Technical Overview
Overview & Function
The Dometic FJX5557EHPWHCS FreshJet 5 white 15K heat pump delivers ducted or non-ducted heating and cooling through standard 14x14 vents on 115V supply. Fifteen thousand BTU with heat-pump shoulder-season heating covers big coaches on campground power. White finish suits bright roofs.
Fitment & Compatibility
This unit fits 14x14 vent openings with 115V 15.3A supply and ducted or non-ducted distribution per configuration. Verify the 40.39-inch roof footprint plus clearances. Gravity condensate drainage needs proper routing.
Technical Construction & Specifications
The 15K heat-pump circuit with 15.3A compressor draw on 115V follows the FJX5557 specification without condensate pump in this configuration. White low-profile housing suits tall-coach clearances. Controls pair with the matched thermostat.
Installation & Maintenance Guidelines
Two-person rooftop set with power off: fresh gasket, square placement, even torque, and heat-pump wiring per diagram. Route gravity drains with fall, then commission cooling, heating, and fan modes fully.
