Will the Furrion Chill Cube Work w/ the Cummins Onan QG 4000i Onboard RV Generator?

Question

Question:

I have a 2015 forester 3011ds. I want to upgrade the ac with this but not sure if my Cummins Onan RV QG 400 generator is capable of handling the new unit. Will I be able to use this unit as a replacement?

Hey Joseph, it sure will. The Furrion Chill Cube RV Air Conditioner item # LC34DX is most likely going to be more efficient that what you're currently running. It only pulls 1,330 watts while drawing 11.6 amps.

The Furrion Chill Cube item # LC34DX has the new R32 refrigerant, which is far more efficient. Your Cummins Onan QG Generator item # CM42ZR is going to have no problems keeping up with this AC unit.

Please note that due to the new R32 refrigerant none of the Chill Cube components like item # LC34DX are backwards compatible with any existing systems. In order to use the Chill Cube you'll need to upgrade your entire AC system with one of the following options:

If you have a ducted system you will want the Furrion Chill Cube RV Air Conditioner w Air Distribution Box item # FR39TD.

If you have a ductless system you'll need the Furrion Chill Cube RV Air Conditioner w Air Distribution Box item # FR27TD.

If your RV has a furnace you'll have to install the Furrion Chill Cube RV AC w/ Air Distribution Box item # FR49TD, which includes the thermostat you'll need to control your furnace.

What AC system do you currently have in your Forest River?

It’s a dometic but not sure exact model. It is the original that came on the RV when I bought it new in 2015

@JosephK We don't have anything that works with Dometic anymore so replacing the entire system with Furrion would definitely give you a noticeable upgrade. Do you have a furnace, or plan on adding one?

@JerredH I have a furnace in the RV. The Dometic is supposed to have a heat pump as well but it quit working a couple years ago so just the furnace. Can you tell me all the parts I would need to get to install it? I currently have a wall mounted thermostat from Dometic and would like to at least use the wires there and replace the wall control and also be able to use it for the furnace

@JosephK I sure can. Since you have a furnace and your trailer is wired for a thermostat, you'll want the Furrion Chill Cube RV AC w/ Air Distribution Box item # FR49TD. You'll be able to install the Furrion thermostat using your existing wiring.

Answer 1

To install the Dometic water heater part #DMC74FR in place of your current Dometic setup what you need is the adapter part #DMC24FR and you'd be set.

Hey John, thanks for the picture that looks like it came from the instructions and your thermostat. You do need to move the first and last dipswitches up and that will allow both the furnace and the heat pump to function.
