The space-saving CDX-HW series fan coil is only 10" high (11" with enclosure), thus allowing it to recess in a ceiling. Recessed ceiling fan coils save valuable floor space and eliminate costly "equipment" closets.

First Co's customer is ultimately responsible for confirming which fan coil models are compatible with selected outdoor unit(s) and which expansion valves are required. To determine certified indoor/outdoor matches, go to or contact the factory.

All CDX-HW fan coils include a 120/24V transformer and are completely pre-wired. A sloped drain pan allows positive drainage of condensate.
(-C) model: for CDX-HW fan coils installed within an enclosure, add "-C" after CDX-HW. For instance, ordering model 19CDXHW-C will include a CDX-HW fan coil factory installed in a # 9ECDX01 enclosure and your choice of either a solid or louvered panel. These fan coils are compatible with any source of hot water that doesn't exceed 180°F.

  • Factory installed service switch
  • Freeze protector on HW coil
  • Two speed fan operation
  • Drain pan has 3/4" NPT primary and secondary (overflow) fittings
