Replace Dometic Brisk II with Furrion Chill Cube in Forest River RV
Replace Dometic Brisk II with Furrion Chill Cube in Forest River RV
What is involved in replacing my Dometic Brisk II rooftop A/C in my 38’ Forest River Cherokee bunkhouse (30 amp, single A/C) with a Furrion Chill Cube, and do you recommend it considering startup current draw and generator use with a soft start?
A Chill Cube replacement needs the exact equipment and RV installation checked first. The description “38-foot Forest River Cherokee, 30-amp, single A/C” does not confirm whether the existing system is ducted or identify its thermostat, controller or wiring. Record the complete Brisk II rooftop, ceiling assembly and control labels, and have the installer verify the roof opening, thickness, support, clearances, duct layout and electrical circuit.
For the specific 18K ducted FACR18VSDA-PS-AM rooftop unit, Lippert 2024039645, the Chill Cube ducted manual, CCD-0009327 lists the FACT18VSDA-PS-AM ADB, 2024040312, as required and sold separately. The single-zone wall-thermostat and adapter kit, 2024047199, is optional. The system can use its documented ADB/panel and handheld-remote controls; a new wall thermostat is not mandatory for every installation. Reusing an existing Dometic control system is not verified here. Other Chill Cube capacities, heat-pump versions or non-ducted configurations need their own model-specific parts and instructions.
Do not carry over the earlier aftermarket soft-start recommendation. Lippert's 18K Chill Cube information says its variable-speed compressor ramps up and eliminates the need for an aftermarket soft-start device. We have not verified a SoftStartRV or Micro-Air device for this unit or a 70-percent surge reduction. Do not add one based on this answer.
A generator recommendation still requires its continuous output, inverter capability, operating conditions and simultaneous RV loads to be checked against the exact A/C requirements. Lower compressor startup demand does not guarantee that this coach can run the A/C plus other appliances on its generator or 30-amp service. The cited ducted manual specifies a dedicated 20-amp A/C circuit; the RV's overall service rating is a separate limit. Have a qualified installer confirm the complete electrical and control arrangement and cooling suitability. No wiring adaptation, generator size or drop-in conversion is approved by this page alone.
