are not interchangeable with R-410A systems. Specifications may vary by production batch.
