Notes:
1. Compressors are Trane 3-Dâ„¢ scroll.
2. All units operate with R-410A. Units ships with full operating charge.
3. Maximum cfm limits are set to prevent moisture carryover on the evaporator coil.
4. Minimum cfm limits are set to ensure stable thermal expansion valve operation at low load conditions.
