Notes:
1. Compressors are Trane 3-D™ scroll.
2. All units operate with R-410A. Units ship with a dry nitrogen holding charge. Field refrigerant system charge required. Refer to Table 4, p. 17 for
amounts required.
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.

Notes:
1. Refrigerant charges are listed as circuit 1 circuit 2 and provide only an estimate. Final charge requires sound field charging practice.
2. Operating charge is for entire system, which includes the air–cooled self–contained, remote air–cooled condenser, and 25 feet of interconnecting
refrigerant piping.
3. At conditions of 95° F (35° C), condenser storage capacity is 95% full.
4. To determine the correct amount of refrigerant needed for a particular application, reference the Trane Reciprocating Refrigeration Manual.
