Notes:
1. Compressors are Trane 3-D™ 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.
5. Optional low flow fan (unit model number digit 23 = 1) is available ONLY when High Capacity option is selected (unit model number digit 5 = V).
