Description
Dometic FJX5557MBKCS is the black 15,000 BTU FreshJet 5 low-profile rooftop air conditioner. It provides cooling only and uses R32 refrigerant. This mechanical rooftop variant has a built-in hard-start system but no preinstalled indoor controls, so the compatible air distribution box or return-air grille and control kit must be selected for the RV.
Manufacturer Model and Installation Notes
Dometic identifies this black FreshJet 5 model as a low-profile, cooling-only R32 rooftop unit. Its current installation manual lists 12.8 A rated compressor current for FJX5557MBKCS and 20 A circuit protection, although other Dometic manual revisions report different compressor amperage. Confirm the actual rooftop nameplate and applicable installation instructions before sizing the electrical supply.
Non-ducted installations require a compatible air distribution box. Ducted installations require a return-air grille and appropriate control kit. This rooftop unit does not itself include a wall thermostat or ceiling assembly; use the complete model number to match any existing Penguin II control arrangement.
