Notes:
1. Compressors are Trane 3-D™ scroll.
2. EER and IEER are rated in accordance to ARI Standard 340/360-2007. Based on 80/67° F (26.7/19.4 °C) to evaporator coil, nominal airflow and 85-
95 °F (29.4/35 °C) condenser water.
3. All units operate with R-410A.
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. Units ship with Dry Nitrogen Charge. Field refrigerant system charge required. Refer to Table 5, p. 14 for amounts required.
