The units also include front-seating service valves and support long-line applications up to 250 feet equivalent length, providing installation flexibility for a variety of residential system layouts.
Professional installation is essential to ensure optimal performance and system longevity. Proper installation includes accurate system sizing, compatible indoor coil matching, correct refrigerant charging, and compliance with electrical and HVAC installation standards.
