The HX series is compatible with most split-system condensing units and heat pumps (heat pumps with electric heat require field added kit.
First Co's customer is ultimately responsible for confirming which fan coil models are compatible with selected outdoor unit(s) and which expansion valves (if any) are required. To determine certified indoor/outdoor matches, go to www.firstco.com or contact the factory.
All HX fan coils include a 240/24V transformer and are completely pre-wired with 0 to 10 kW of electric heat. A sloped drain pan allows positive drainage of condensate. For HX fan coils factory installed within an enclosure, add "-C" after the kW in the model number. For instance, ordering model 18HX5-C will include an 18HX5 factory installed in a # 9EHX01 enclosure and your choice of either a solid or louvered panel.
