Installation Advantages
Compact, multi-position cabinet simplifies retrofit layouts. Pre-charge and TXV shorten install time, and compatibility with No-Vac® Quick Connect® line sets helps avoid field charging. Horizontal installs benefit from dual drains and the integrated side drain pan.
Environmental & Efficiency Features
R-454B provides lower GWP compared to legacy refrigerants. CoolGuard® corrosion-resistant construction supports long-term reliability, while the built-in A2L leak-detection sensor adds safety during operation and service.
Notes: Airflow limits depend on matched 1.5T/2T outdoor units and proper duct design. For clearances, drain configuration, and safety/charging requirements, always follow the installation manual.
