Coleman-Mach Mach 3 A/C Installation on a 2022 Keystone Cougar 29RKS| iN•Command Compatible RV A/C Upgrade

In this guide, we install a Coleman-Mach Mach 3 rooftop air conditioner on a 2020 Keystone Cougar that was factory pre-wired for an additional A/C system.

Many RV manufacturers offer this pre-wire option, making the installation much easier when adding a second air conditioner. This video walks through the complete installation process, including the Coleman-Mach iN•Command compatible RVC control box, wiring connections, and ceiling plenum installation.

Components installed:

● Coleman-Mach Mach 3 RV air conditioner

● Coleman-Mach 9430A751 control box

● Coleman-Mach 8430-3062/ 8430-8430-5501 plenum/ceiling assembly

AC ONLY!

We cover the steps needed to integrate the new A/C into the existing RV control system and get it communicating properly with the iN•Command network.

If your RV is pre-wired for a second A/C, this guide will help you understand what is involved before starting your own installation. Coleman-Mach offers ducted and non-ducted rooftop A/C systems along with compatible ceiling assemblies and control packages for RV applications.
