Compatible Air Handler Combinations (Max 61,000 BTU)
This high-capacity 6-zone condenser supports 6K, 9K, 12K, 18K, 24K, and even 36K 5th Gen air handlers. A minimum of 2 zones must be connected. Total indoor capacity must not exceed 61,000 BTU.
Sample valid combinations:
- 36K + 18K + 6K = 60K
- 24K + 12K + 12K + 9K = 57K
- 18K + 12K + 9K + 9K + 6K + 6K = 60K
- 12K + 12K + 12K + 12K + 12K = 60K
Recommended Wire Size
- Recommended: 6 AWG copper wire – supports 34A MCA and 40A fuse
- One Size Smaller (8 AWG): May be acceptable for short runs but could overheat under load—check local codes
- One Size Larger (4 AWG): Ideal for long wire runs—ensures minimal voltage drop and extra safety margin
Note: Condenser is pre-charged with R-454B refrigerant and is not backward compatible with R-410A systems. Please ensure total indoor load is within allowable limits and follow all installation guidelines.
