Questions buyers ask
Questions buyers ask
Is this everything I need?
Yes, for a non-ducted RV: unit, ceiling assembly, gasket. Four bolts and about two hours. Add the soft start if you camp on a small generator, and the heat strip if you want shoulder-season heat.
Will it run on my Honda EU2200i?
With the 1497-3601 soft start, yes. Without it a 15,000 BTU unit needs about 3,500 W to start.
Do I need a wall thermostat?
No. The controls are on the ceiling assembly.
How do I know my RV is non-ducted?
Cold air comes out of the air conditioner itself, not from vents along the ceiling. If you have ceiling vents, you need the ducted kit.

About Coleman-Mach
About Coleman-Mach
Coleman-Mach rooftop air conditioners are built by Airxcel in Wichita, Kansas, and have been since 1967. They are the original equipment on more RVs than any other brand, which is why the ceiling assemblies, controls and repair parts are still available for units twenty years old. Every unit carries the Coleman-Mach 2-year limited warranty; Kate RV handles the claim with Airxcel for you.
