Installation & Compatibility Note
⚠️ Size & Match Warning:Physical Size: This is a 4-ton unit, typically featuring a wider 24.5-inch cabinet. Please measure your installation space and existing duct plenum before ordering.
System Match: Must be paired with a matching R-454B Outdoor Unit (e.g., MO1HE-H48B-2A). Not compatible with R-410A condensers.
⚠️ Important Match: This Air Handler is designed exclusively for R-454B systems. It must be paired with a matching EVOX G2 Outdoor Unit (e.g., 48K EVOX G2 AHU MAUHE-H48B-2A). Do not attempt to install this unit with older R-410A condensers, as the refrigerants and oil types are incompatible.
