Description
While relatively new to the North American market, this third generation Dometic CoolAir been around for over ten years in Europe and are designed to provide the maximum amount of cooling while consuming less energy than their predecessor models. In fast, the new RTX 1000 rooftop units generate more than twice the cooling power at the same running time. All of this is possible thanks to the use of a variable speed inverter compressor, which makes for excellent cooling performance and amazingly efficient and quiet operation. In addition, the CoolAir is amazingly quiet with it’s two-cylinder compressor and features a large, high-contrast display that shows the individually adjustable air distribution, the four operating modes – and the adaptive automatic mode of the air conditioner.
Note: unlike most rooftop air conditioners and vent fans that use a square 14″ x 14″ hole/opening on the roof, this unit requires a slightly larger 14.5″ x 14″ opening. A larger, cardboard template that is roughly 19″ x 15″ is included in the box but you can actually use a smaller opening. This video details this opening size well. So does this video.

The image above shows the unit upside down and the various measurements on the unit. It’s sometimes helpful to know the space between the outside edge of the interior control panel/vents and the outside edge of the exterior unit.
