Manufacturer specifications and installation fitment

Exact rooftop model: Dometic FreshJet 3 FJX3573MBKAS, black mechanical-control rooftop air conditioner with nominal cooling capacity of 15,000 BTU/h. Dometic's model table lists 115V AC, 60Hz single-phase power, 13.6A compressor rated-load current, 3.3A fan-motor rated-load current, R-410A refrigerant, and a 20A time-delay circuit-protection device for this model.

Before installation: The manufacturer's mechanical-ADB instructions specify a 14.3-inch square roof opening (±0.1 inch). This nominally 14-inch RV opening must be measured; fit also depends on roof framing, air-distribution box, mounting pattern and wiring. Confirm the original rooftop model and whether the RV uses a matching mechanical air-distribution box or a separate electronic-control arrangement. The rooftop unit, interior ADB and wall thermostat must not be assumed interchangeable solely because the roof opening is similar.
