Notes:
1. Compressors are Trane 3D™scroll.
2. EER and IEER are rated in accordance to the AHRI Standard 340/360-2010. Based on 80/67°F (26.7/19.4°C) to the evaporator coil, nominal airflow
and 85-95°F (29.4-35°C) condenser water or 95° F (35° C) ambient.
3. All units operate with R-410A. Water Cooled units ship with full operating charge. Air-cooled Units ship with dry nitrogen charge. Field refrigerant
system charge required. Refer to Table 3, p. 23 for amounts required.
4. Maximum cfm limits are set to prevent moisture carryover on the evaporator coil.
5. Minimum cfm limits are set to ensure stable thermal expansion valve operation at low load conditions.
6. Filter sizes are for units without hot water or steam heating coils
