Documentation:
Note: When the TW began production sizes were offered in 2 through 6 ton sizes (and a 10 ton model). Sometime around 2017-ish, the 6 ton size was discontinued. All TW models were made for 410a refrigerant. They were made with 410a until the end of 2024. Beginning in 2025, the TW model is made with 454b refrigerant. The documentation below is separated by refrigerant type.
