Manufacturer model specifications and installation check

Exact model FJX3573MWHCS: Dometic's model table identifies FJX3573MWHCS as the Polar White mechanical FreshJet 3 rooftop air conditioner, rated at 15,000 BTU/h. Its rated compressor current is 13.6A with 2.6A rated fan current. These values are model-specific, rather than proof that any existing ceiling control system will connect directly.

Installation requirements: Dometic specifies a 115V AC, 60Hz single-phase supply and 20A time-delay circuit protection for this configuration. The nominal roof opening is 14.3 in. x 14.3 in. (plus or minus 0.1 in.); the documented maximum tilt for this model family is 15 degrees in any direction. Verify the actual roof framing, gasket, ceiling depth, mounting pattern, existing control board, thermostat and air-distribution or return-air assembly before ordering. The indoor assembly and controls are not part of this rooftop unit.
