Notes:
1. Compressors are Trane 3D
®
scroll.
2. EER and IPLV are rated in accordance to the ARI Standard 340/360-93. Based on 80/67 F (26.7/19.4 C) to the evaporator coil, nominal airflow and 95 F (35 C) ambient.
3. All units operate with R-22. Units ships with a dry nitrogen holding charge.
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
