Air-Vantage Conversion Kit

Dometic to Coleman-Mach Ducted Rootop Conversion Kit for AC or Heat Pump Replacement

The AIR-VANTAGE KIT allows you to use the existing CT wall thermostat, control box, and ducted ceiling plenum to install Coleman-Mach air conditioners and heat pumps.  The kit components provide electrical and mounting changes required to install a new Coleman-Mach rooftop unit.  If the current system is not controlled by a CT wall thermostat, AIR-VANTAGE will not provide the necessary components for replacement.

This kit is intended to allow replacement installation of a Coleman-Mach rooftop air conditioner or heat pump while still utilizing the original Dometic ducted ceiling grille with single zone control box and “CT” wall thermostat (See Illustration Above). NOTE: Not to be used to replace a rooftop unit with a 3 speed blower – for use with 2 speed, single zone control boxes only.
